The Immunoglobulin A (IgA) test is a blood test that measures the levels of IgA antibodies in the blood. IgA is a type of antibody that plays a crucial role in the immune system's defense against infections.
The IgA test is used to diagnose conditions related to IgA deficiency or IgA-related disorders. It can help in assessing immune function and detecting autoimmune diseases, allergies, and certain infections.
Low levels of IgA in the blood may indicate IgA deficiency, which can lead to an increased risk of infections, especially in the respiratory and gastrointestinal tracts. On the other hand, elevated levels of IgA may be associated with autoimmune disorders, chronic infections, or certain cancers.
The IgA test is often part of a panel of tests used to evaluate the immune system and can provide valuable information for diagnosing and managing various health conditions. Interpretation of IgA test results should be done in consultation with a healthcare provider.
