Myriad is a pioneer in the field of companion diagnostics. In essence, companion diagnostics are tests being developed to identify patients most likely to benefit from specific treatments based on their own genetic makeup and biology. Companion diagnostics hold tremendous promise in the treatment of diseases such as cancer, rheumatoid arthritis and other autoimmune disorders, and diabetes.

Below are some of the promising companion diagnostics that Myriad has developed in collaboration with outside partners:

  • BRACAnalysis CDx® is a companion diagnostic test that uses a blood sample to identify germline mutations in the BRCA1 and BRCA2 genes
