How do COVID-19 antibody tests differ from diagnostic tests?

With all the debate regarding coronavirus infection 2019 (COVID-19) tests and testing, it’s no surprise that there’s some confusion over the tests and how they differ. The tests for antibodies are usually conducted to determine if you’ve had COVID-19 before and have antibodies against the COVID-19 virus.

The sample is then examined to determine if you’ve developed antibodies to COVID-19, a virus that causes the disease. The immune system makes antibodies — proteins that are essential to fight and eliminate the virus.

If the results of tests show you have antibodies it could mean that you were infected by the COVID-19 virus previously or are immune after having been vaccinated. It could also mean that you have some form of immunity.

Another advantage of testing for antibodies is that patients who’ve been cured of COVID-19 could be able to donate plasma, which is part that is found in their blood. The plasma can serve as a treatment for other patients suffering from severe illnesses and increase the capacity to fight the virus.
