What is FoundationOne CDx?
FoundationOne CDx is the first FDA-approved broad companion diagnostic (CDx) that is clinically and analytically validated for solid tumors. The test is designed to provide physicians with clinically actionable information — both to consider appropriate therapies for patients and understand results with evidence of resistance — based on the individual genomic profile of each patient’s cancer. Every test result includes microsatellite instability (MSI) and tumor mutational burden (TMB) to help inform immunotherapy decisions. You can also order PD-L1 immunohistochemistry (IHC) testing† to help inform your therapy decision. FoundationOne CDx has national coverage for qualifying Medicare and Medicare Advantage patients across all solid tumors.‡
