Total IGA

The Total Immunoglobulin A (IgA) test measures the concentration of IgA, a type of antibody that plays a crucial role in the immune system by protecting mucosal surfaces, such as those in the respiratory and gastrointestinal tracts. This test is used to assess immune system function and diagnose conditions related to IgA deficiencies or excesses.

Sample type:

Serum

Preparation:

You do not need to do anything special to prepare for the sample collection. Fasting is not required for this test.

Test type:

In person or via trained mobile phlebotomist

Biomarkers

IGA, Serum

Symptoms or conditions analyzed by this test

The Total IgA test evaluates the level of this antibody to assess immune function. Low levels of IgA can result in increased susceptibility to infections, especially of mucosal surfaces like the respiratory and gastrointestinal tracts. Elevated IgA levels may indicate chronic infections, autoimmune diseases, or certain malignancies. This test is essential for diagnosing immune deficiencies and monitoring related health conditions.
