The Immunoglobulin A (IgA) test is a laboratory analysis that measures the concentration of IgA, a type of antibody, in a patient\'s blood. IgA is one of the major classes of antibodies present in the human immune system and is primarily found in mucous membranes, such as those in the respiratory and gastrointestinal tracts.The IgA test is used for various purposes:Assessment of Immune Function: Measuring IgA levels helps assess the overall functioning of the immune system. Low levels of IgA can indicate immunodeficiency, making the individual more susceptible to infections.Diagnosis of Immunodeficiency Disorders: Selective IgA deficiency is a common primary immunodeficiency disorder. This test can help diagnose such conditions and guide treatment.Gastrointestinal Disorders: Elevated IgA levels in the gastrointestinal tract are associated with conditions like celiac disease and inflammatory bowel disease (IBD). Measuring IgA in the stool can be useful in diagnosing these disorders.Allergy Testing: IgA antibodies play a role in allergic reactions. Elevated IgA levels may be observed in individuals with certain allergies.Scheduling the Immunoglobulin A (IgA) test through our online platform offers a convenient way to access this important diagnostic tool. It assists healthcare professionals in evaluating immune function, diagnosing immunodeficiency disorders, and identifying conditions related to mucous membrane immunity, ultimately leading to accurate diagnoses and appropriate treatment plans.
