Anti-IgE IgG Blood Test

Autoimmune Urticaria, Hives


Test Code: 18877
Specimen Type: Blood

Description:

Anti-IgE IgG Blood Test

This test looks for IgG antibodies to immunoglobulin E (IgE) or IgE receptors.  Anti-IgE antibodies are typically associated with autoimmune Urticaria.   Urticaria, more commonly known as hives, are red itchy welts that appear on various parts of the skin.  Hives can be triggered by a number of disorders including as part of an allergic response.  Normally, hives appear and fade in a short period of time.  Chronic Autoimmune Urticaria is a condition in which people break out in hives than can persist for six weeks or longer for no apparent reason.  Autoantibodies produced by the immune system mistakenly target mast cells that are responsible for histamine production.  This causes the body to react as though it has encountered an allergen which causes the development of hives.  Identifying the proper way to treat hives can be difficult because oftentimes, the cause is unknown.  Anti-IgE testing can help a person's doctor to make a diagnosis when their hives are being caused by an autoimmune disorder.  Negative results can also help to rule out an autoimmune disorder as the cause.

This test is typically ordered when a person has chronic hives with no apparent cause, especially if they are not accompanied by other common allergy symptoms. 

Turnaround for this test is typically 3-12 business days.
