The LifeLabs Genetics BRCA1/2 test balances thoroughness with cost-effectiveness, speed, and usefulness and includes pre and post test genetic counselling. Our test focuses on two well understood and documented genes – BRCA1 and BRCA2 – to provide scientifically sound results with useful recommendations. An experienced, in-house geneticist and our genetic counsellors reviews family history details, interprets the test results, and makes recommendations on whether further testing is required. Combining test data and expert, objective interpretation with your physician’s knowledge of your goals and health status provides high quality, actionable insights.
An alternative to BRCA1/2 is an expanded gene panel (example: > looking at 20 genes at once) to flag any predisposition to cancer. LifeLabs genetics does offer expanded gene panels for hereditary cancer testing; however we believe that these type of panels are best ordered by genetic specialists in cancer genetics clinics after careful clinical assessment particularly when there is a complex medical and/or family history. These genetic specialists take into account important consideration, for example whetherexamining additional genes could reveal other genetic variants that might obscure definitive conclusions, results could possibly yield false-positives for extremely rare diseases, and results could indicate clinically insignificant risks due to limited research and current follow-up options.

The CanadinaGovernment recently passed Bill S-201 (a Canndian equivalent to the U.S. Genetic Information Nondiscrimination Act (GINA)). The bill states that it is unlawful to engage in genetic discrimination and prohibits companies requiring the disclosure of genetic testing results before providing goods or services or entering into a contract. LifeLabs Genetics never releases results to anyone other than the ordering physician. However, insurance companies categorize people according to the amount of risk they pose and charge different premiums based on those levels of risk. Insurance policy application forms may still include questions about your health, family history, age, occupation, etc. When those details are entered into an actuarial table, it may become evident that you are in a higher risk category based on your family historyPrint this Answer

A competitor to our BRCA 1/2 test examines 27 genes to flag any predisposition to cancer; however, examining additional genes usually reveals numerous genetic variants that can obscure definitive conclusions, yield false-positives for extremely rare diseases, and indicate clinically insignificant risks. Based on our current understanding of genetics today, having more data to work with is not necessarily better — in some cases, additional data makes moving forward more confusing. The LifeLabs Genetics BRCA 1/2, as a screen, provides all the information that you need to know to move forward.
The LifeLabs Genetics BRCA 1/2 test package includes genetic counselling. Please contact us with any questions you may have.Print this Answer
LifeLabs Genetics performs BRCA 1/2 testing basically in the same way as other types of hereditary conditions testing. We offer the following for BRCA1/2 analysis:
- Next generation sequencing (NGS): sensitivity >98.5%, specificity >98.2%, 100% coverage >20x
- Deletion/duplication via MLPA: sensitivity 99.9% and specificity 99.8%
- Sanger sequencing and familial mutation testing also available
Genetic testing is often compared to visiting a bookstore or a library. Perhaps that comparison may shed light on which type of BRCA 1/2 test to order:
- Sequencing looks at the entire gene, from beginning to end, to identify obvious and more subtle genetic mutations or variations. If a gene were a chapter in a book, sequencing could reveal a previously undetected, single-letter spelling mistake.
- Deletion/duplication, or multiplex ligation-dependent probe amplification (MLPA), looks for “larger pieces” of missing genetic information or extra, duplicated portions of the gene. If a gene were a book chapter, deletion/duplication testing could find the missing paragraph or pages. Deletion/duplication testing could also flag where a paragraph has been erroneously added multiple times to a book.
- Family mutation testing uses previously identified genetic mutations and familial hereditary patterns to pinpoint and examine a precise spot on a person’s genome. Family mutation testing confirms or rules out whether you have the same variation on the same gene as a family member. So, when comparing a gene to a book chapter, family mutation testing could find a specific quotation within the book. This type of testing is quite quick because you know exactly where in the book to look and do not have to read the whole chapter.
Genetic sequencing and deletion/duplication testing are normally ordered together for the most complete results.

