Test Results

If I get tested, what will the results tell me?

Your test results may help identify if you were exposed to the virus that causes COVID-19 and, if so, whether or not your body has developed antibodies. Although having antibodies usually gives immunity from further infection, there is not enough evidence at this time to suggest that people who have antibodies against SARS-CoV-2, the virus that causes COVID-19, are protected against future infections from the virus. Results from this test also will not provide information on whether you can spread the virus to others and is not used as a basis for diagnosis.

A variety of factors can impact the results from the antibody test including the time the test was taken after experiencing COVID-19 symptoms, the absence of or time since exposure to the virus, or the lack of an adequate immune response, which can be due to conditions or treatments that suppress immune function.

Additionally, serology (antibody) tests may detect IgG antibodies from previous exposure to coronaviruses other than SARS-CoV-2 (COVID-19). This can cause a false positive result. 

Your results will be provided to you through our secure online portal to view or print. Your results will be reported to public health authorities where required by law.
