The Cytomegalovirus (CMV) Antibodies IgG blood tests aids in diagnosis of CMV infection. In general, a fourfold increase in IgG titer over a four-week period is presumptive evidence of recent infection; however, this relationship may not hold true in certain individuals due to biological fluctuation of the antibody levels. The best test to diagnose acute CMV infection is the CMV IgM assay test [096727].

CMV causes an infectious mononucleosis syndrome clinically indistinguishable from heterophil positive mononucleosis, a very common entity. Significant CMV titers are found almost universally in patients with AIDS, and CMV genome has been demonstrated in the cells of Kaposi sarcoma. CMV is a significant cause of postcardiotomy, post-transplant, and postpump hepatitis syndromes.
