Unrelated: There is a common misunderstanding that one can be allergic to iodine yet this is incompatible with life -our thyroid hormone production depends on it. You are allergic to the muscle protein in shellfish and not to the iodine. The contrast dye reaction is from the molecular structure of the dye which releases histamine. You are not at higher risk for a dye reaction because of a shellfish allergy
