Negative COVID-19 Antibody Test Results

A negative result means that your results suggest that you were not exposed to SARS-CoV-2 (COVID-19) or have not yet developed antibodies*​.

Negative COVID-19​ ​Antibody Results

Although not having antibodies suggests that you may still be able to get COVID-19, there is not enough evidence at this time to determine whether or not you are at risk. In the future, if you believe you are exposed to someone with COVID-19, testing with a molecular test (PCR) should be considered to check for active infection.

*If you were recently exposed to someone with COVID-19, or previously had symptoms of COVID-19, there is a possibility of a false negative. If you test too soon, your body may not have produced enough​ a​ntibodies to be detected by the test yet. If that is the case, retesting may be needed.
