Endoscopy dates

[normagain]

My blood test showed probable celiac last Saturday and I started gluten free diet immediately that day. The good people of this community advised to stay on gluten foods til endoscopy scheduled for May 31. Could not do it earlier in May as I am leaving town for the month. So I was thinking of getting on cancellation list if opening pops up over next couple weeks. So I was on full gluten before blood test Saturday then started gluten free til yesterday, 4 days, started gluten again yesterday. When will I have enough gluten in system to have endoscopy giving true result? Hope this was clear.

It may be better to just keep your original appointment, and the start eating lots of gluten 2-3 weeks before your endoscopy. 

Here is more info about how to do a gluten challenge for a celiac disease blood panel, or for an endoscopy:

"...in order to properly diagnose celiac disease based on serology and duodenal histology, doctors need patients to be on gluten-containing diets, even if they are causing symptoms, and this is called a "gluten challenge."

• Eat gluten prior to celiac disease blood tests: The amount and length of time can vary, but is somewhere between 2 slices of wheat bread daily for 6-8 weeks and 1/2 slice of wheat bread or 1 wheat cracker for 12 weeks 12 weeks;
• Eat gluten prior to the endoscopic biopsy procedure: 2 slices of wheat bread daily for at least 2 weeks;

and this recent study recommends 4-6 slices of wheat bread per day:
