There are two main types of antibody tests. Antibody tests require a blood sample and may also be known as serology tests. But there is still room for inaccuracies such as cross reactivity which is when a test picks up on common cold coronaviruses and mistakenly misidentifies them as COVID-19-related.

Antibody testing is not currently recommended to assess for immunity to COVID-19 following vaccination. There are currently too many unknowns to get an antibody test after a COVID-19 vaccine and expect any tangible takeaways even or especially if youre immunocompromised.
