This study will evaluate whether blood tests that measure IgE antibodies to two shrimp proteins, tropomyosin and hemocyanin, can help diagnose shrimp allergy in children. Children with suspected IgE-mediated shrimp allergy will undergo oral food challenge, skin prick testing, and blood sampling. Oral food challenge results will be used as the reference standard to determine whether these tests can accurately identify true shrimp allergy and help improve diagnosis in clinical practice.
