What does a differential diagnosis mean for food allergies?

ANSWER

A differential diagnosis means distinguishing a food allergy from food intolerance or other illnesses. If a patient goes to the doctor's office and says, "I think I have a food allergy," the doctor has to consider the list of other possibilities that may lead to symptoms that could be confused with a food allergy.
