New HIV+ diagnosis. What is a CMV IGG positive test and what does it mean?
Response from Dr. Holodniy
It refers to a positive antibody test to cytomegalovirus (CMV), which is a member of the herpes virus family. Almost all people in the US have been exposed to CMV, usually as children and are antibody positive. People are "chronically" infected, but the virus is dormant, unless there is a loss of immune function like AIDS or transplant patients on immunosuppressive drugs. Then the virus can cause active infection.
