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.
Preparation
No fasting or special preparation is needed. Tell your doctor about any medications or recent illnesses, as they can affect results.
Results and what they mean
Results are reported as a number with a reference range, typically in milligrams per deciliter (mg/dL). Your clinician interprets the value along with your symptoms and other tests. This is general information, not medical advice; discuss your results with a healthcare professional.
