Dr. Gary Steven answered

Specializes in Pediatric Allergy and Asthma

Not unusual: Most people who develop a shellfish allergy are allergic to one or types. However, if you have an allergic reaction to one type of shellfish, it's a good idea to see an allergist for skin testing to the other types of shellfish before you go out to try them.
