When Should You Test For Antibodies To Coronavirus?

It's vital that you wait at least 14 days from the onset of symptoms, or from exposure to the virus.

This is because there is a 'window period' during which a process called seroconversion develops antibodies to reliably detectable levels.

Since many people experience few - or even no symptoms at all - from COVID-19 infection, you can still take this test if you have not had symptoms. Again, antibodies will only be detected if you were infected at least 14 days ago.

Note that people who are immunocompromised may take longer to develop antibodies to Coronavirus infections.
