COVID-19 Antibody Testing Q & A

What is COVID-19 antibody testing?

The antibody test detects antibodies that indicate past COVID-19 exposure. If you were previously exposed to COVID-19, you may potentially have some immunity. This test can tell you if you’ve been exposed to the virus with around 99% accuracy. 

With a COVID-19 antibody test, the skilled laboratory team performs your test onsite in the sterile and safe Sellwood Medical Clinic facility. You’ll get results within about 15 minutes.

Your experienced care provider performs a quick finger prick to get a drop of blood, and then you can wait for your results if you wish.

Unlike a COVID-19 test, the antibody test doesn't detect the virus. It essentially verifies whether your immune system previously fought the virus.

How do I get COVID-19 antibody testing?
A physician’s testing order is required before testing can be performed. Sellwood Medical Clinic providers can provide insured in-network patients with a testing order, at no cost.

COVID-19 testing must be done at the onsite lab. You can only receive antibody testing if you have been asymptomatic for 10 days.

This is not a test for people displaying symptoms. You must wait until your symptoms subside for 10 days and then you can receive a testing order.

When can COVID-19 testing detect exposure?

Antibodies don’t appear for 1-3 weeks after exposure to the virus. In some people, it takes longer to develop antibodies, and others never develop them at all. An antibody test today won’t tell you whether you were around someone with COVID-19 yesterday.

Does a positive antibody test mean I have COVID-19?

No. A positive antibody test simply means that you were exposed to the virus and that you have antibodies that fought the COVID-19 virus previously.

Does a positive antibody test mean I'm immune to COVID-19?

No, a positive antibody test doesn’t necessarily mean that you’re immune to COVID-19. Research is still ongoing, but at this time experts say that a positive antibody test doesn’t equal immunity. A positive antibody test is a good way to know whether you were exposed to the virus, though.

This means that even if you have a positive antibody test, it’s still important to maintain all the self-protection measures recommended by the Oregon Health Authority and the CDC.

What if I have a positive antibody test and COVID-19 symptoms?

If you have a positive antibody test and COVID-19 symptoms, your Sellwood Medical Clinic provider can perform an exam to determine whether you need COVID-19 viral testing. This viral test requires a swab from your inner nose or some other type of respiratory sample.


If you have a negative antibody test but have COVID-19 symptoms, you may still need a viral test to determine whether you have the virus.


If you or anyone in your family has COVID-19 symptoms or suspects exposure to the virus, reach out to Sellwood Medical Clinic for guidance. Call the office or use online scheduling to book a telehealth care visit today.
