CYTOMEGALO VIRUS(CMV)-IgG Detail

The CMV IgG test is a blood test used to determine if a person has been previously infected with Cytomegalovirus (CMV) by detecting IgG antibodies. CMV is a common virus that can cause asymptomatic infections in healthy individuals but may lead to serious complications in pregnant women, newborns, and immunocompromised patients (e.g., those with HIV/AIDS, transplant recipients).

A positive CMV IgG result indicates past exposure or infection and usually suggests immunity to the virus. It does not confirm a recent or active infection. To assess recent or acute infection, CMV IgM testing is also required.

This test is commonly done as part of TORCH panel screening during pregnancy to assess potential risk to the fetus. It is also used in organ transplant patients to monitor CMV status pre- and post-transplant.
