NADAL® COVID-19 S1-NAb Test
Check if your vaccination was successful

For the qualitative detection of potentially neutralising antibodies against SARS-CoV-2 in human whole blood, serum or plasma samples.

The NADAL® COVID-19 S1-NAb Test serves as an aid in determining whether an immune response to the S1 subunit of the SARS-CoV-2 spike protein has occurred. Antibodies can be detected against vaccines that trigger an immune response against the S1 subunit of the spike protein, such as those from BioNTech/Pfizer, Moderna®, AstraZeneca, Johnson&Johnson and Sinovac Life Sciences.

The test procedure is not automated and requires no special training or qualifications.

The NADAL® COVID-19 S1-NAb Test is intended for professional use.

Neutralising antibodies against SARS-CoV-2

The effectiveness of vaccines against coronavirus SARS-CoV-2 lies between 65 % and 95 %.* The detection of neutralising antibodies can determine whether a vaccine has been successful. Following a vaccination or an infection with coronavirus, various antibodies are produced by the immune system. However, only some of the antibodies formed have a neutralising effect, i.e. they prevent the virus from entering the host cell. Neutralising antibodies block the spike protein on the surface of the virus, preventing it from binding to the host cell's ACE2 receptors and thus protecting against a severe course of infection with COVID-19.

These potentially neutralising antibodies against the S1 subunit of the SARS-CoV-2 spike protein can be detected using a rapid test.
