Negative Biopsy Positive Ttg

Hi - I had a weak positve tTG blood test (level was 28, 20-30 were weak positive). My mother has celiac. I have no GI symptoms but have had some muscle aches and joint pain for the past year. Anyway, the report after my biopsy said "The mucosa of the duodenum appeared atrophic." I know it needs to be looked at under a microscope, so I asked the doctor what that meant and he said that it appeared "pale looking" (or something like that, I was a little out of it). Anyway, the biopsy was negative. Has anyone else had a negative biopsy with a positive (or weak positive) tTG level? What does that mean? Thanks.

Cheers,

-Bill

Lots of people have had positive tTG with negative biopsy. It basically means you havent suffered enough damage to the villi that it showed up in the biopsy. It doesnt mean damage didnt occur...there likely is some damage but it could be easily missed considering the length of the intestines and the fact that they only take a few samples. It does NOT mean you dont have Celiac. With a positive tTG and a mother who is diagnosed Celiac...you can safely assume you have it and start the diet. :)

Thanks for the reply. I thought that might be the case, so I started the diet last week anyway, the day of the biopsy.

Bill,

I basically had the same experience. DR. noted 'mild flattening of the villi', told me to go gluten-free, and the biopsy report came back negative. After I went gluten-free i felt better.

One thing you could also do is look for a 2nd opinion on your biopsy. that's what i'm doing. i also did enterolab genetic testing, and found that i have 2 copies of the celiac gene, so that's confirmation for me to be strict about the diet.

Thanks again for the replies. Yes, this sounds like my experience. I'm going to stay on the diet for now, but I think I might pursue the second opinion or possibly additional testing (I've heard of enterolab but not sure what it involves). I'd like to be sure. I'm 44 and have never had any GI symptoms, so I wont be able to tell from going on the diet.

Cheers,

Mild flattening is still flattening. It is like being a little bit pregnant. Your doctor failed to realize that your celiac was caught at the beginning of the damage. This means less healing is needed, so you will be better in a shorter length of time on a gluten-free diet!

I was under the impression that the only way to see if the villi were flat was under a microscope. I'm not sure what to make of the subjective comments of the doctor performing the exam vs. the results of the biopsy. I'm going to discuss this with my GI specialist when he calls back ... I was a little out of it immediately after the procedure, so I didn't go into the details.

I thought so, too. I thought if they can actually SEE the damage, it must be pretty bad.

      Blood tests low iGA 4 years later digestive issues

      By trents · Posted

      Welcome to the forum, @Mmoc! Please include the reference ranges for the IGA and the TTG tests in your next post if you have access to them. We cannot comment much otherwise as different labs use different reference ranges for these tests and also different units of measurement. There are no universal standards as of yet so the raw test numbers are not always helpful. Having said that, if your IGA (what we usually call "total IGA") is low, the TTG-IGA score will be skewed and cannot be trusted. Other kinds of tests for celiac disease would need to be run, particularly those in the IGG family of tests. Perhaps this will be helpful:

      Blood tests low iGA 4 years later digestive issues

      By Mmoc · Posted

      Hi there any advice welcomed. I have had 4 years of symptoms ranging from immune related anaphylactic symptom sudden onset food allergy to peppers/paprika/chilli/capsicum family derivatives. all these allergies fizzled out and following a food challenge test in hospital I reintroduced them a few months ago. Since then my digestive system is a mess. i have since noticed that 4 years ago when testing for iga allergies my iga level was .62 and my ttg was less than .1 (due to symptoms I was probably eating very plainly at that time). should I insist on being retested for celiac? I’ve since read two indicators for celiac include: sensitive to spicy foods when in flare up tooth enamel weakness and symmetrical discolouration patches on teeth which I have had since childhood on my two front teeth     thanks

      Headaches / Migraines and Hypoglycaemia

      By trents · Posted

      This article does not address migraines at all.  Yes, red wine and sulfites are often mentioned in connection with migraine triggers. With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably. So, I think most of my migraines are tied to fluctuations vascular tension and blood flow to the brain. That's why the sumatriptan works so well. It is a vaso constrictor.

      Headaches / Migraines and Hypoglycaemia

      Excessive dietary tyrosine can cause problems.  Everything in moderation.   Sulfites can also trigger migraines. Sulfites are found in fermented, pickled and aged foods, like cheese.  Sulfites cause a high histamine release.  High histamine levels are found in migraine.  Following a low histamine diet like the low histamine Autoimmune Protocol diet, a Paleo diet, helps immensely.    Sulfites and other migraine trigger foods can cause changes in the gut microbiome.  These bad bacteria can increase the incidence of migraines, increasing histamine and inflammation leading to increased gut permeability (leaky gut), SIBO, and higher systemic inflammation.   A Ketogenic diet can reduce the incidence of migraine.  A Paleo diet like the AIP diet, that restricts carbohydrates (like from starchy vegetables) becomes a ketogenic diet.  This diet also changes the microbiome, eliminating the bad bacteria and SIBO that cause an increase in histamine, inflammation and migraine.  Fewer bad bacteria reduces inflammation, lowers migraine frequency, and improves leaky gut. Since I started following the low histamine ketogenic AIP paleo diet, I rarely get migraine.  Yes, I do eat carbs occasionally now, rice or potato, but still no migraines.  Feed your body right, feed your intestinal bacteria right, you'll feel better.  Good intestinal bacteria actually make your mental health better, too.  I had to decide to change my diet drastically in order to feel better all the time, not just to satisfy my taste buds.  I chose to eat so I would feel better all the time.  I do like dark chocolate (a migraine trigger), but now I can indulge occasionally without a migraine after.   Microbiota alterations are related to migraine food triggers and inflammatory markers in chronic migraine patients with medication overuse headache https://pmc.ncbi.nlm.nih.gov/articles/PMC11546420/

      Then we would need to cut out all meat and fish as they are richer sources of tyrosine than nuts and cheese. Something else about certain tyrosine rich foods must be the actual culprit.
