COVID-19 Antibody Testing
April 28, 2020 | by Trong Tony Trinh MD, MPH

The Polyclinic offers the Abbott SARS-CoV-2 IgG antibody blood test that has been authorized by the Federal Drug Administration (FDA) under the Emergency Use Authorization and verified by Abbott Labs and UW Medicine as highly accurate and reliable. Test results are typically available via MyChart in 24 hours. As required, we will share your results, positive or negative, with King County Public Health.

Patients should talk with their provider about the benefits and limitations of this test.

What can this test do?

  • This test is intended ONLY to confirm prior exposure or infection due to COVID-19 (e.g if exposure or infection occurred approximately >2 weeks in the past)
  • This test helps understand background rates of exposure to COVID-19 in the community
  • This test helps public health authorities better determine prevalence

What can’t this test do?

  • This test does NOT test immunity.
  • This test does NOT determine protection against COVID-19 re-infection.
  • This test does NOT diagnose active COVID-19 infection.
  • This test does NOT prove that someone is NOT infectious.
  • This test does NOT replace standard effective infection control practices – social distancing, cough hygiene, hand hygiene, minimizing contact with vulnerable populations.
  • The test has only been authorized by the FDA under emergency use authorization (EUA) and thus lacks robust validation studies.

What does it mean if I test positive?

It means that it is likely you were exposed or were infected with the COVID-19 virus over two weeks ago.

What does it mean if I test negative?

It means that it is unlikely you were exposed or infected with the COVID-19 virus over two weeks ago.

Talk with your primary care provider if you are interested in getting tested. Blood draws for antibody testing are performed at The Polyclinic Madison Center lab.
