If you’ve had COVID-19 in the past, or suspect that you have, you may want to get an antibody test, which tests your blood serum to check for your body’s response to an infection. If you decide to proceed with an antibody test, make sure the test is authorized for FDA emergency use and speak with your doctor about the results. If your antibody test is negative, you probably were not infected with the SARS-CoV-2 virus in the past. If you test positive and have no symptoms of COVID-19, you likely were infected with SARS-CoV-2, especially if you had common COVID-19 symptoms in the past.
Rules governing which tests can be given and who can take them vary from state to state. It is wise to check with the department of public health in your state and also ask your doctor to determine if a test is appropriate for you. With reports of false positives growing, many physicians are recommending that patients wait until experts can better identify which tests are performing best.
