Diagnosing Sesame Allergy
Blood tests measuring specific antibodies can effectively identify sesame allergies. These tests detect immune system responses to sesame proteins, providing crucial information for diagnosis and treatment planning. Early identification is particularly important given that sesame allergic reactions can be severe and unpredictable.
Other Relevant Tests
