Quick answer
The IgA Lab Test is a blood test that measures immunoglobulin A, the antibody class that protects mucosal surfaces such as the airways, gut, and mouth. IgA levels can be low, normal, or high, and each pattern points to different possibilities. The test is often part of an immune evaluation, and it is also used before certain antibody tests because IgA deficiency can affect how those results are interpreted.
What this test measures
Immunoglobulin A is one of the major antibody classes. It is found in secretions and on mucosal surfaces, where it helps block germs from attaching. Serum IgA reflects the amount circulating in the blood, which is related to but not identical to the IgA present in secretions.
The test requires a blood sample and reports a concentration, usually in milligrams per deciliter. Results are compared with age-adjusted reference ranges. Low IgA can be a sign of selective IgA deficiency, a relatively common immune finding, while high IgA can occur with liver disease, chronic infections, and some inflammatory conditions.
Providers may order an IgA level when a person has recurrent infections, chronic digestive symptoms, or an immune condition, and when celiac or other antibody tests that rely on IgA are planned. A qualified healthcare provider should interpret the level with the person's history and any additional immunoglobulin results.
