CeGaT Enables Verification of Vaccination Effectiveness through Corona Antibody Test.

CeGaT’s CE-certified corona antibody test can be used to determine the effectiveness of vaccination against SARS-CoV-2.

The now-approved vaccines against the SARS-CoV-2 coronavirus cause the body to form specific antibodies against the spike protein of SARS-CoV-2. If the vaccination is effective, this leads to a clearly measurable increase in the blood’s so-called IgG antibodies. Individuals who have formed these specific antibodies against SARS-CoV-2 are considered to be immune. CeGaT’s corona antibody test detects whether a person has created IgG antibodies and thus has acquired vaccination protection.


A significant increase in IgG antibodies in the blood is required for successful vaccination protection. To check the vaccination’s effectiveness, CeGaT, therefore, recommends that the corona antibody test be performed no earlier than 7 days after the 2nd vaccination date.

The blood sample (serum) required for laboratory analysis can either be obtained free of charge at the CeGaT premises or by a medical doctor.

1. the CeGaT blood sampling site can be visited without an appointment Monday through Friday from 1:00 pm to 5:00 pm, and Saturday from 9:00 am to 1:00 pm. Blood collection is performed free of charge on-site by CeGaT’s medical staff.

2. Alternatively, the respective family doctor can perform the blood collection. The collection tubes required to achieve the blood collection can be ordered free of charge via the CeGaT web portal. Other blood collection tubes cannot be accepted for technical reasons. The collected sample can then either be sent to CeGaT by mail or handed in on-site.

CeGaT performs the testing for IgG antibodies in its in-house laboratory and sends the results within 1-3 days after receiving the sample. The laboratory is accredited according to CAP/CLIA and DIN EN ISO 15189 and thus meets the highest international quality standards.

The CeGaT blood collection kit contains:

  • CeGaT tubes for carrying out the blood collection procedure
  • all materials needed for the return shipment of the sample

PRICE EUR 25,- per sample sent in

The specificity of the corona antibody test:

The antibody test used by CeGaT is CE certified and approved by the FDA (Food and Drug Administration, USA). Several independent scientific comparative studies have confirmed the reliability of EUROIMMUN’s ELISA test and determined a specificity of 99.6 percent and a sensitivity of 94.4 percent. Thus, the corona antibody test performed by CeGaT guarantees the highest quality for the evaluation of vaccination effectiveness.
