Food Allergy IgE




IgE is the antibody most widely known for its involvement in allergies of all kinds. It may also be involved in protection of the body from parasites. Elevated IgE in blood is associated with a history of excessive allergies.

Allergies are defined as specific reactions within the immune system involving an antibody called immunoglobulin E (IgE). Immediate responses such as hives, congestion or swelling typically result from IgE activity. Traditional scratch testing identifies IgE triggers such as pollen or peanuts, which can cause symptoms that range from annoying to lethal.
