Antibody measurement with laboratory test before 3rd vaccination or after infection – information

Before 3rd vaccination, after vaccination or if you have had the coronavirus, we recommend an antibody test from intravenous blood to determine the amount of antibody in your body, from which protection against coronavirus can be inferred.

The antibody concentration is given in the WHO International Standard Units  of Measurement:
BAU/ml = Binding Antibody Units per ml

We recommend this antibody test (Centaur test) in the following cases:

  • Measure antibody levels regularly and if they drop, consider a 3rd vaccination.
  • After the administration of the coronavirus vaccine(s), by which time full immunity is expected to have developed. Antibody measurement will show whether the appropriate level of antibodies against the SARS-CoV2 virus has been established. Sampling is recommended taking into account the immunity period for different vaccines.
  • If you have had a positive PCR-confirmed coronavirus infection – so you can find out how much protection you have.
  • If you think you may have had the disease in the past, but this is not confirmed by a PCR test – antibody testing can be used to confirm whether you have had the infection, so the result can be used to apply for the immunity certificate according to 60/2021. (II. 12.) Government Decree. More information on this can be found below.

It can measure infection and immune response after each vaccination. (e.g. Pfizer, Moderna, Szputnyik, Sinopharm, AstraZeneca, Johnson&Johnson, CoviShield, CanSino, CureVac)

Laboratory test for the Immunity Certificate – information

This laboratory test shows the amount of antibody both after infection and after each vaccination.

Using an antibody test for protection against venous blood (also called a serological test, or Centaur test), the laboratory tests for the presence of an S-RBD IgG antibody against the SARS-CoV-2 virus produced by the body. It should not be confused with the rapid serological test, which does not give a quantitative result and cannot be used to apply for a security certificate.

In contrast to rapid tests,this examination can be used to determine the amount of antibody, from which protection against coronavirus can be inferred. If the result is positive, the laboratory result can be used for the immunity certificate.

The antibody concentration is given in the WHO International Standard Units  of Measurement:
BAU/ml = Binding Antibody Units per ml

In case of a positive result, you can apply electronically with the Laboratory test for Immunity Certificate (on an electronic form standardized by the government offices) or in person at any government office. The positive result confirms that the antibody against the coronavirus can be detected in the body, so the result can be used to apply for the immunity certificate according to 60/2021. (II. 12.) Government Decree.
.

In the event of a negative result, your body does not have a detectable amount of antibodies to the coronavirus.

After the first positive result, it is advisable to repeat this serological test every month to see the change in the amount of antibodies.
