The IgA lab test measures the amount of immunoglobulin A (IgA), an antibody that helps protect mucous membranes in the respiratory and digestive tracts. It is ordered to evaluate immune function, screen for IgA deficiency, or monitor conditions like celiac disease and chronic infections.
What it measures
- Total IgA — Overall level of IgA antibody in the blood.
- IgA subclass 1 — One of two subtypes; helps pinpoint specific deficiencies.
- IgA subclass 2 — The other subtype; often checked if total IgA is low.
Who it is for
A doctor may order this test if you have frequent infections, digestive problems, or symptoms suggesting an immune disorder. It is also used before certain celiac disease tests that rely on IgA.
