About the COVID-19 Antibody Test

This test may detect antibodies produced if you were infected by COVID-19. It does not detect the spike antibodies produced by the vaccines currently available.

What is a semi-quantitative COVID-19 antibody test?

This test checks for antibodies to COVID-19. If you’ve been exposed to COVID-19, your body produces antibodies as part of your immune response. The test provides a numerical value that indicates whether or not you may have antibodies to COVID-19.

IgG antibodies are believed to appear 3-4 weeks after infection.

When IgG antibodies are present, it often indicates a past infection but does not exclude recently infected patients who are still contagious. It is unknown how long  IgG antibodies to SARS-CoV-2 will remain present in the body after infection and if they confer immunity to infection.

According to the Centers for Disease Control and Prevention, “Serologic test results have limitations that make them less than ideal tools for diagnosing people who are sick.”
