Covid-19 I had corona?
Want to know if you've had Covid-19? Most reliable laboratory test. (COROA and COROG)
This test cannot be used to determine corona, the test is suitable for the detection of antibodies that the body forms after an acquired infection or vaccination.
Blood test for antibodies against Corona. EUROIMMUN antibodies against SARS-CoV-2 (ELISA) see the technical specificationshere
- COVID-19 IgG antibodies
- COVID-19 IgA Antigen
Why are no IgM antibodies measured?
One of our main goals in developing this ELISA was to distinguish it from the widespread coronaviruses. From experience with other coronaviruses, we know that IgM antibodies are primarily directed against the N protein of the virus. Unfortunately, the N protein is also described as cross-reactive due to the high homology (90%) between the different human pathogenic coronaviruses. For this reason, we selected the more specific S1 structural protein as the target antigen for this ELISA.
We know that infections with MERS-CoV and SARS-CoV-1 often do not produce specific IgG class antibodies until 10 days (or more) after the onset of symptoms.
With the Anti-SARS-CoV-2-ELISA IgA, we aim to enable sensitive detection of SARS-CoV-2 infection already in the early phase of the disease. Unfortunately, there are not many studies on the immune response to SARS-CoV-2 infections. However, we hope to be able to substantiate the added value of IgA antibody determination with data soon.
This test is CE-certified.

The sensitivity and specificity
From 10 days after the onset of symptoms, a sensitivity of 100% could be demonstrated with the combined use of the Anti-SARS-CoV-2-ELISA (IgA) and (IgG).
