Result Interpretation
Viral testing (testing for current infection) Positive Most likely * you DO currently have an active COVID-19 infection and can give the virus to others.
Negative Most likely * you DO NOT currently have an active COVID-19 infection.
Antibody testing (testing for past infection with the virus) Positive You likely * have HAD a COVID-19 infection.
Negative You likely * NEVER HAD (or have not yet developed antibodies to) COVID-19 infection.
Both (antibody and viral testing) Viral Positive, Antibody Positive Most likely * you DO currently have an active COVID-19 infection and can give the virus to others.
Viral Positive, Antibody Negative Most likely * you DO currently have an active COVID-19 infection and can give the virus to others.
Viral Negative, Antibody Positive You likely * have HAD and RECOVERED FROM a COVID-19 infection.
Viral Negative, Antibody Negative You likely * have NEVER HAD a COVID-19 infection.

* No test is ever perfect. All tests occasionally result in false positive results (the test result should be negative because you DO NOT have COVID-19 but comes back positive) or false negative results (the test result should be positive because you DO have COVID-19, but comes back negative).
