IMMUNOGLOBULIN M

Overview

The IgM (Immunoglobulin M) serum test measures the level of IgM antibodies in the blood, which are among the first antibodies produced by the immune system in response to an infection. High IgM levels indicate an active or recent infection, while lower levels may suggest past exposure or immunity. This test is commonly used to diagnose infections and assess immune response, helping to identify early-stage infections.
