Cytomegalovirus IgG
Cytomegalovirus (CMV) IgG measures antibodies that develop after exposure to the cytomegalovirus, a common herpes-family virus that most people encounter at some point in life and that usually stays in the body in a dormant state.
Why it matters: A positive CMV IgG indicates prior exposure. The result is most relevant before pregnancy, before organ transplant, or when immune-status questions arise — it provides context, not an action plan on its own.
