Question

Quizplus · Accepted Answer

The double-blind, placebo-controlled food challenge is considered the most accurate and reliable test for diagnosing food allergies. It involves giving a patient a small amount of the suspected allergen, in a disguised form, along with a placebo, and then monitoring the patient for any signs of an allergic reaction. This is repeated multiple times with different doses and combinations of allergen and placebo to determine if the reaction is indeed caused by the food allergen. Other tests such as skin prick tests and identification of specific IgE can provide helpful information but are not considered as definitive as the food challenge. Saliva testing and small bowel biopsies are not typically used in the diagnosis of food allergies.
