How is a sublingual provocative challenge used to diagnose food allergies?

ANSWER

Another controversial approach is called sublingual or, if it is injected under the skin, subcutaneous provocative challenge. During this procedure, you'll be given diluted food allergen is under your tongue. This procedure applies if you feel that your arthritis, for instance, is caused by food allergies. The technician will then ask you if the food allergen has aggravated your arthritis symptoms. In clinical studies, researchers have not shown that this procedure can effectively diagnose food allergies.