Studies* indicate that Panorama™ identifies Trisomy 21 (Down syndrome) and Trisomy 13 (Patau syndrome) with >99% sensitivity and false-positive rates of 0%, while another popular test reports sensitivities of, respectively, 79% and 50% with 5% and 0.3% false-positive rates.
Panorama™ has a >96% detection rate for Trisomy 18, with a false positive rate of <0.1%, while that same competing test has 80% sensitivity and a 0.3% false positive rate.
Panorama™ screens for Monosomy X (Turner syndrome), triploidy, fetal sex, and optional microdeletion syndromes while the other popular test does not screen for these conditions at all.
Panorama™ is the superior option.

Panorama™ is able to detect the following conditions caused by chromosomal anomalies:
- Down syndrome: This is caused by an extra copy of chromosome 21 and is also known as trisomy 21. This is the most common genetic cause of intellectual disability and individuals with Down syndrome have some degree of intellectual disability and/or defects of the heart or other organs. Some have other medical conditions, including hearing or vision loss. Approximately 1 in 750 babies is born with this condition; many live into their 60s or longer.
- Edwards syndrome: This is caused by an extra copy of chromosome 18 and is also known as trisomy 18. Most babies with trisomy 18 have severe intellectual disability and multiple severe birth defects. Poor growth during pregnancy is common and many babies are miscarried or stillborn. Of those babies born alive, most die before one year of age. Approximately 1 in 3,000 babies is born with trisomy 18.
- Patau syndrome: This is caused by an extra copy of the chromosome 13 and is also known as trisomy 13. Babies with this condition require significant medical care because they have severe intellectual disability and birth defects. Pregnancies diagnosed with trisomy 13 are at high risk for miscarriage or stillbirth. Similar to trisomy 18, of those babies born alive, most die before one year of age. Approximately 1 in 5,000 babies is born with trisomy 13.
- Turner syndrome: This is caused by a missing copy of the X chromosome and is also called Monosomy X. The condition only affects girls. Individuals with Monosomy X are shorter than average and often have infertility as adults. Some girls have heart or kidney defects, hearing problems, and some have minor learning disabilities. Girls with Monosomy X may need growth hormone treatments in early childhood and usually need sex hormone treatments at the time of puberty. Approximately 1 in 5,000 girls are born with Monosomy X.
- Triploidy: In triploidy, the fetus has 3 copies of each chromosome instead of two (a total of 69 chromosomes rather than 46). Approximately 1 in 100 conceptions are affected with triploidy. Most pregnancies with triploidy will miscarry in the early part of the first trimester, although later miscarriage or stillbirth can occur. The majority that survive die shortly after birth. Triploidy places the mother’s health at risk from pregnancy complications like pre-eclampsia, postpartum hemorrhage, and molar pregnancy with malignancy potential.
Microdeletions: When small pieces of genetic information are missing within a chromosome, they are called microdeletions. Microdeletions can affect health and development and occur in collectively 1 in 1000 pregnancies. The severity of the health impact is based on which chromosome information is missing.
- 2 Deletion syndrome: The 22q11.2 deletion syndrome, also called DiGeorge syndrome or Velo-Cardio-Facial syndrome (VCFS), is caused by a missing piece of chromosome number 22. About one in every 2,000 babies is born with the 22q11.2 deletion syndrome. The majority of children with this disorder have heart defects, immune system problems, and specific facial features. Most children with 22q.11.2 deletion syndrome have mild-to-moderate intellectual disability and speech delays; some will also have low calcium levels, kidney problems, feeding problems, and/or seizures. About 1 in 5 children with the 22q11.2 deletion syndrome have autism spectrum disorder; 1 in 4 adults with 22q11.2 deletion syndrome have a psychiatric illness, like schizophrenia.
