A biopsy can provide crucial information that aids diagnosis, prognosis, and prediction of response to treatment. However, it can be difficult to obtain enough tissue from the biopsy for multiple tests; and in some cases, it may not be possible for patients to undergo standard tissue biopsy procedures due to their health or the location of the tumour.1
Liquid biopsy, a non-invasive sampling alternative, can help overcome the challenges associated with obtaining tumour tissue samples. It allows labs to test peripheral blood obtained from the patient with a simple blood draw.2
