Diagnosis usually involves a combination of medical history, physical examination, and specific tests such as:
Skin Prick Test (SPT): A small amount of peanut protein is placed on the skin, which is then pricked with a needle. If a raised bump appears, it indicates an allergic reaction. Blood Test: Measures the level of specific antibodies (IgE) to peanuts in the blood. Oral Food Challenge: Conducted under medical supervision, the child is given small, increasing amounts of peanut to see if they have an allergic reaction.
