Drinking Glucose To Test For Sibo? in Food Intolerance & Leaky Gut Posted August 30, 2015 · Report to Admin I was recently glutened and my doctor suspected SIBO, but my celiac blood test revealed elevated antibodies. What a relief! I'm not exactly sure why that's a relief as I also had elevated antibodies but still have symptoms months after being gluten free. I bet it's possible to have both gluten sensitivity/celiac and SIBO.. having one doesn't rule out the other. There are a lot of unlucky people out there.. haha And even if your home test is positive - your doctor won't take your word for it! He will want to do his own test. True.. I didn't realize this was something I could have done through the GI doctor. I just panicked one day and did a good search, found this, it was only 125 bucks so I bought it. Doesn't hurt I guess to test a few times. I'm not sure why you are concerned about the glucose? It is a simple sugar, not related to the gluten protein. You're right.. I don't know why I didn't trust the glucose that came with the kit. I went ahead and ordered non GMO glucose off amazon and will use that for my test. I'll post back on this thread with my results!
