BRCA Testing Laboratory Resources

This information is tailored toward breast and ovarian cancer susceptibility genetic testing and is not intended to reflect all labs that offer genetic testing; information is subject to change. Please refer to for an overview on the genetics of breast and gynecological cancers.

  • Most commercial labs offer options of single gene testing (BRCA1/2 only) as well as multigene panel testing options.
  • Patients with active hematologic malignancy or prior allogeneic stem cell transplant cannot use blood or saliva (buccal) samples for genetic testing. Testing for these patients requires DNA from fibroblast samples via skin punch and cell culture.
  • Providers are responsible for ensuring informed consent from patients; informed consent documents are available on most lab websites. Labs may request patient and/or provider signature (or e-signature) to indicate informed consent has been obtained.

Insurance-Specific Requirements & Reporting
Medicare, Aetna, Cigna, UHC: These insurances each have specific BRCA testing criteria for insurance coverage.

  • Cigna has a specific precertification requirement for individuals to receive pre-testing genetic counseling from a genetics provider meeting Cigna standards.
  • United Health Care (UHC): Some UHC insurances require provider to submit pre-authorization via UHC portal
