What is the purpose of this test?
Order this IgE Antibody (Anti-IgE-IgG) Blood Test to detect IgG antibodies specific for IgE in the blood to screen for autoimmune urticaria. Chronic urticaria is a skin disorder that affects 1 to 6% of people. It is characterized by itchy red welts that come and go. Autoimmune urticaria occurs when the body produces autoantibodies that mistakenly target mast cells, causing hives. This condition can be diagnosed through an anti-IgE test, which measures the presence of these autoantibodies. This test can help doctors determine the cause of a patient's hives and rule out an autoimmune disorder if the results are negative. Finding the proper treatment for hives can be challenging, especially when the cause is unknown.