- Prader-Willi syndrome: Prader-Willi syndrome occurs when either a small piece of chromosome 15 is missing or when both copies of chromosome 15 come from the same parent (called uniparental disomy, or UPD). Babies with Prader-Willi syndrome have low muscle tone and problems with growth and feeding. Children with Prader-Willi syndrome have delayed milestones, short stature, rapid weight gain leading to obesity, and intellectual disability. About 1 in 10,000 babies are born with Prader-Willi syndrome.
- Angelman syndrome: Angelman syndrome happens when either a small piece of chromosome 15 is missing, or when both copies of chromosome 15 come from the same parent (called uniparental disomy, or UPD). About 1 in 12,000 babies is born with Angelman syndrome. Babies and children with Angelman syndrome have severe intellectual disability, delayed milestones, seizures, and problems with balance and walking.
- 1p36 Deletion syndrome: 1p36 deletion syndrome, also referred to as Monosomy 1p36 syndrome, is caused by a missing piece of chromosome 1. Children with 1p36 deletion syndrome have intellectual disabilities. Most have heart defects and weak muscle tone. About half of affected individuals have seizures (epilepsy), behavioral problems, and hearing loss. Some children with 1p36 deletion syndrome also have vision problems or additional birth defects of other organs. About 1 in 5,000 newborn babies has 1p36 deletion syndrome.
- Cri-du-chat syndrome: A missing piece of chromosome 5 causes Cri-du-chat syndrome, also called 5p- (5p minus) syndrome. The name “Cri-du-chat” was given to this syndrome due to the high-pitched, cat-like cry that babies with this syndrome often make. Babies with Cri-du-chat syndrome typically have low birth weight, a small head size, and weak muscle tone. Feeding and breathing problems are common. Children with this disorder have moderate-to-severe intellectual disability, including speech and language delays. They may also have growth delays, behavior problems, and some have curvature of the spine (scoliosis). About 1 in every 20,000 babies is born with Cri-du-chat syndrome.
The post-test risk or risk after test is either resulted as a “high risk” or “low risk” and is an absolute risk value that is calculated based on the Panorama algorithm as well as the positive predictive value of the test based on the clinical experience data and validation studies.
A post-test “high risk” result is thus an indication of how likely the fetus is going to be affected for that particular condition.
A post-test “low risk” result is thus an indication of how likely the fetus is NOT affected with the condition.Print this Answer
A high risk “twin/vanishing twin/triploidy” result means that the Panorama algorithm detected an extra DNA pattern in the sample. This could mean a few different things: the pregnancy may be a twin pregnancy that you didn't know about yet, the pregnancy may have started as a twin pregnancy but one of the twins didn’t survive (also called vanishing twin) and rarely, the pregnancy could be affected with a condition called triploidy where there is a whole extra set of chromosomes present.
It is highly recommended to have a dating ultrasound prior to having the Panorama, not only for dating the pregnancy, but also to determine if there may be ongoing twins or possibility of a vanishing twin. In vanishing twin pregnancies, NIPT is not recommended. Alternate screening such as maternal serum testing or nuchal translucency ultrasound would be more appropriate. If there is a vanishing twin pregnancy, Panorama will not be able to provide a result and there will not be a refund option as this result could have clinical implications.Print this Answer
A high risk result does not mean the baby definitely has a chromosomal anomaly; rather, it indicates a very high probability that your baby has that condition. No irreversible decisions should be made without follow-up diagnostic testing (CVS/amniocentesis). Please follow up with your healthcare providers about next steps. Again, LifeLabs Genetics is here to assist you and your healthcare provider along the way. For more resources regarding specific syndromes, please visit the following links:

- 1p36 Deletion syndrome (https://rarediseases.info.nih.gov/diseases/6082/chromosome-1p36-deletion-syndrome)
A low risk results indicates that it is very unlikely that your baby is affected by one of the conditions on the Panorama Panel selected. Although Panorama results are very accurate, routine monitoring of a pregnancy is still recommended, and your healthcare provider may recommend further testing depending on results of other prenatal tests and/or family history. Panorama is only a screening test, and although very infrequent, false negatives can occur.Print this Answer
If Panorama is not able to get a result for the full panel of testing even after a redraw, you will be refunded-if you paid for the test.
