Celiac Test Gluten Protocols
The gluten free diet protocols depend which celiac test you're getting:
For the "Monitoring" test (for those already diagnosed with celiac), you do not need to be eating gluten for that test. It measures the effectiveness of your gluten-free diet.
For the "Screening test" (to test your likelihood of having celiac), you do need to follow the gluten protocols. If you’re currently 100% gluten-free then you need to eat 2 crackers or equivalent for 8 weeks.
