“Within a period of a week or so, we’re going to have a rather large number of tests that are available,” Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases, said on CNN’s “New Day” Friday morning.

Having antibodies to the coronavirus could mean someone is protected from getting re-infected, making such tests important for medical workers and others on the front lines fighting the pandemic.

“If their antibody test is positive, one can formulate strategies about whether or not they would be at risk or vulnerable to getting re-infected,” Fauci explained.