If Panorama provides partial results, you will not be refunded.Print this Answer
A partial result is when the Panorama provides a result for most of the conditions tested but is not able to provide a result for one (or more rarely, two conditions). There are various reasons for this to happen, but is not common. In these situations, your healthcare provider will be contacted by one of our board certified Genetic Counsellors to discuss the possible reasons why there was a partial result. Partial results are not eligible for refund.Print this Answer
If Panorama provides a “no result” it still means that the full test was performed and unfortunately the Panorama algorithm was not able to yield a result (could be for various reasons, like low fetal fraction or the DNA pattern was not able to be interpreted) therefore it does take the same amount of time to come to this conclusion.Print this Answer
There are many reasons why a “No Result” may occur on Panorama. Overall, 4-5% of cases may require a redraw and 65% of those cases will obtain a result on second attempt. No results may be due to an amount of fetal DNA in the sample that is below our testing cut off of 2.8% or there may have been some difficulties obtaining sufficient DNA or sequencing the DNA while it is processed in the laboratory. In many cases, the issue is sample specific and resolves with redraw. If you do not obtain a result after two attempts, the test cost will be refunded and one of our genetic counsellors will discuss recommendations for alternative screening with your care provider.Print this Answer
In a small percentage of cases (4-5%), Panorama may not be able to obtain sufficient information from your blood sample to determine an accurate result. In some cases, another sample may help provide additional information, if this is the case, you will be contacted for another sample. In the majority of cases (> 65%) we will get a result with the redraw. In rare cases, if we are unable to provide any results from the Panorama screen upon a second attempt, one of our board certified genetic counsellors will contact your physician to further discuss. Please follow up with your healthcare provider prior to visiting one of our Patient Service Centres (PSCs) for a redraw.Print this Answer
Panorama gives you a personalized probability score and tells you if there is a high or low probability that your pregnancy may be affected by screened conditions such as Down syndrome. Like other screening tests, Panorama does not provide a definitive diagnosis of the condition. As such, high risk results should be followed by diagnostic testing such as amniocentesis.Print this Answer
Your healthcare provider will get your results back in 7-10 calendar days from receipt of your sample at our testing laboratory. As results will be sent directly to your healthcare provider for their review, we recommend that you schedule an appointment with your healthcare provider two weeks after your blood sample is collected to review the results.

No. NIPT cannot be done for individuals with pregnancy involving vanishing twins, those who are bone marrow or organ transplant recipients, are carrying triplets or higher order multiples or individuals with twin pregnancies who conceived using an egg donor or surrogate. Other screening tools may be appropriate in these circumstances.Print this Answer
The Society of Obstetricians and Gynaecologists of Canada (SOGC) and the Canadian College of Medical Geneticists (CCMG) published a joint statement recommending NIPT as a highly effective screening test for trisomies 21, 18, and 13; that should be offered as an option when discussing prenatal screening. Additionally, in a large study published by Panorama’s company of origin, Natera, Panorama was shown to be a highly effective screen in both high and low risk populations.

Panorama is for all pregnant women interested in knowing more about the health of their baby.
Provincial healthcare coverage may be available in certain provinces for the following indications:
- 40 years of age or older at the time of delivery
- Positive serum screen result
- Nuchal translucency (NT) ≥ 3.5mm
- Previous pregnancy with a chromosome abnormality
Panorama™ is also appropriate for women carrying twins, and women who have used a donor egg or a surrogate.

