Negative COVID-19 Antibody Test Results
A negative result on a COVID-19 Antibody Test means that your results suggest that you were not exposed to SARS-CoV-2 (COVID-19) or, if you were exposed, then you 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 antibodies to be detected by the test yet. If that is the case, retesting may be needed.
Because this test only determines whether you have antibodies against SARS-CoV-2 (COVID-19), contact your employer about your next steps. Follow your employer’s guidance regarding ways to protect others from being infected with COVID-19.
The decision to return to work should be determined by you and your employer based on a number of factors, including symptoms and ongoing risk of spreading the virus to others.
Because your test came back negative, if you become exposed to COVID-19, monitor for symptoms of COVID-19. If you develop symptoms, contact your employer right away to decide on next steps. If you develop severe or concerning symptoms, seek medical attention right away.
Be sure to continue to follow federal, state, and local government guidance regarding social distancing and COVID-19 safety precautions.

This test has not been approved by the FDA.
Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals.
Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status.
Positive results may be due to past or present infection with non-SARS-CoV-2 coronavirus strains, such as coronavirus HKU1, NL63, OC43, or 229E.
