The antibody test can be used to detect an infection that has been passed through, such as corona, as the immune system produces specific antibodies: IgM antibodies are positively detected after only a few days, IgG antibodies after several weeks.
As the antibodies can only be detected with a delay after the onset of symptoms, we recommend that you have your antibodies determined at the earliest two weeks after the onset of symptoms and four weeks after any contact with a person with the disease.
For the test, a venous blood sample is taken and the evaluation takes place within 24 hours in a certified laboratory.
This is an ELISA test (Enzyme-Linked ImmunoSorbent Assay). It is based on an enzymatic colour reaction with which antibodies can be detected in the blood.
Good to know: An antibody test is a self-pay service (IGeL), i.e. the costs are not covered by the statutory health insurance.