Panorama NIPT is a blood test that can be done as early as 9 weeks which measures cell free DNA (cfDNA) from the mom and the placenta. It is Ministry of Health funded for some women (depending on provincial guidelines), but is also available as a private pay test. The basic Panorama option screens for trisomy 21, 13, 18, monosomy X, triploidy and the sex chromosome trisomies. Other conditions such as microdeletions and fetal sex are also available with NIPT. Some patients feel more comfortable with the better accuracy of the NIPT test compared to serum screens. An NIPT test provides fewer false positive and false negative rates which is why some women choose to pay for this test. See also Q15.Print this Answer
Maternal serum screening is a Ministry of Health funded screen for trisomy 21 and trisomy 18 (+/- neural tube defect). It involves a blood test(s) (with nuchal translucency ultrasound where available) and measures blood markers that are produced by the placenta and fetus.

The basic Panorama option screens for trisomy 21, 13, 18, monosomy X, triploidy and the sex chromosome trisomies. Fetal sex, as well as other conditions known as microdeletions, are also available. In addition, Panorama can typically provide results earlier in the pregnancy and provide information on more conditions than maternal serum screens.Print this Answer
No, not all NIPTs are the same. Here are the reasons Panorama is different:
- Panorama is the only NIPT to differentiate between mom and baby. Since Panorama uses single nucleotide polymorphism (SNP) technology, the test is able to identify DNA from mom separately from the baby's DNA.
- SNP-based NIPT has the least amount of false positives/false negatives because the test can detect confounding conditions such as:
- Vanishing Twins
whereas other NIPT tests cannot detect these conditions.
- Panorama is the only NIPT on the market with no incorrect sex calls in low risk pregnancies
And if you're having twins, Panorama can uniquely provide:
- Zygosity information
- Individual fetal fractions for dizygotic twins
- Determine fetal sex of each twin
“Negative predictive value” (NPV) is the chance that a low risk result is correct and that the pregnancy is NOT affected with the conditions screened. With Panorama NIPT the NPVs for all the conditions are greater than 99.9%.Print this Answer
"Positive predictive value” (PPV) is the chance that a high risk result is correct and that your pregnancy does in fact have the condition noted. With Panorama NIPT the PPVs are as follows:
- Trisomy 21: 91%
- Trisomy 18: 93%
- Trisomy 13: 38%
- Monosomy X: 50%
- Triploidy: 5.3%
- Sex chromosome trisomies: 89%
- 2 microdeletion syndrome (DiGeorge syndrome): 20%
- 1p36 microdeletion syndrome: 7-17%
- Angelman syndrome: 10%
- Cri-du-chat syndrome: 2-5%
- Prader-Willi syndrome: 5%"
Certain types of microdeletions can cause health problems for the baby that may need immediate care. Currently, microdeletions and associated syndromes are not screened on routine pregnancy screening, and may not have ultrasound findings. Early screening through Panorama can guide the management of pregnancy or allow decisions for the delivery and special needs of your child.
Babies with 22q11.2 deletion syndrome (also known as DiGeorge syndrome), for example, may have a lower level of calcium in their blood. Prenatal screening can help ensure doctors know they need to monitor your child’s levels from birth and supplement as necessary to prevent complications.
Note: Microdeletions, like the other chromosome anomalies screened on this test, are present from conception and are not normally inherited by a parent or related to something you or your partner did or didn’t do.Print this Answer
Detection: These conditions may often go undetected by traditional serum screening and ultrasounds.
Early intervention: Early screening can guide the management of the pregnancy or allow decisions such as delivery in a tertiary centre. For some of the conditions on the screen, early interventions can help reduce the risk of serious complications, as well as improve the health outcomes as the child continues to grow. Being prepared can provide the opportunity to plan for future medical needs such as surgery, medication, occupational therapy, physical therapy and special education.
