Unilabs Denmark offers testing for antibodies against Covid-19/ SARS-CoV-2 (serological analysis from serum or plasma).

Why test for antibodies?

The SARS-CoV-2 (Covid-19) antibody test informs if a person has developed antibodies to Covid-19 as a consequence of an earlier infection.

Unilabs recommends determining immunoglobulin G (IgG).

IgG antibodies against Covid-19 are detectable 2-4 weeks after infection and can identify people who have already been infected, but may have showed only mild or no symptoms, and have potentially developed immunity to further infections.

Important: The presence of IgG antibodies against SARS-CoV-2 does not ensure immunity to further infections. These investigations are currently underway.

The test has been clinically validated in a professional and accredited laboratory at our Unilabs premises in Copenhagen, and will be performed on a blood sample with a Euroimmun ELISA kit. The Euroimmun kit has been demonstrated to  Specificity of 98,5% and a Sensitivity 98% 4 weeks after symptom onset or a positive PCR test for SARS-CoV-2.
The presence of antibodies against SARS-CoV-2 does not ensure or protection against reinfection. Studies are ongoing and confirmation of immunity or the immune status is currently not an indication for antibody testing.
