There is still much uncertainty about the value and use of testing for antibodies related to the new coronavirus. The CDC is still studying and determining the exact benefits to antibody testing. The antibody test provides an estimate of how many people have been infected in order to determine how many in the public remain at risk. This may help with trends and future predictions about the progression of the pandemic. “Having antibodies to the virus does not guarantee a person will not contract it again. We just don’t know enough about this virus yet,” says Dr. Sharieff.