Frequency of occurrence
Unlike Down syndrome, which occurs more frequently in mothers who are 35 and older, microdeletions occur in pregnancies at the same rate for mothers of any age. A 20-year-old has the same risk as a 45-year-old. Additionally, in most microdeletion cases, there is no previous family history as these chromosomal deletions typically occur by chance in the sperm or egg, leading to conception.Print this Answer
Due to the unique test methodology, Panorama screens for the five microdeletion syndromes associated with serious health issues:
- 2 deletion - DiGeorge syndrome
- Prader-Willi syndrome
- Angelman syndrome
- Cri-du-chat syndrome
- 1p36 deletion syndrome
You can choose to screen for the most common microdeletion, which is the 22q11.2 microdeletion, also known as DiGeorge syndrome. Alternatively, you can choose the full panel and screen for all five microdeletions.Print this Answer
A microdeletion is a small, missing piece of a chromosome. Some microdeletions are known to cause specific genetic syndromes with major health impacts to the baby—including intellectual disabilities and other health implications which can include heart and breathing issues, immune system problems, trouble feeding, or other problems that may need immediate care upon birth.
Unlike Down syndrome, which occurs more frequently in mothers who are 35 and older, microdeletions occur in pregnancies at the same rate for mothers of any age. When considering age and pregnancy together, the likelihood of a woman under the age of 28 having a child with a microdeletion syndrome is higher than Down syndrome (trisomy 21).Print this Answer
Yes, Panorama can be ordered for the following conditions in donor/surrogate singleton pregnancies:
- Genetic anomalies such as Trisomy 21 (Down syndrome), Trisomy 18 (Edwards syndrome), Trisomy 13 (Patau syndrome)
- Sex (optional)*
Yes, Panorama will be able to inform you if the twin pregnancy is dizygotic (fraternal twins) or monozygotic (identical twins). Panorama can also tell you the sex of each twin. The fetal fraction (amount of DNA in the sample that is from the pregnancy vs maternal DNA) needs to be at least 2.8% in one of the twins to determine this.Print this Answer
Non-invasive prenatal testing (NIPT) is a screening test done in pregnancy. It uses a blood sample from the mother to analyze DNA from the placenta which allows us to screen for conditions that could affect a baby’s health.Print this Answer
There is always genetic material (cell-free DNA) floating in our bloodstreams. When an individual is pregnant, pieces of genetic information from the placenta (cell-free fetal DNA) are released into their bloodstream and mix with their own genetic information. NIPT tests the mixture of DNA to determine if there is a high or low risk that the baby has certain chromosome anomalies. Fetal fraction, or the proportion of DNA in the blood sample that comes from the placenta, can affect the accuracy of an NIPT test.Print this Answer
Panorama can be done as early as 9 weeks of pregnancy.Print this Answer
NIPT screens for:
- Genetic abnormalities such as:
- Trisomy 21 (Down syndrome)
- Trisomy 18 (Edward syndrome)
- Trisomy 13 (Patau syndrome)
- Monosomy X (Turner syndrome)
- Trisomy X
- XXY (Kleinfelter syndrome)
- XYY (Jacob syndrome)
- Can identify your baby’s sex (optional)*
- Optional Microdeletions:
- 2 deletion - DiGeorge syndrome
- Prader-Willi syndrome
- Angelman syndrome
- Cri-du-chat syndrome
- 1p36 deletion syndrome
- Identical or Fraternal twins
- Genetic abnormalities such as:
- Trisomy 21 (Down syndrome)
- Trisomy 18 (Edward syndrome)
- Trisomy 13 (Patau syndrome)
- Can identify each baby’s sex (optional)*
If screen determines twins to be identical, Panorama can additionally screen for:
- Monosomy X (Turner syndrome)
- Trisomy X (Triple X syndrome)
- XXY (Kleinfelter syndrome)
- XYY (Jacob syndrome)
- 2 (DiGeorge syndrome) optional*
Detection rates are listed below:
Sensitivity (detection rate)
Trisomy 21 (Down syndrome)
Trisomy 18 (Edwards syndrome)
Trisomy 13 (Patau syndrome)
Monosomy X (Turner syndrome)
Triploidy/vanishing twin detection
Male or Female
Microdeletion syndromes (e.g., Angelman, Cri-du-chat, DiGeorge, Prader-Willi)
While it is not the intent of the test, the baby’s sex information can also be identified using Panorama™.Print this Answer
The Basic Panorama Panel screens for trisomy 21, 13, 18, monosomy X, triploidy and sex chromosome trisomies. Patients also have the option of finding out fetal sex as well.Print this Answer
An extra copy of any one chromosome - 3 copes instead of 2 - is called a trisomy (tri-meaning “three”). A missing copy of any chromosome - 1 copy instead of 2 - is called a monosomy (mono-meaning “one”).Print this Answer
