CORONATEST IN MUNICH: ANTI-BODY IgG and neutralizing antibodies

DR. FRÜHWEIN PARTNER

We are also available as a testing center for antibodies against the coronavirus (SARS-CoV-2) in Munich:

  • SARS-CoV-2 spike protein IgG antibody: evidence of previous infection or vaccination.
  • SARS-CoV-2 nucleocapsid protein antibody: evidence of previous infection without evidence of vaccination.

We take your blood for the test in our practice in Munich (Briennerstraße 11) and have the antibodies quantitatively determined and the test for neutralizing antibodies carried out in our certified partner laboratory. As specialists in tropical infectious diseases, we have a lot of experience with various testing procedures and will be happy to advise you. Antibody detection is an important diagnostic tool to retrospectively detect SARS-CoV-2 infection or to exclude a corresponding infection in the past. Antibodies after vaccination can also be determined with this test. Determination of IgG antibodies provides quantitative evidence of the presence of antibodies to Sars-COV-2. Detection of nucleocapsid protein antibody allows detection of previous disease even in vaccinated individuals, as this protein is not present in vaccination. The test is not suitable for acute diagnostics. If you are acutely ill and want to be tested, you should take a smear test.

Questions and answers

on the coronavirus (COVID-2019)

No. If you have acute symptoms, please call the practice or make an appointment for a smear test/PCR.

Even though the sensitivity and specificity of the test are very high, the reliability of the test depends on the so-called pre-test probability, i.e. how likely an infection was beforehand. It can now be assumed with a high degree of certainty that people with a positive antibody test had previously contracted COVID-19 or been vaccinated.

As a result of SARS-CoV-2 infection, various antibodies are produced as an immune response. IgM antibodies become positive after only a few days, IgG antibodies after several weeks. Only part of it has a protective function. This can be measured as neutralizing antibodies.

No. The test is not suitable for the detection of an acute infection. In this case, the SARS-CoVs pathogen should be determined by direct PCR detection in a throat swab.

As antibodies can only be detected with a delay after the onset of symptoms, we recommend carrying out the antibody test from four weeks after possible contact with a sick person and at the earliest two weeks after the onset of symptoms.

To date, it is believed that having been through infection provides some protection against re-infection by SARS-CoV-2. However, how long and how safe this protection is needs to be further researched. High IgG antibodies with a high proportion of neutralizing antibodies indicate good protection.

You will normally receive the result within 1 to 2 days.

Enzyme-Linked ImmunoSorbent Assay (ELISA ) refers to an antibody-based detection method. It is based on an enzymatic color reaction with which antibodies can be detected in the blood. Antibodies are produced by the immune system in response to a pathogen. We cooperate with a certified and accredited laboratory in Munich, which also accompanies the large antibody study in Munich with this antibody test.

The ELISA is probably the most accurate test method currently commercially available in laboratories for corona testing. It is probably somewhat more accurate than the rapid test, which is usually performed as an immunochromatographic lateral flow test. However, there is a lack of sufficient data for a final assessment of the respective test procedures. In our practice in Munich, we therefore offer you the ELISA test procedure.
