Types of COVID-19 antibody tests

Hi everyone! 

In this post, I will go over in very short the different types of  COVID-19 antibody tests.

COVID-19 spike protein antibody test can detect antibodies from a prior or recent infection, regardless of whether symptoms were present. Positive results may also occur after a COVID-19 vaccination.*

Nucleocapsid antibody test can only detect antibodies from a prior or recent infection.

Neutralizing antibody test can be used to assess the capacity of antibodies in patient plasma to inhibit the SARS-CoV-2 virus. It is used for the screening of convalescent plasma for prophylactic and therapeutic use. 

*Antibody testing is not currently recommended to assess for immunity to COVID-19 following COVID-19 vaccination or to assess the need for vaccination in an unvaccinated person.
