Immunoglobulin A Blood Tests

The test measures the level of Immunoglobulin A (IgA) in the blood. IgA is an antibody that plays a crucial role in the immune system's defense against infections.

Elevated levels of IgA may indicate certain health conditions such as chronic infections, autoimmune disorders (e.g., rheumatoid arthritis, lupus), liver diseases, and certain types of cancers. It can also be associated with gastrointestinal disorders like celiac disease and inflammatory bowel disease.

IgA deficiency is a condition where the body produces insufficient amounts of IgA, making individuals more susceptible to infections, particularly in the respiratory and gastrointestinal tracts.
