Could I be allergic to X-ray dye?


Some procedures for diagnosis and treatment of cardiovascular disease use contrast dye. Angiograms are one example. These diagnostic tests rely on a special type of X-ray dye to help your physician gather images of your blood vessels and identify any life-threatening blockages.

It is possible to be allergic to the contrast dye. If you have a known allergy to shellfish, iodine or X-ray dye, you should let your physician know.

The chance of a life-threatening reaction to the dye is very small.
