LifeLabs launches Signatera, offering Canadians an innovative and personalized approach to managing cancer

February 1, 2023. – Toronto, ON: LifeLabs is pleased to share the launch of SignateraTM, a highly sensitive, personalized molecular residual disease assay (MRD) test developed by Natera for treatment monitoring and molecular residual disease (MRD) assessment in patients previously diagnosed with cancer.

The first of its kind, this innovative test uses circulating tumor DNA (ctDNA) and is personalized for each patient to help assess recurrence risk and identify relapse up to two years earlier than the current standard of care tools. The clinical utility of SignateraTM across cancer types has been validated by multiple studies. In those trials, SignateraTM demonstrated predictive values such as1-4:

“Diagnosis of diseases such as cancer are complex and unique to each patient,” said Lawrence Mahan, SVP of Commercial, Business and Consumer Markets for LifeLabs. “It’s important to us at LifeLabs that we continue to grow in a way that expands access to important health care services that supports Canadians. We’re excited to offer this groundbreaking and innovative test as a means to support patients and oncologists greater clarity in making precise clinical decisions regarding cancer treatment(s).”

SignateraTM testing involves two phases with pre-supplied collection kits. The first phase is an initial test that analyzes both a tumour tissue and blood sample, and the second phase involves subsequent blood tests on an as-needed basis. It is a safe, non-invasive way to monitor ctDNA levels to help physicians understand treatment efficacy and detect relapse without the inconvenience of repeated tissue biopsies and/or imaging.
