Despite COVID-19 vaccinations having high efficacy of 70-95 percent, you may wish to know more about your individual response to the vaccine.
Sloane Street Testing is now able to test an important part of your immune response to vaccination by measuring antibodies to the COVID-19 spike protein. We use the highly accurate Roche Elecsys test.*
Older antibody tests such as the Abbott and cassette antibody tests that give an immediate answer, do not detect a response to vaccination.
