If you had a positive biopsy there is a good chance you have celiac. Have you had the blood tests redone or did you get a copy of them? Some doctors will call a low positive negative. You might want to get bloodwork redone and then give the diet a good strict try no matter what the results. Or you could just go gluten free. Since both blood and biopsy have high rates of false negatives but not false positives the positive biopsy was significant in spite of the negative blood tests. Many doctors would have diagnosed with the positive biopsy since that has been considered the 'gold standard' for diagnosis.

False positive biopsies are possible, but they would could involve some other fairly serious issue, and you ought to know if that was the case.

The more common cause of false positive is lab mistake; apparently it's really easy to flip the sample the wrong direction and hide the villi (Open Original Shared Link). Maybe that's what the doctor thinks happened? Or maybe your positive was only for minor changes that can be explained by several different conditions?

I'd be asking your doctor to explain why he thought you were negative despite the biopsy. There should probably be some answer other than "Oh... Well, the blood work wasn't positive."

I got retested for Celiac on friday, my gastro doc told me that he would call me with the results of the test. I am having so many problems right now and have lost 21 pounds in 1 month and continue to lose weight, i have mouth ulcers and alternating diarrhea and constipation. i am very worried that i am going to lose more weight and my gastro will tell me that the blood tests were negative. then what will i do? maybe just go gluten free once and for all.

Oh, wow. I hope the blood tests clear things up for you. Between your symptoms and the positive biopsy you had before, it sure sounds like celiac.

Wow...that's a huge weight loss, hun! :o When you say you were retested on friday, do you mean blood tests? Hopefully you will get some answers, but even if they are negative, you should still give the gluten free diet a good try (2-3 months). Sometimes gluten intolerance doesn't show up in your blood work, but it still wreaks havoc on your body. :(

Definately go gluten free, no matter what the test says.

yes they drew blood tests again on friday for Celiac panel because of the problems i am having with severe weight loss. i do not know why i am losing all this weight, i am eating but sometimes i dont have any interest in food and have alternating bouts of diarrhea and constipation. if i go gluten free right now and then they want to do a upper endoscopy would the results still show if i was gluten free? i dont know how long it takes to get the Celiac blood tests back.

If you are going to have an endo do keep eating gluten until that is done. Even on gluten there is still a chance of false negatives with testing so when all testing is done give the diet a good strict try.

      Unusual bright yellow but odourless discharge

      Yes, I, too, have osteoporosis from years of malabsorption, too.  Thiamine and magnesium are what keep the calcium in place in the bones.  If one is low in magnesium, boron, selenium, zinc, copper, and other trace minerals, ones bone heath can suffer.  We need more than just calcium and Vitamin D for strong bones.  Riboflavin B 2, Folate B 9 and Pyridoxine B 6 also contribute to bone formation and strength.   Have you had your thyroid checked?  The thyroid is important to bone health as well.  The thyroid uses lots of thiamine, so a poorly functioning thyroid will affect bone heath.

      That sounds so very likely in my case! I will absolutely ask my doctor on my next bone check coming up in March... Thanks a lot!

      Calcium levels as measured in the blood can be quite deceiving as the body will rob calcium from the bones to meet demands for it by other bodily functions. Also, supplementing with calcium can be counterproductive as it tends to raise gut pH and decrease absorption. More often than not, the problem is poor absorption to begin with rather than deficiency of intake amounts in the diet. Calcium needs an acidic environment to be absorbed. This is why so many people on PPIs develop osteoporosis. The PPIs raise gut pH. And some people have high gut PH for other reasons. Low pH equates to a more acidic environment whereas high pH equates to a more basic (less acidic) environment.

      Kind thanks for all this valuable information! Since my Folate was/is low and also my Calcium, there IS a chance I am low in B vitamins... My doctor only measured the first two, oh and Zinc as I has twisted her arm and guess what, that was mega low too. So who knows, until I get myself tested properly, what else I am deficient in... I did a hair mineral test recently and it said to avoid All sources of Calcium. But this is confusing for me as my Ca is so low and I have osteoporosis because of this. It is my Adjusted Ca that is on the higher side and shouldn't be. So am not sure why the mineral test showed high Ca (well, it was medium in the test but relative to my lowish Magnesium, also via hair sample, it was high I was told). But anyway, thanks again for the VitB download, I will look into this most certainly!

      Allergy medication: cetirizine by the HealthA2Z is it gluten free?

      By ElisaAllergiesgluten · Posted

      Hello good afternoon, I was wondering if anyone has ever brought their anti-allergy pills? I have been wanting to use their Cetirizine HCI 10mg. They are called HealthA2Z and distributed by Allegiant Health.I’m also Asthmatic and these allergies are terrible for me but I also want to be sure they don’t have any sort of gluten compound.    I have tried calling them but to no avail. Has anyone ever used them? If so, did you had any problems or no problems at all?    thank you
