Find out if the SARS-CoV-2 vaccination is effective

The Vaccine Antibody Test is a qualitative rapid test that checks whether the body has produced neutralizing antibodies to the SARS-CoV-2 virus after vaccination.

Neutralizing antibodies play an important role in the development of the corona vaccine. Administering the vaccine triggers the immune system to produce neutralizing antibodies. These are the antibodies which prevent SARS-CoV-2 virus particles from entering healthy cells and inhibit the virus particles to multiply and causing a serious infection.

The SARS-CoV-2 Vaccine Antibody Test kit detects neutralizing antibodies focused on the spike protein (RBD): the neutralizing antibodies produced by administration of COVID-19 vaccines such as Pfizer, Moderna, Astra- Zeneca and the Janssen vaccine.

Within 15 to 20 minutes, the SARS-CoV-2 Vaccine Antibody Test kit measures the presence of neutralizing SARS-CoV-2 antibodies in the blood. The test is 96.1% accurate.

A positive test result confirms the vaccination was effective.

When can the vaccine antibody test be used?

The SARS-CoV-2 Vaccine Antibody Test works from 3 weeks after vaccination, as it takes a few weeks for the immune system to produce enough antibodies to fight the virus. The test already works after the first vaccination.

The vaccine antibody test is specifically designed to check whether a vaccination has had the desired effect. For this purpose, always choose an antibody test that detects the 2019-nCoV neutralizing antibodies in the tested sample.

If neutralizing antibodies are found in the blood sample, the SARS-CoV-2 Vaccine Antibody Test will show this within 15 to 20 minutes.

People who have been vaccinated with a COVID-19 vaccine (the test can be taken after the first dose, after the second, or after the first as well as the second dose);
People who have not been vaccinated with a COVID-19 vaccine yet, but want to know if they have otherwise produced 2019-nCoV neutralizing antibodies;
People who have been infected with the SARS-CoV-2 virus and have more than two weeks ago recovered from COVID-19.

The test result can be a tool for your physician to make informed decisions regarding your health situation.

The SARS-CoV-2 Vaccine Antibody Test kit is for professional use only.

Please note: Test results should not be used as the only criterion for determining the presence of antibodies to the SARS-CoV-2 virus. Always discuss the test results with the appropriate medical practitioner.

A positive test result shows that neutralizing antibodies have been found in the blood sample. This is an indication that the vaccination is effective, and that the body has built up a certain immunity against COVID-19. Have you not been vaccinated (yet)? Then a positive test result means that you had a recent or past COVID-19 infection and that your body has produced neutralizing antibodies in response to the infection.

Please note: positive test results do not rule out (re) infection with the SARS-CoV-2 virus. Even after vaccination a person can become (re)infected. Therefore, follow government regulations at all times, keep sufficient distance, wear a mask, wash your hands often and continue to pay attention to symptoms.

A negative test result means that no or no measurable amount of neutralizing antibodies were found in the blood sample. This is an indication that the vaccination is not (yet) effective. It is possible that the body did not have enough time yet to produce sufficient neutralizing antibodies. If you were vaccinated against the SARS-CoV-2 coronavirus more than 3 weeks ago and you received a negative test result, we recommend you perform a second test. A second test gives a 99.95% accurate result. If you have a negative test result again, contact your physician.

Frequently Asked Questions

Why an antibody test to know if the vaccination is working?

Vaccines are designed to mimic the body's natural immune response to an infection. The natural immune response involves the production of antibodies and immune cells. These antibodies and immune cells specifically target the pathogen causing the infection. Antibodies are by far the easiest to measure, which is why antibodies are generally used to measure the immune response.

In the development of vaccines, antibodies play a key role. These are the neutralizing antibodies. Administering a vaccine triggers the immune system to produce these neutralizing antibodies. To check whether a vaccine works, it is necessary to see whether someone has produced those neutralizing antibodies. This can be done with an antibody test. However, the antibody test must specifically target neutralizing antibodies for that particular virus.

