DESCRIPTION: The CMV IgM Enzyme Immunoassay is a diagnostic test designed to detect IgM antibodies specific to cytomegalovirus (CMV) in serum or plasma. The presence of IgM antibodies typically indicates recent or acute infection with CMV, making this test valuable for diagnosing active infections. This assay provides crucial insights into the individual’s immune response. Clinicians use this test to identify recent CMV infections, particularly in pregnant women and immunocompromised patients, where timely diagnosis is essential for preventing complications.
