Update on the diagnosis and treatment of shellfish allergy

Shellfish allergy is a frequent, long-lasting, lifethreatening disorder. As shellfish consumption increases, the number of allergic reactions to shellfish is expected to continue to rise as well. During the past decade, much has been learned about the allergens involved in shellfish allergy. Potential cross-reacting allergens between shellfish and other arthropods have been identified. As our knowledge of shellfish allergen improves, we will be able to develop more accurate methods of diagnosing shellfish allergy. In addition, extensive research is currently under way for the development of safer, more effective methods of managing shellfish hypersensitivity.
