The Cytomegalovirus (CMV) Antibodies IgG blood tests aids in diagnosis of CMV infection.

The best test to diagnose acute CMV infection is the CMV IgM assay test .
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.
