This test measures IgM antibodies, the first line of defense produced by the immune system in response to infection.
Diagnostic Value: Elevated IgM levels suggest recent infection or immune activation, while low levels may indicate immune deficiency or chronic illness.
Clinical Significance: Measuring IgM assists in evaluating immune readiness and identifying acute versus chronic allergic or infectious conditions.
Symptom Correlation: Patients may present with fever, congestion, or inflammation linked to early immune response.
Because it represents the body’s immediate antibody response, Total IgM testing complements IgG and IgA assessments in immune system profiling.
