Thanks for the additional info, @TerryinCO. Can you give the reference ranges for the celiac antibody tests. The scores you posted are not of much value without reference range numbers since there are not industry standards for these tests as far as the the scales they use. What they are testing for is the same but how they concoct the tests is a little different from lab to lab. You will need to repost the original numbers as well as the reference ranges in a new post as you will not be able to edit the original post. Also, unfortunately, it doesn't seem your doctor ordered a "total IGA" test to determine of you are IGA deficient. If there is IGA deficiency, test scores for individual IGA celiac antibody tests will be artificially low. You mention that there are genetic tendencies on your mother's side for thyroid problems. Perhaps there is also an inherited tendency for celiac disease on that side as well. It's only in the last couple of decades has the medical community begun to understand that celiac disease has long fingers that extend far beyond gut symptoms.

Thanks for the replies, Trents and Knitty Kitty.   The endoscopy was a check on the Barret's esphagus status (every2-3 years).  So she wasn't really looking for Celiac conditions.  I was not on gluten free diet for the blood tests so no masking of results. The blood tests ordered afterward were (and results);  TTG (Anti-Tissue Transglutaminase) IgA Quantitative -  <4.0 (this is a 'weak positive' I beleive) ;  ENDOMYSIAL ANTIBODIES IGA  <1.10 ;  TISSUE TRANSGLUTAMINASE IGG AB <.82 ; and a CMP. I have been taking a B12 sublingual vitamin. I've been treated for hypothyroidism and GERDs for 20+ years.  Thyroid problems are genetic on my mother's side. With both your experience, I'd appreciate your input.  Thank you. Terry

Welcome to the forum, @TerryinCO, Have you been checked for nutritional deficiencies?  Damage to the intestines like your doctor found affects the absorption of essential nutrients.  Supplementing with B Complex, Vitamin D, and minerals like magnesium help ensure you are absorbing vitamins your body needs to heal.  Weight loss is often seen in the malnutrition that accompanies Celiac Disease.  Weight loss, Barret's esophagus, and hypothyroidism are related to Thiamine Vitamin B1 insufficiency.  Talk to your doctor and nutritionist about supplementing with Thiamine in the form Benfotiamine and other vitamins and minerals. Best wishes for your new journey with Celiac.  Keep us posted on your progress.

Pancreatic elastase is a digestive enzyme that requires Thiamine Vitamin B 1 to be produced.  Thiamine is needed to make insulin, too.  Thiamine, Niacin B 3, and Pyridoxine B6 are needed to make digestive enzymes and turn carbohydrates, fats and proteins into energy for the body, and for repair and healing of the body.  The Gluten free diet can be low in the eight essential B vitamins.  Gluten free processed foods are not enriched with vitamins and minerals like their gluten containing counterparts.  Supplementing with the water soluble B vitamins can ensure you're absorbing sufficient amounts of B vitamins to keep the body healthy.  Benfotiamine is a form of thiamin that helps heal the digestive tract.  Benfotiamine and Vitamin D help to reduce inflammation and calm immune responses, so if you are accidentally exposed, your autoimmune response might not be so bad. Supplementing with the B Complex vitamins is beneficial while healing.  Have you talked to a nutritionist?

Welcome to the forum, @TerryinCO! Do you know what blood tests were ordered? Was it for like you would have done for an annual physical (CBC/CMP) or celiac disease specific antibody tests? I find it interesting that your GI doc did the endoscopy and biopsy before he/she ordered blood tests to check for celiac disease, assuming the blood tests ordered were indeed specific for celiac disease. Normally, the sequence is the other way around. Was the GI doc doing the endoscopy for some other reason in the first place? The endoscopy/biopsy is considered the gold standard for celiac diagnosis so I also find it interesting that the doc reflexively felt a need to order blood work as well.  Just a heads up in case the bloodwork ordered was not specific for celiac antibodies: Going on a gluten-free diet before the blood draw for celiac antibody testing is done will likely invalidate the testing. You probably know this already but hypothyroidism (Hashimoto's disease) is common in the celiac population and there is a statistical correlation. And then there is the weight loss. And I assume you have suffered with GERD for a long time and that is what led to the Barret's. All symptoms of celiac disease.
