About this test
Myriad myChoice CDx is an FDA-approved, NGS-based companion diagnostic that analyzes DNA from FFPE tumor tissue to detect pathogenic BRCA1/2 variants and calculate a genomic instability score reflecting homologous recombination deficiency (HRD). Results classify tumors as HRD-positive or HRD-negative, helping identify patients who may benefit from DNA damage response–targeted treatment strategies.
