US regulators may soon clear blood-based biomarker tests for colorectal cancer (CRC), expanding potential options for patients seeking more convenient forms of screening.
Most recently, Guardant Health, Inc, announced the completion of its US premarket approval application for its Shield blood test to screen for CRC. Approval by the US Food and Drug Administration (FDA) would position Guardant to later secure Medicare coverage for its test.
Rival companies, including CellMax Life, Freenome, and Exact Sciences, which already offers the stool-based Cologuard product, are pursuing similar paths in their development of blood tests for CRC.