Yes, Panorama can be done in twin pregnancies, as well as pregnancies conceived with an egg donor or surrogate pregnancies. Panorama can NOT be done in higher order multiple pregnancies (e.g. triplets, quadruplets, etc.) and can NOT be done in twin pregnancies conceived by an egg donor or surrogate. Some conditions may not be able to be screened for in twin pregnancies (e.g. triploidy, monosomy X, some microdeletion syndromes).Print this Answer
With this expanded carrier screen, you and your partner have the option to take the test independently (i.e., at different times) or at the same time. If you are already pregnant,taking the test together may allow more time for planning, decision making, additional testing, and early intervention, if necessary.Print this Answer
The test occasionally adds new, detectable conditions to the test protocol and additional details to its reports. If the test makes enhancements to the test during the gap(s) between pregnancies and you want to take advantage of those enhancements, you will have to pay for and take the test again. LifeLabs Genetics does not keep your sample on file for future test reruns.Print this Answer
No genetic test can provide a 100% guarantee that you will have a healthy pregnancy and a healthy baby. Expanded Carrier Screening looks at up to 288 different genetic conditions. The screen can identify over 99% of possible mutations in most of the genes screened, but it does not rule out all possible conditions.Print this Answer
All disease-causing variants relating to the phenotype reported in HGMD®, ClinVar and CentoMD® (classes 1 and 2), as well as all variants with minor allele frequency of less than 1% in the ExAC database are considered in the medical interpretation. Class 1, 2, and 3 variants are evaluated. Variants that possibly impair the protein sequence are prioritized. All relevant inheritance patterns are considered based on the family history and clinical information submitted with the sample(s). CENTOGENE continuously assesses variants as new information becomes available internally and in the medical literature. When familial studies are recommended, familial variant testing is available for a small fee.
LifeLabs Genetics and CENTOGENE adhere to the “ACMG Recommendations for Reporting of Incidental Findings” and will not report on incidental findings that are not listed in these guidelines. However, it does mean that we will report variants detected in certain genes or classes of genes that are outlined in these recommendations as being medically actionable. Patients who prefer not to receive this information in their report, can opt out of this service. In case of Trio analyses, incidental findings are only analysed for the index patient. Carrier information of the parents for identified incidental findings of the index can be requested with new consent from the parents. Findings will be issued on individual reports. Incidental findings are not reported for fetal samples or samples from deceased persons.Print this Answer
When you purchase a WES package from LifeLabs Genetics, you get sequencing of all exons, end-to-end bioinformatics analysis of raw data, validation or sequencing results, extensive and detailed reports, and access to the raw data. Each WES diagnostic report is validated by CENTOGENE’s team of renowned and experienced clinical specialists and cross-referenced against any family information provided as well as the CentoMD® mutation database. LifeLabs Genetics’ counsellors will also review, interpret, and speak with your physician when unexpected results are found.Print this Answer
Depending on your province of residence, ministry of health coverage could be available. It is always best to first discuss this type of funding with your physician—a referral to a genetics (or other) specialist may be required.
In some provinces, WES test costs are reimbursed only when ordered by a qualified geneticist. This is usually the case in Ontario, for example. Once the geneticist gains approval via a Ministry of Health and Long-Term Care letter, he/she can attach the Ministry’s approval letter to the requisition.Print this Answer
With different coverage depth, analysis types, turnaround time, and sampling (trio vs. single) options, it can be challenging to pick the right version of the WES test for you. Yes, please speak with your physician and/or contact us for ordering assistance to increase your chances of obtaining the specific information that you are looking for.Print this Answer
Genetic testing identifies whether you have a specific genetic mutation. It can also predict the likelihood of you passing on a disease-causing mutation to your children.
