CMV immunoglobulin G testing is recommended only in patients who are at lower risk for CMV to detect latent CMV infection. CMV immunoglobulin G testing is not necessary in patients at higher risk for CMV, including men who have sex with men and injection drug users, because they can be assumed to be CMV positive. Testing for CMV antibody in low-risk populations is recommended to foster patient counseling in avoidance of CMV infection through practicing safe sex and to avoid transfusion except with CMV-negative blood products. Patients at lower risk for CMV infection, e.g., patients who are heterosexual and have not injected drugs, should be tested for latent CMV infection with an anti–CMV immunoglobulin G upon initiation of care.
