In patients with shellfish allergy, the use of intravenous contrast is associated with which correlation?

• A. Increased risk
• B. Absolute contraindication
• C. No correlation
• D. Shellfish allergy is a contraindication to IV contrast

Answer: (C)

Shellfish allergy does not predict how a person will react to iodinated intravenous contrast. Shellfish allergy is an immune response to shellfish proteins, while iodinated contrast agents are chemical compounds used to enhance imaging and are not related to shellfish allergens. Therefore, there is no correlation between a shellfish allergy and adverse reactions to IV contrast, so it is not a contraindication. The real considerations with IV contrast involve prior contrast reactions, asthma or atopy, and kidney function, which guide precautions or premedication if needed.
