Blood Test Results

Hi all,

I was diagnosed with IBS 4 years ago following a stomach virus. Celiac blood testing/endoscopy and colonoscopy all negative back then. Over the years my symptoms havn't improved so I went to a new specialist who started from the beginings.

New blood test results are;

Deamidated Glaidin IgA - 34 u/ml (normal <15)
Deamidated Glaidin IgG - 71 u/ml (normal <15)
Tissue Transglutamunase IgA - 98 u/ml (normal <15)
Tissue Transglutamunase IgG - <1 (normal <15)

I am going in for a biopsy in a few weeks.

Can anyone tell me if these results are normal levels for someone with celiac disease? Obviously 3 positive results point towards something.

I have never been on a gluten free diet for more than 2 weeks.

 

What happens if the biopsy comes back negative, what does this mean for my diet in the future?

Welcome to the club!

I would say that you have celiac disease. The gold standard for a final diagnosis is usually biopsies. Make sure they take up to six samples as the small intestine is vast (size of a tennis court). Keep eating gluten until the biopsies are done. Then check out our Newbie 101 section under "Coping" to help you REALLY go gluten free (cross contamination is a big deal for us)!

Also read the University of Chicago's celiac website. They are one of the leading researcher is the US, plus, their website is pretty nice.

Biopsy done and dusted. The dr said there was no visable damage she could see on the scope but have to wait for biopsy results. I'm a bit worried if it comes back as negative what to do seeming my blood test results were such high positives

I had no visible damage (I think this is common), but I had a Marsh Stage IIIB biopsy result which means moderate to severe damage.

The small intestine is vast (size of a tennis court), so damaged patches can be missed. With a high blood test result and a negative biopsy, the next step would be to go Gluten free for six months or longer.

Hang in there!

Like Cyclinglady said, damage is rarely visible during the endoscopy.  Sometimes there is a bit of redness, that's it.

 

With so many positive tests, and tests that are as much as six times over the normal limit, I would say that there is little doubt that you have celiac disease.  The tTG IgG does catch some celiacs, but it can miss as many as 60% of all celiacs.  Having a negative tTG IgG does not rule out celiac disease by any means.

 

This report discusses the tests (endoscopy and blood) from pages 7-12: Open Original Shared Link  As you can see, the tests are very specific to celiac disease.

 

If your biopsy does come back negative, which does happen to as many as 1 in 5 celiacs, it does not rule out celiac disease, it simply does not confirm the diagnosis.  Celiacs can have normal biopsies, but then they assume they are fine because not all tests are positive, so they continue to eat normally and damage their health further.  If you end up with a negative biopsy, you still probably have celiac disease and should go gluten-free.

 

If the biopsy is negative, you do have some options:

  1. Have the genetic testing done for DQ 2 and DQ8.  Over 97% of celiacs have those genes so if you don't have them there is a chance that you don't have celiac disease.
  2. Go gluten-free for at least 6 months and then retest your blood tests.  The DGP tests (deaminated gliadin peptides) are often used to test dietary compliance.  Those tests are often the first to respond to the gluten-free diet, and have often moved towards a normal result in the first 6 months.  The tTG IgA is generally slower to return to normal. It is not unusual for the tTG IgA to still be elevated after eating gluten-free for 6 or 12 months; it has usually at least started coming down in the first year gluten-free.  Do not retest sooner than 6 months because your autoantibodies may not have come down yet. Don't judge the diet's effectiveness on your symptoms before the first 6 months either.  Most people have symptoms that last a good 6 months, and some symptoms (like neuropathies, ataxia, nutritional deficiencies and anemia, comprehension issues, and arthritis) take a year or three to sort themselves out.

Good luck with the results!  :)

Hi all, update from me with my biopsy results which confirmed celiac disease. Hopefully now after 4 years of being told it was IBS I can get better. Very happy with my GI who actually seemed to care and knew what she was doing. Below is what my biopsy said. I'm interested in any of you guys that have been around a while and pick up anything on there that I might have missed when reading it.

MACROSCOPIC

A – GASTRIC BX – Two pieces of tissue measuring 3mm each. AE (2-1)

B – SMALL BOWEL BX – Six pieces of tissue ranging from 2-4 each. AE (6-1)

C – ILEUM – Five pieces of tissue measuring 2-3mm each. AE (5-1)

D – RECTAL BX – Two pieces of tissue measuring 1&2mm. AE (2-1/QZ/cy)

MICROSCOPIC

A – Sections show body type and antral type gastric mucosa with mild chronic gastritis. No small intestinal metaplasia is seen. Helicobactor-like organisms are not identified. There is no evidence of malignancy

B – Sections show small bowed (Duodenal) mucosa with crypt hyperplastic subtotal villous atrophy. There is a moderate chronic inflammatory infiltrate in the lamina propria including scattered lymphoid aggregates and prominent surface intraepithelial lymphocytosis. There is variable blunting of the villi. No organisms are seen. No granulomas are identified. There is no evidence of malignancy

Comment – The appearances are in keeping with celiac disease

C – Sections show small bowel (ileal) mucosa within normal limits including scattered peyer’s patches. No organisms are seen. There is no evidence of malignancy

D – Selections show colonic mucosa with scattered muciphages in the lamina propria and lymphoid aggregate. There is no evidence of malignancy

DIAGNOSIS

STOMACH: MILD CHRONIC GASTRIRIS

DUODENUM: CRYPTHYPERPLASTIC SUBTOTAL VILLOUS ATROPHY

ILEAL BIOPSY: NO SIGNIFICANT ABNORMALITY

RECTAL BIOPSY: NO SIGNIFICANT ABNORMALITY

Thank you for the update. It does seem you found yourself a really good GI doctor. 

