Preventive Genomics Clinic

The Preventive Genomics Clinic helps people harness the power of genomic screening to learn more about their health and future disease risk. UCSF is one of the few academic medical centers in the nation to offer this service directly to the public. Unlike direct-to-consumer genetic testing companies, we use the most comprehensive genomic tests currently available. These tests, which can only be ordered by physicians, sample more of your DNA and can reveal more about your health needs.

We also provide up-to-date information about the benefits and limitations of testing, along with one-on-one interpretation of your results and counseling by trained geneticists. Should your results raise concerns about your health, we can refer you to the right specialist to get the monitoring and care you need.

We offer the following tests:

  • Carrier screening, or screening for genetic mutations that could be passed on to your child
  • Cancer and heart disease risk screening
  • Pharmacogenetic testing, or testing for how your genes may affect your response to medications
  • Broad genome screening that combines all of the above tests into one

If you've already had genetic testing at another clinic or through a direct-to-consumer company such as 23andMe, we are happy to answer health questions about your results and to discuss other tests that are available only through a physician.

We will try to obtain authorization for your clinic visit if your insurance carrier requires it; however, we cannot guarantee coverage. Self-pay rates are available. Because genomic screening tests are considered elective and do not diagnose or treat any active condition, they are rarely covered by insurance. Out-of-pocket costs for testing range from about $250 to several thousand dollars.
