The Cytomegalovirus (CMV) IgM Antibody Test detects IgM antibodies, indicating a recent or active CMV infection. This blood test helps diagnose primary CMV, reactivation, or reinfection, especially important for pregnant women, transplant candidates, and immunocompromised patients. Used with CMV IgG testing, it helps distinguish new infections from past exposure for accurate clinical evaluation.

The Cytomegalovirus (CMV) IgG Antibody Test detects IgG antibodies to CMV, indicating past infection or immunity. This blood test helps determine prior exposure, assess immune status in pregnancy, transplant patients, or immunocompromised individuals, and guide risk evaluation. A positive result shows past CMV infection, while results are used with IgM testing to distinguish recent vs. past infection.

The Cytomegalovirus (CMV) IgG IgM Antibodies Test detects both recent and past infection with CMV, a common herpesvirus. IgM indicates recent or active infection, while IgG shows past exposure and possible immunity. Doctors order this test for pregnant women, immunocompromised patients, or those with unexplained fever or fatigue. Results help diagnose CMV, guide treatment, and assess risk of complications such as congenital infection or organ damage.

The Cytomegalovirus IgG Avidity Test measures the binding strength of CMV IgG antibodies to help distinguish recent infection from past exposure. Low-avidity antibodies typically indicate a primary or recent CMV infection, while high-avidity antibodies suggest past infection or long-term immunity. This test is especially important in pregnancy, where identifying recent CMV infection can help assess risk of congenital transmission.

The Absolute Lymphocyte Count Test quantifies lymphocytes in blood, expressing immunity status through an absolute cell count rather than relative percentage. It aids in diagnosing immune disorders, tracking viral infection recovery, or identifying early signs of hematologic disease. By distinguishing lymphocytosis and lymphopenia, this test provides clinicians insight into immune suppression, overactivation, or recovery phases in infections or immunocompromised states.
