Reverse Testing?

[Mattie-Jack]

Does this make any sense to anyone?

My child tested positive for Celiac via blood work, however, had a negative biopsy. Doctors have concurred that a Celiac diagnosis can not be obtained. I have put her on a gluten-free diet. If she had her labs redone after 3-6 months on a gluten-free diet, would the results be negative for Celiac, therefore, diagnosing by diet elimination? Sort of a reverse diagnosis?

Many doctors will give a celiac diagnosis based on positive blood testing and a positive response to the diet.

Yes if after being strictly on the diet the blood antibodies go down you have your answer. False negatives with both blood and biopsy are not uncommon especially with children. Since your child had a positive blood test you should put him strictly on the diet. Some doctors will diagnosed based on his response. It would be a good idea to get the testing done on all family members.
