What is a sublingual provocative challenge to help diagnose food allergies?

ANSWER

It's a method that some people use to diagnose food allergies -- but research hasn't shown that it's effective at that. During this procedure, you'll get a diluted food allergen placed under your tongue to see if it has an effect. For instance, if you feel that your arthritis is caused by food allergies, the technician will ask you if the food allergen used in the test worsened your arthritis symptoms.
