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.
  • Neutralizing antibodies: detection of the function of antibodies against COVID-19.
  • SARS-CoV-2 nucleocapsid protein antibody: evidence of previous infection without evidence of vaccination.
  • SARS-CoV-2 specific T cell assay : MEssurement of cellular immunity.

We draw your blood for the test in our practice rooms in Munich (Briennerstraße 11) and have the antibodies determined quantitatively and the test for neutralizing antibodies 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.

The neutralizing antibody test can be used to assess the function of the antibodies present against COVID-19.

Detection of nucleocapsid protein antibody allows detection of previous disease even in vaccinated individuals, as this protein is not present in vaccination.

Testing for specific T cells can be used to visualize the immune response to COVID-19 at the cellular level, even when antibodies may not be present.

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. In case of 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 safety of the test depends on the so-called pre-test probability, i.e. how likely an infection was in advance. In the meantime, it can be assumed with a high degree of certainty that persons with a positive antibody test had previously contracted COVID-19 or had 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, determination by direct PCR detection of the SARS-CoVs pathogen in a throat swab should be performed.

Since antibodies can only be detected with a delay after the onset of symptoms, we recommend that antibody testing be carried out from four weeks after possible contact with an infected 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.

The costs have not yet been covered by the statutory health insurance funds. The cost of the test includes consultation and blood collection:

IgG antibodies: €50.40
Neutralizing antibodies: €69.73
IgG+neutralizing antibodies: €80.13

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.

In coronal testing, ELISA is currently probably the most accurate test procedure commercially available in laboratories. 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 the ELISA test procedure.