A positive result does not a guarantee that you, or your children, will develop a genetic disease. Other health, lifestyle, environmental, and genetic factors may play a role in influencing whether, or how, the disease develops.
We do know that, at this point, the vast majority of genetic diseases cannot be cured. However, depending on what the disease is, interesting and helpful options to prevent and manage genetic disease are emerging daily.Print this Answer
The WGS test is intended for individuals with serious, legitimate medical concerns, especially those who need a speedy diagnosis for a rare disease.
The WGS test can provide so much information that it can be overwhelming – sometimes the information can even be contradictory given our current understanding of the human genome. It is a medical-grade test that is really most valuable when a physician or genetic specialist is looking to understand more about a specific, unusual disease or condition. Please contact us to determine whether LifeLabs Genetics offers a genetic test that fulfils your needs.Print this Answer
No. You can go to any LifeLabs Patient Service Centre and have the sample drawn with or without an appointment. Self-collection is available for some tests (e.g., Counsyl).Print this Answer

There are no age limits on genetic testing. However, we do not recommend predictive genetic testing (e.g., BRCA 1/2) for children unless advised by your physician. Children should be given the right to make a decision about whether they want to find out their risks and illness susceptibility when they come of age. Many genetic illnesses have no known cure, and knowing too much may have impacts on their life choices. If possible, delay discussions about genetic testing until the child comes of age.Print this Answer

LifeLabs has a computer system that creates a unique patient identifier, usually based on your health card number. Once your sample is received at our lab or Patient Service Centre, we attach barcode stickers with this unique identifier to all paperwork and tubes/vials. This unique identifier can also be used to cross-reference test samples from your family members, if you have ordered a test that analyzes their samples as well. Barcode scanning ensures your name, specimen, and results are accurately matched through the entire testing process.Print this Answer

You or your healthcare provider can order a kit for sample collection. Some kits enable self-collection, but most require professional assistance. With a kit, your healthcare provider can draw/take the sample for you or perhaps make arrangements at a nearby lab. For certain tests (e.g., Counsyl and Panorama™), LifeLabs Genetics has made arrangements with third-party labs in other provinces, such as:
- Quebec – Biron Laboratoire Médical
- Manitoba – Diagnostic Services Manitoba (DSM)
- Alberta – DynaLIFE and Calgary Lab Services
Contact us for a full list of alternative labs/collection centres.
All kits submitted to LifeLabs Genetics must include a requisition form signed by your healthcare provider.
No, not without permission from the patient. LifeLabs Genetics shares test results only with the physician who ordered the test (i.e., signed the requisition). Generally speaking, it is up to the patient, or his/her legal caregiver or guardian, to decide who has access to the results after the physician provides them.Print this Answer

When your results are ready, a LifeLabs team member will fax them to your physician. Alternatively, if there’s an online portal for the test you’ve taken, your physician will receive an email indicating that results are ready for viewing on the password-protected, secure online portal. Results are shared only with the ordering physician. We do not release results to patients or their family members.Print this Answer
Signed requisition forms should be used within six months. After six months, you may be asked to obtain another signed form. Genetic test kits, which includes paperwork and tubes/vials, have best before dates. For more accurate results, obtain a signed requisition, provide a sample in a fresh kit according to the instructions, and ensure the sample is shipped to the lab (with the signed paperwork) on the same day it is collected.Print this Answer
To ensure samples are handled with care, LifeLabs uses its proprietary, internal courier service to transport samples between Patient Service Centres and the lab. If you do not plan to visit a Patient Service Centre, we recommend FedEx, which is included in the cost of the test, if you use the LifeLabs FedEx account number.