Now you can get to the business of healing.

Do read the Newbie 101 thread at the top of the Coping section and ask any questions you need and we will try to help in any way we can.

I hope you heal quickly.

That's great he was so thorough!  Rather unusual... most have to fight to get at least 6 samples taken!

 

Well, at least you know the celiac disease diagnosis is definitely celiac disease (looks like marsh stage 3 damage - see page 9: Open Original Shared Linkand you can change things to get better.  :)

      Brown Rice Vinegar (organic) from Eden Foods is likely gluten free

      This is a solid, well-reasoned approach. You’re right that “koji” by itself doesn’t indicate gluten status, and the risk really does come down to which grain is used to culture it.

      Seven months can still be early in celiac healing, especially if you were mostly asymptomatic to begin with—symptoms like low iron, vitamin D deficiency, nail changes, and hair issues often take much longer to improve because the gut needs time to recover before absorption normalizes. A tTG-IgA of 69 is not “low” in terms of immune activity, and it can t...

      About Celiac Remission

      This idea comes up often, but it’s important to separate theory from what’s actually supported by evidence. In celiac disease, the immune system does not “forget” gluten in a permanent or reliable way, even after long periods of avoidance, and the celiac genes do not turn off. While antibody levels (like tTG IgA) can normalize on a strict gluten-free diet an...

      Gluten testing is normally reported in ppm (parts per million), which is equivalent to mg/kg, not micrograms by itself.

      Medications

      Medication sensitivity is very real for many people with celiac and other autoimmune conditions, and it’s frustrating when that’s brushed off. Even when a medication is technically gluten-free, fillers, dose changes, or how your nervous system reacts—especially with things like gabapentin—can cause paradoxical effects like feeling wired but exhausted.

The fact that you directly contacted Eden Foods and received a clear statement that their koji is made from rice only, with no wheat or barley, is meaningful due diligence—especially since Eden has a long-standing reputation for transparency. While the lack of gluten labeling can understandably give pause, manufacturer confirmation like this is often what people rely on for traditionally fermented products. As always, trusting your body after trying it is reasonable, but based on the information you gathered, your conclusion makes sense.

      Seven months can still be early in celiac healing, especially if you were mostly asymptomatic to begin with—symptoms like low iron, vitamin D deficiency, nail changes, and hair issues often take much longer to improve because the gut needs time to recover before absorption normalizes. A tTG-IgA of 69 is not “low” in terms of immune activity, and it can take 12–24 months (sometimes longer) for antibodies and the intestinal lining to fully heal, particularly in teens and young adults. Eating gluten again to “test” things isn’t recommended and won’t give you clear answers—it’s far more likely to cause harm than clarity. Weight not changing is also very common in celiac and doesn’t rule anything out. Please know that your frustration and sadness matter; this adjustment is hard, and feeling stuck can really affect mental health. You deserve support, and if you can, reaching out to a GI dietitian or mental health professional familiar with chronic illness could really help you through this phase. This study indicates that a majority of celiacs don't recover until 5 years after diagnosis and starting a gluten-free diet: Mucosal recovery and mortality in adults with celiac disease after treatment with a gluten-free diet However, it's also possible that what the study really shows is the difficulty in maintaining a 100% gluten-free diet. I suspect that if you looked closely at the diets of those who did not recover within 2 years might be that their diets were not 100% gluten-free. Perhaps they ate out more often, or didn't understand all of the hidden ingredients where gluten can hide. Either way, it shows how difficult recovery from celiac disease can be for most people. According to this study: This article explores other causes of flattened villi:

A result of <0.025 mcg only becomes meaningful if you know the sample size tested (for example, mcg per gram or per kg). If that value represents <0.025 mcg per gram, that would equal <25 ppm, which is above the gluten-free threshold; if it’s <0.025 mcg per kilogram, it would be extremely low and well within GF limits. Without the denominator, the result is incomplete. It’s reasonable to follow up with the company and ask them to confirm the result in ppm using a validated method (like ELISA R5)—that’s the standard used to assess gluten safety.

      Medication sensitivity is very real for many people with celiac and other autoimmune conditions, and it’s frustrating when that’s brushed off. Even when a medication is technically gluten-free, fillers, dose changes, or how your nervous system reacts—especially with things like gabapentin—can cause paradoxical effects like feeling wired but exhausted. The fact that it helped bloating suggests it may be affecting gut–nerve signaling, which makes sense in the context of SIBO, but that doesn’t mean the side effects should be ignored. You’re carrying a heavy load right now with ongoing skin, eye, and neurological uncertainty, and living in that kind of limbo is exhausting on its own. It’s understandable to feel overwhelmed and discouraged when systems and providers don’t meet you where you are—your experience is valid, and continuing to advocate for yourself, even when it’s hard, really does matter. You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

      I am not aware of an air detector for gluten, but Nima Partners sells a device that can detect gluten in minutes in a small sample of a meal or food that you eat. They are also a sponsor here for full disclosure: https://nimanow.com
