Diagnosis typically involves a combination of medical history, physical examination, and specific tests such as:
Skin Prick Test: A tiny amount of soy protein is placed on the skin, which is then pricked to see if a reaction occurs. Blood Test: Measures the level of immunoglobulin E (IgE) antibodies to soy proteins in the blood. Oral Food Challenge: Conducted under medical supervision, small amounts of soy are ingested to monitor for a reaction.
