Does it make sense for me to request the endoscopy be redone?

Doctor did my endoscopy, biopsies, and celiac disease panel without telling me to eat gluten before.

Obviously all came back negative because I was GF for 2 months. Started eating gluten and my allergy/immunology doc is going to do another blood panel. He's also a GI so I might switch docs considering how negligent my doc has been.

Also have SIBO and probably something else as I've been sick for a year. I read about leaky gut being caused by trauma and hence can lead to gluten sensitivity and in some cases CD. It's also possible I've had CD due to my life long bowel issues.
