LETTER from SUSAN HUGHSON

What Is An Antibody?

What Does It Tell Us?

To the Editor:

In his column of April 23-24 regarding coronavirus testing, Dr. Richard Sternberg refers to “an antibody test which would tell us who is immune to the virus.”

It is my understanding that the antibody test indicates an individual’s direct exposure to the virus, with or without symptoms.

Whether the presence of these antibodies confers immunity, and for how long, has yet to be determined.
