Yes, many here. I guess your blood test is only as good as your lab tech. And false negatives do happen. An endoscopy would tend to be more accurate.

There's a lot of factors here. It's possible to have a negative blood test, but know that it could be a false negative. There is a percentage of people that cannot make type "A" antibodies. A celiac panel should always include a "Total serum" check to determine if this is the case for you. Also lab mistakes can happen and old test kits or kits that have been improperly stored can fail. In strongly suspected cases a negative blood test might be rechecked at another lab.

All that said, I think every bit of research clearly shows that the endoscopy is much less effective than the blood test. The endoscopy has frequent false negatives, because early damage can be hard to pin down, and because damage may be spotty and can be missed with sampling. False positives occur when a tech miss-orients a sample or confuses damage from another digestive condition for celiac related damage.

      High Deamidated Gliadin Abs, IgA after being gluten-free for 6 months

      By RMJ · Posted

      It can take longer than 6 months for antibodies to drop to the normal range,  My DGP IgA took a few years as I got stricter and stricter about being gluten free  But having symptoms again could also mean you’re getting some gluten in your diet.

      High Deamidated Gliadin Abs, IgA after being gluten-free for 6 months

      By TexasCeliacNewbie · Posted

      Hi, I just had my 6 month check after being diagnosed Celiac 6 months ago.  All of my panel numbers were normal except: Deamidated Gliadin Abs, IgA (It is 31 with high being over 30)  I have also been having symptoms again. Am I not actually being as careful as I think I am or does it take longer than 6 months for this particular test to come back down?  I can't get ahold of my doctor this week as she is out.     Thank you!

      Diagnosis and further testing Celiac

      That is very strange, because it looks to me like two very different test results, but for the same test! It's definitely time to contact your doctor for clarity on this.

      Scott, thank you SO MUCH for this!! She has been through so much in the last three years as we've tried to track down answers. This language will definitely help me help her to reframe.
