Will I need food allergy testing to diagnose a shellfish allergy?

After asking you about your symptom history, your provider may do food allergy testing to confirm a diagnosis:

• Skin prick test: During this in-office test, your provider places a drop of the allergen on your skin and pricks your skin. The drop seeps into your skin. Your provider will confirm a diagnosis if a red, itchy bump appears after 15 to 30 minutes.
• Blood test: A blood test can help detect whether you have a specific food allergy.

These tests are not conclusive. Together with your symptoms and history, your provider will make a diagnosis.
