Better be safe: if you are sure of a certain food causing symptoms, and if the symptoms are severe enough, you just need to avoid such food , you don't even need a confirmatory allergy test, let alone a challenge test, listen to your allergist, avoid the trigger, keep epinephrine injection and antihistaminic handy, good luck

Try blood test: Although blood test (ImmunoCap IgE) for food allergy may not be as sensitive to skin test, the results are more specific. In your case, I think blood tests should be obtained first and skin test to follow if blood test turns out to be negative. In double-blind food challenges, many presumed food allergies turned out to be false. Avoiding too many foods may lead to nutritional deficiency.
