The reason why shellfish allergy is asked is because of the link between shellfish allergy and iodine allergy (shellfish are rich in iodine). That does not mean that if your allergic to shellfish then you are allergic to iodine - you may be allergic to another component that is in the shellfish. Iodine is used in the thyroid scan as a dye and is injected into your veins. If you are allergic then the reaction would be quite quick and potentially serious. Asking about a shellfish allergy is to try to risk stratify those that may be more susceptible for a reaction and "prepare" the technician / radiologist for the worse case scenario. The main allergic reaction we would be worried about would be true anaphylaxis (if you've not heard of this then you probably not had it). Rashes and facial swelling would indicate a allergic reaction. Sickness, diarrhea and feeling "off" would suggest an intolerance rather than a true allergic reaction. Happy New Year! El Tango
