COVID Antibody Testing

At this time, Discover Health physicians are offering IgM and IgG antibody testing for SARS-CoV-2, the virus that causes COVID-19. We are using a blood test (ELISA) developed and validated by Stanford scientists and physicians to detect antibodies to a specific part of the COVID virus (SARS-CoV-2 receptor binding domain [RBD]). The FDA has been notified, but this test has not been reviewed nor approved by the FDA. Because this test has not been reviewed/approved, it is considered an experimental test. Results from the antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection. A negative test result does not rule out SARS-CoV-2 infection. A positive test result may be due to past or present infection with other strains of coronavirus, such as coronavirus HKU1, NL63, OC43, or 229E. In case of a positive test, follow-up testing with a molecular diagnostic test may be considered to rule out active infection. In other words, this antibody test results should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status. 

In terms of logistics, here’s what you need to know:
  1. Testing will be available on Mondays and Wednesdays from 8:30 am-12:00 pm through in-office appointments only. There is not currently a test-at-home option available. 
  2. Testing is available to asymptomatic adults and adolescents only -  no signs of illness for at least one week. We are not offering antibody testing for children until there is a finger-prick option available.
  3. Testing will be available to Discover Health members only, on a first-come first-serve basis, until we run out of supplies. 
  4. You must bring a mask with you and wear it during the entire time you are at the office. Only the individual(s) with the appointment will be allowed into the office.
  5. Turnaround time for testing is currently 3-5 days.
We know that many people are interested in antibody testing and will continue to offer this service for as long as we can. Please contact the office directly 415-732-7029 if you want to set up an appointment.
