What does it mean to test positive to a antibody/antigen test?

Answer 1

To test positive to an antigen test means that you are currently infected with a certain antigen/illness. To test positive to an antibody test means that you are either or have been in the past been infected by a certain antigen/illness.

An antigen is a foreign substance that enters the human body; the body uses antibodies as a defense against these invaders.

If you have a positive antigen test, it indicates that you are presently infected with that particular antigen or disease.

If you have a positive antibody test, it indicates that you are currently infected with a particular antigen or disease, or that you have been previously.
