IMMUNOGLOBULIN A

Overview

The Immunoglobulin A (IgA) test measures the level of IgA antibodies in the blood. IgA plays a critical role in the immune response, particularly in mucous membranes lining the respiratory and digestive tracts. Elevated or reduced levels may indicate conditions like immune deficiencies, liver disease, chronic infections, or autoimmune disorders. This test assists in diagnosing and monitoring such conditions.
