Fragen und Antworten zu IgA
What is the respective laboratory value?
IgA is an antibody that plays an important role in the immune system, especially in the mucous membranes of the gastrointestinal tract, the respiratory tract, and the urogenital tract. The laboratory value measures the concentration of IgA in the blood and is used to assess the immune status and chronic infections.
For whom is such a test to be considered?
An IgA test is recommended for: • People with recurrent infections, especially of the mucous membranes • Patients with suspected autoimmune diseases such as celiac disease or IgA nephropathy • Diagnosis and monitoring of chronic infections • Patients with suspected immunodeficiencies or excessive antibody production
What is it used for?
The test serves the diagnosis of immunodeficiencies, chronic infections and autoimmune diseases. It is also used to evaluate the function of the immune system.
What can be inferred from that?
An elevated IgA level indicates: • Chronic infections (e.g. respiratory diseases) • Autoimmune diseases such as celiac disease or IgA nephropathy • Liver diseases such as cirrhosis A low value indicates an IgA deficiency, which is associated with an increased risk of infections. Symptoms of abnormal IgA levels can include: • Frequent infections of the respiratory or gastrointestinal tract • Unexplained inflammation or autoimmune reactions
What is the ideal time for a test?
The testing can be carried out at any time of the day and is independent of food intake.
Particularly interesting?
• An IgA deficiency is one of the most common immunodeficiencies and often remains asymptomatic, but can increase the risk of infections. • If celiac disease is suspected, in addition to IgA, a specific antibody test (tTGIgA) should be performed. • Chronically elevated IgA levels can indicate IgA nephropathy, a common cause of kidney damage.
