Many COVID antibody tests will not detect the antibodies produced when you are vaccinated.
Our rapid COVID-19 antibody test does.
There are a number of different COVID proteins, including:
- Spike 1
- Spike 2
A previously infected person may produce antibodies to any or all of those proteins, any of which may provide a level of protection against re-infection.
The Moderna, Johnson & Johnson and Pfizer vaccines were developed to produce antibodies to the Spike proteins, and not the Nucleocapsid protein, so an antibody test that is focused solely on the Nucleocapsid protein antibodies is likely to be negative.
Many of the antibody tests on the market detect only the nucleocapsid antigen. Our rapid test detects both. We have tested a number of vaccinated (and not previously infected) individuals and confirmed it is reliable.
