New blood test may take the guesswork out of shrimp allergy diagnosis in kids

This study will check if measuring IgE antibodies to two shrimp proteins (tropomyosin and hemocyanin) in the blood can accurately diagnose shrimp allergy in children. About 129 kids with suspected shrimp allergy will take part. They will have a food challenge, skin test, and blood draw. The goal is to see if these blood tests can replace or reduce the need for risky food challenges.
