On March 6, 2018, the U.S. Food and Drug Administration (FDA) authorized the Personal Genome Service Genetic Health Risk (GHR) Report for BRCA1/BRCA2 (Selected Variants). It is the first direct-to-consumer (DTC) test to report on three specific BRCA1/BRCA2 breast cancer gene mutations that are most common in people of Ashkenazi (Eastern European) Jewish descent. These three mutations, however, are not the most common BRCA1/BRCA2 mutations in the general population.
The test analyzes DNA collected from a self-collected saliva sample, and the report describes if a woman is at increased risk of developing breast and ovarian cancer, and if a man is at increased risk of developing breast cancer or may be at increased risk of developing prostate cancer. The test only detects three out of more than 1,000 known BRCA mutations. This means a negative result does not rule out the possibility that an individual carries other BRCA mutations that increase cancer risk.
The FDA press release states:
"Consumers and healthcare professionals should not use the test results to determine any treatments, including anti-hormone therapies and prophylactic removal of the breasts or ovaries. Such decisions require confirmatory testing and genetic counseling. The test also does not provide information on a person’s overall risk of developing any type of cancer. The use of the test carries significant risks if individuals use the test results without consulting a physician or genetic counselor."

Understanding both the benefits to be had from offering BsAb therapy to its community and the scope of this undertaking, Vanderbilt-Ingram Cancer Center took a novel approach with its APP-led BsAb step-up dosing clinic, which won the program a 2026 ACCC Innovator Award.