The SARS-CoV-2 Vaccine Antibody Test kit has the required CE marking and meets the requirements of the EU IVD (In-Vitro Diagnostics) guideline (98/79/EC).

What is the difference between neutralizing antibodies and binding antibodies?

Antibodies are part of our natural defence system. Antibodies can be divided into neutralizing antibodies and non-neutralizing antibodies. The latter are also called 'binding antibodies'. When the body is infected, for example with a virus, our immune system produces antibodies, which are released to fight the pathogen. ‘Binding antibodies’ and 'neutralizing antibodies' have a slightly different function. Binding antibodies bind to the pathogen (for example a virus) and alert the immune system, which then releases white blood cells to destroy the pathogen. Neutralizing antibodies work together with the binding antibodies. Neutralizing antibodies prevent the pathogen from infecting the body. They do so by inhibiting virus particles to enter healthy cells and preventing virus particles from multiplying and causing a serious infection.     

Neutralizing antibodies are the antibodies you need to achieve long-term immunity. That's why neutralizing antibodies play a central role in vaccine development. By administering a vaccine, the immune system is triggered to produce those neutralizing antibodies. The antibodies will then naturally recognize and fight the virus in the event of a possible new infection.

What is the difference between a vaccine test and the regular corona antibody test?

The vaccine antibody test is specifically designed to detect the presence of 2019-nCoV neutralizing antibodies in the blood sample. These are the antibodies that the body produces after vaccination against the SARS-CoV-2 coronavirus.

The SARS-CoV-2 Vaccine Antibody Test kit detects the antibodies targeting the spike protein: the neutralizing antibodies that are triggered by administration of COVID-19 vaccines like those from Pfizer, Moderna, Astra- Zeneca and Janssen.

When someone is infected with a virus, the immune system produces binding antibodies as well as neutralizing antibodies. Both binding and neutralizing antibodies provide protection against a new infection; however, neutralizing antibodies are the antibodies that provide long-term immunity.

A "regular" antibody test generally does not differentiate between binding and neutralizing antibodies. The test shows whether someone has produced antibodies, but not which ones. Therefore, the regular antibody test is primarily useful for finding out if someone is recovering from COVID-19 and has naturally developed antibodies against the SARS-CoV-2 virus. The vaccine antibodies test on the other hand, specifically looks at the neutralizing antibodies.

How long do neutralizing antibodies remain active in the blood?

How long neutralizing antibodies remain in the blood after infection with the SARS-CoV-2 virus varies from person to person. Studies show that this depends, among other things, on the severity of the infection and the personal situation of the individual. In some people, the number of antibodies shows a rapid decline after a few months. In others a slow decline was observed, but the quantities can also remain stable for a long time and in some cases even increase over time. How many antibodies one produces can also vary from person to person. Unfortunately, it is also not known yet how long an individual remains immune to COVID-19 after vaccination. This is currently being examined.

Please note: The SARS-CoV-2 Vaccine Antibody Test kit is a qualitative test and will not show how many neutralizing antibodies a person has produced. The test also does not indicate a specific level of immunity or protection against a (new) SARS-CoV-2 infection.

How accurate is the test?

The SARS-CoV-2 Vaccine Antibody Test kit has a sensitivity of 95.83% and a specificity of 96.43%.

Test results may show that you have neutralizing antibodies in your blood. However, the test does not indicate how many neutralizing antibodies were found in the blood sample. A positive result also does not mean that you can no longer be infected with the SARS-CoV-2 virus. A great deal of research is currently being done to find out more about the possibility of reinfection. For now, it appears that a person can be (re)infected even after vaccination. Though the presence of neutralizing antibodies in the blood seems to indicate that the duration and severity of the infection decrease, this has not yet been clearly determined. Therefore, follow government regulations at all times, keep your distance, wear a mask, wash your hands often and continue to pay attention to symptoms.
