Epstein-Barr virus test

During this test, a blood sample is sent to a lab, where a lab specialist looks for antibodies to the Epstein-Barr virus (EBV), which is a member of the herpes virus family. In the first stages of illness, little antibody may be detected. For this reason, serology tests are often repeated in 10 days to two or more weeks.

The test is done to detect infection with the EBV. The EBV antibody test will detect not only a recent infection, but also one that occurred in the past. It can be used to tell the difference between a recent or previous infection.

The EBV is considered a risk factor for developing other conditions, including mononucleosis and some forms of cancer.
