COVID antibody test accuracy: You can’t rely on antibody testing to predict immunity
Experts still need answers when it comes to determining what the results of an antibody test entail and other factors might play in these.
There are many versions and variations of antibody tests that are popular in the market right now, and all originate from various manufacturers. However, research suggests that you should not rely on antibody testing alone when trying to determine if a person who previously had COVID-19 can sustain their immunity against it.
There is currently a lack of research that covers whether the presence of antibodies truly means complete immunity, or how long it would last.
COVID antibody test accuracy: Can you test vaccine effectiveness by investigating antibodies?
Some people believe that an antibody test can be used in detecting the actual presence of of COVID-19. This is not true. According to the FDA, antibody tests can have negative results, even in infected people. You can also get a false negative with your antibody results.
On the other hand, a positive antibody result can be helpful in identifying if you may have had an infection before. However more research is needed on antibody testing in those who have received full vaccination against SARS-Cov-2.
There are many available serology tests in the market. However, none have been evaluated in terms of assessing the the immune responses to a COVID-19 vaccine.
