An allergic reaction is a serious condition that many Americans face due to an abnormal immune response in the body, which can be fatal in some cases.
Allergic reactions occur when the immune system responds to foreign allergens that are not generally considered harmful. Mild reactions may indicate mild symptoms such as inflammation and, in more severe cases, may cause anaphylactic shock. Allergies to certain foods, such as peanuts, are a common allergic reaction that affects a small part of the population.

Type III antibodies begin to appear hours after responding to the allergen and are often associated with lupus, serum sickness, and Arthus reactions.
