Question: If someone is allergic to shellfish is it the iodine in it or is it something different?
Answers:
There are unsubstantiated concerns of a cross reactivity between shellfish allergy and iodine/contrast allergy -- some old medical forms still list this incorrectly as a contraindication. If you are allergic to shellfish, you do not need to avoid iodine or radiocontrast material. It is possible to be allergic to iodine or radiocontrast material, but those allergies are not related to shellfish allergies, so you do not need to worry about cross-reactions.
