Cytomegalovirus IgG

Infection DiagnosticsImmunity & InflammationBlood

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.

What is 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.

What might a high or low Cytomegalovirus IgG mean?

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.

What is the typical reference range for Cytomegalovirus IgG?

The general-population reference range shown here is 0 – 12 IU/mL. Reference ranges describe the general population and are not a personal target — discuss your results with your physician.
