Serological IgM / IgG antibody test for COVID-19

This blood test checks for the presence of IgM and IgG antibodies resulting from past or recent exposure to COVID-19. To date, the scientific community still knows very little about immunity to COVID-19 and there is currently no test to ensure that the presence of antibodies confers protective immunity. This is not a screening test for active infection with COVID-19.

If you have COVID-19-like symptoms, it is recommended that you wait at least 14 days after their onset to do a serological test for COVID-19.

What forms do the results of the serological IgM / IgG antibody test for COVID-19 test take?

A positive result: indicates that anti-SARS-CoV-2 IgM and/or IgG antibodies were detected. This result suggests recent or past COVID-19 infection. The presence of antibodies to SARS-CoV-2 is not indicative of protection against SARS-CoV-2 infection.

A negative result: indicates that anti-SARS-CoV-2 IgM and/or IgG antibodies were not detected in your sample. A negative result does not rule out SARS-CoV-2 infection and may be due to sampling too soon after infection or in an immunosuppressed patient.
