Contrast dye allergy
If someone is allergic to fish/shell fish, is a contrast dye procedure feasible? Thank you
The cross reactivity between the contrast material used to day for radiographic procedures does not cross react with shellfish. This is a misnomer that has been perpetuated for years.
Studies have shown that this is not a significant risk for a reaction. However, many physicians may elect to prophylactically treat with antihistamines and/or corticosteroids to protect against medical legal issues since the belief that contrast material and shellfish is imprinted in the general publics mind.
