Check your immune system’s response to Covid-19 vaccination, as well as any past infection, with this home test.
This do-it-yourself home test uses a finger-prick blood sample to check the level of your immune system’s response to Covid-19. It determines how your body has responded to the Covid-19 vaccine or infection.
This test was newly developed (January 2021) to assess individuals’ immune status using ‘a quantitative measurement of IgG antibodies against the spike receptor-binding domain (RBD) of SARS-CoV-2.’
This test detects if your immune system has formed IgG antibodies after being vaccinated or being naturally infected by Covid-19. You are given a quantitative measure of your immune system’s response (levels ranging from 0-80,000 AU/ml).
IgG levels have been observed to rapidly decrease in the months following an infection. This test can help monitor your IgG levels over time, confirming whether your levels have come down to an acceptable measure that may indicate immunity.
As part of recent proposals, countries like Greece, Cyprus, and Portugal have discussed, including this antibody test for ‘Vaccine Passports.’
