Legume allergies are among the most common food-related allergies and includes peanuts, which are one of the most allergenic foods. In the case of legume allergies, the body sees certain proteins in the legume as a toxin, rather than a food. Allergic reactions can be caused by ingestion, skin contact, and even inhalation. Peanut allergies typically develop during childhood and are usually lifelong. In most cases, allergy to peanuts signifies allergy to many other types of legumes. Peanut allergies have been known to cause some of the most severe allergic reactions of all food allergies, including anaphylaxis and even death. Skin prick tests are usually performed on the lower forearm, but can be performed on any site of the body. Sometimes when there are many allergens that need to be tested it is performed on the back. One of the substances is normal saline, which acts as a negative control (it should always be negative), and one of the substances is histamine, which acts as a positive control (it should always be positive). Drops of the allergens are placed on the skin, as well as histamine and saline, which are then pricked with a clean lancet. This will feel like a mozzie bite or you may not feel the skin pricks at all. Results are read at 15 minutes by measuring the weal and flare response, or a mosquito-like lump which can occur if you are allergic to that substance. You may experience itching at sites where you react to the allergen. After the test you can put something like calamine lotion on to stop the itching, or take an antihistamine if you react particularly significantly. As the results are available within 15-20 minutes, you can discuss the results with your doctor at the time of the test.
