DESCRIPTION: The Rubella IgM Enzyme Immunoassay is a diagnostic test designed to detect IgM antibodies specific to the rubella virus in serum or plasma. IgM antibodies are typically produced during the early stages of infection, making this test valuable for identifying acute rubella infections. The assay provides crucial insights into the individual’s current immune response. Clinicians use this test to diagnose recent infections, particularly in pregnant women, to prevent complications associated with congenital rubella syndrome.
