Cytomegalovirus (CMV) IgG
Cytomegalovirus (CMV) IgG
Cytomegalovirus (CMV) IgG test detects the presence of IgG antibodies that develop against cytomegalovirus infection. CMV infection is a common viral infection that causes mild, flu-like symptoms in normal individuals. In immunocompromised (weak immune system) individuals such as HIV or cancer patients, CMV is dangerous. Infants who are exposed to cytomegalovirus before birth, may experience eyesight problems, deafness, seizures, cerebral difficulties, and other serious illness. This test helps in the early detection and diagnosis of cytomegalovirus infection and prevents its related complications.
