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.
