My COVID-19 antibody test was negative, but I previously tested positive for COVID-19 or was exposed. Is my result incorrect?

Getting an antibody test too soon after being infected may cause a false-negative result. It usually takes around 1 to 3 weeks after being infected with COVID-19 for your body to produce enough antibodies to be detected in the blood. Some people may take even longer to develop antibodies or may not develop enough antibodies to be detected by the test.

It is recommended that you contact your healthcare provider or local health department to see if retesting is needed.
