Diagnosing the true cause of someone's "gluten allergy" would allow them to start eating gluten again. Since gluten is pretty much everywhere, I'd say that'd be a nice quality of life improvement.
Or the diagnosis might confirm the patient's suspicions, and they might have to monitor their gluten intake for the rest of their life. Either way, there should be actual evidence available before a definite conclusion is reached.
Low-cost screenings, such as 23&Me mail-in swab tests, elimination diets, or common blood and urine tests are a great way to start building up that objective evidence without first doing harm to your patient's wallet.
The FDA just wants to make sure that 23&Me's tests are accurate, which could actually lead doctors to trust them more rather than replicating them at the patient's expense.
