I just posted about this! I feel like I had a false positive as well. I had positive results a year ago, but didnt get better with the diet. my endoscopy was also negative. i JUST started eating wheat again and want to get re-tested to see what happens this week. After a year of being gluten free, it's been tough... I'm glad you posted-- now I know which blood test I REALLY need. I also had the ones that were not very conclusive. Thanks for your post!
