New here! Very confused by test results! High TTG/Negative Biopsy

I am very confused by my test results that I received and was hoping for some clarification and answers to some questions that I have! In November of 2017 I had a celiac disease panel done. These are my results:

Name: IgA     My value: 401    Reference range: 68-408

Name: TTG Ab IgA     My value: 71      Reference range: 0-3

This information was included under my test results:

No further celiac testing to be performed.
- INTERPRETIVE INFORMATION: Tissue Transglutaminase (tTG)
- Antibody, IgA
- 3 U/mL or less: Negative
- 4-10 U/mL: Weak Positive
- 11 U/mL or greater: Positive
- Presence of the tissue transglutaminase (tTG) IgA antibody is
- associated with glutensensitive enteropathies such as celiac
- disease and dermatitis herpetiformis. tTG IgA antibody
- concentrations greater than 40 U/mL usually correlate with
- results of duodenal biopsies consistent with a diagnosis of
- celiac disease. For antibody concentrations greater or equal to
- 4 U/mL but less than or equal to 40 U/mL, additional testing for
- endomysial (EMA) IgA concentrations may improve the positive

- predictive value for disease.

After these results my GI doctor wanted me to have an endoscopy and a colonoscopy. I had these procedures done on January, 24th. Today I received a call from the nurse and she told me that my colon biopsies were normal as well as the biopsy the doctor did of my duodenum. She said that I tested negative for celiac disease. She also said that the biopsy done of my esophagus showed that I have esophageal candidiasis. I was prescribed Diflucan. Now, I am very confused! I have terrible stomach pain, fatigue, back pain, weight loss (20 lbs) and diarrhea. This has been going on for quite some time hence why I went to the GI in the first place. I don't understand what is going on with me! So, my questions that I was hoping someone could answer are:

What else can cause an elevated TTG? Could it be the esophageal candidiasis that caused the elevated TTG? Is it possible that I do actually have celiac disease even though my duodenal biopsy came back normal?

I was so hoping for some answers from these tests as I have not been feeling good for some time and would really love to get on with my life! I am a 27 year old female and I have a 4 year old son, I would love to be able to do all the things he wants to do without feeling terrible while doing them!

Also, I have an appointment with my GI tomorrow, any suggestions as to what questions I should ask besides the questions I have asked here? I really want to walk out of her office tomorrow and have some answers!!!

Thank you so much for reading and helping me interpret some of this mess!

Kristie,

Sadly, the diagnosis of celiac disease is often confusing.  I'm an ob/gyn, so I don't have formal training in this by any means.  Though I have celiac disease so I try to stay up to date on things.

I'm not aware of anything else that could cause elevated TTG antibodies.  Your GI only took 1 duodenal biopsy, though did several colonic biopsies?  I think usually they need to take multiple duodenal biopsies because it can be easy to miss a lesion in the duodenum.  Also, the GI doc may consider doing genotyping as the biopsies do not match up with the blood testing.

Good luck.  Autoimmune disorders can be very confusing.  Thankfully it is getting easier and easier to eat gluten free!

Consider confirming with the GI as to exactly how many biopsies were taken and their location.    Get a copy of the pathologist’s report, the endoscopy notes, and your lab results from the blood tests as you may want to get a second consult and it is good to keep for life!  

I can tell you that during my last endoscopy (after being gluten-free for five years), my GI only took one biopsy from the doudenum.  Why?  Because his lastest and greatest scope could visually see tons of villi and he went down far.  The newer scopes do have great magnification.  That said, your damage could be much lower and beyond the reach of either scope.  That happened to my niece who does not have celiac disease but was diagnosed with Crohn’s via a pill camera.  

Sime things can slightly elevate the TTG, like other autoimmune disorders or maybe even Lyme Disease, but your result is very high.  

He might suggest a pill camera, a gluten-free diet trial, retesting your TTG to see if it was a false positive or run the entire celiac panel to include the EMA and DGP tests.  Talk about your Candida issue too.  What might be the root cause of that?  It could be the source of your current symptoms.  I went back for my endoscopy because my DGP antibodies had been elevated last winter and I could not tell if they were going down or up when I retested in the Fall.  I am super strict with my diet and I needed to know why I was feeling sick.   My small intestine is healed, but I have chronic gastritis (autoimmune).  So, celiac disease was not the culprit.  

I hope this helps with your doctor visit (and let me disclose that I am NOT a doctor).

ZobGuyn,

I'm sorry I should have specified! My EGD procedure report states: Duodenal biopsies were obtained to evaluate for celiac disease.

So, more than one biopsy was taken. I too am not aware of anything else that causes elevated TTG antibodies, I plan on asking my GI about it tomorrow!

Thank you so much for your response!

Cyclinglady,

I will absolutely confirm with my GI about how many biopsies were taken. I have my EGD procedure report that states: Duodenal biopsies were obtained to evaluate for celiac disease.  Duodenum was normal upon examination. So, I'm assuming that more than one biopsy was taken. The procedure report also states that: The Olympus video endoscope was advanced to the 2nd portion of the duodenum without difficulty. There were no immediate complications.

Findings were as follows: The Z-Line was located at 40 cm from the incisors. The gastric folds began at 40 cm from the incisors. The diaphragmatic hiatus was 40 cm from the incisors.

I do plan on bringing up the Candida issue tomorrow as well. I want to know if that could be the cause of all of my symptoms and the elevated TTG. I plan on asking to have my blood work retested tomorrow. My goal is to walk out of my GI doctors office with ANSWERS! Lol! I learned that I have to be my own advocate! My primary doctor is a piece of work and I've learned from being her patient that I need to speak up and ask questions.

It's been a crazy few months and I am ready to start feeling better! It's been years of bowel movement issues and in September it came to a head! I was in so much pain I went to the ER because I thought I had appendicitis. A CT scan showed that I didn't have appendicitis but that I had colitis. My white blood cell count was slightly elevated at the time. I was prescribed ciprofloxacin and flagyl. Neither one of them helped at all. I am just beyond confused with everything! Thank you so much for your response!

      Taken Seriously

      By Scott Adams · Posted

      Your post demonstrates the profound frustration and isolation that so many in the Celiac community feel, and I want to thank you for channeling that experience into advocacy. The medical gaslighting you endured for decades is an unacceptable and, sadly, a common story, and the fact that you now have to "school" your own GI specialist speaks volumes about the critical lack of consistent and updated education. Your idea to make Celiac Disease a reportable condition to public health authorities is a compelling and strategic one. This single action would force the system to formally acknowledge the prevalence and seriousness of the disease, creating a concrete dataset that could drive better research funding, shape medical school curricula, and validate the patient experience in a way that individual stories alone often cannot. It is an uphill battle, but contacting representatives, as you have done with Adam Gray, is exactly how change begins. By framing it as a public health necessity—a matter of patient safety and protection from misdiagnosis and neglect—you are building a powerful case. Your voice and your perseverance, forged through thirty years of struggle, are exactly what this community needs to ensure that no one else has to fight so hard just to be believed and properly cared for.

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

      By Scott Adams · Posted

      Navigating medication safety with Celiac disease can be incredibly stressful, especially when dealing with asthma and severe allergies on top of it. While I don't have personal experience with the HealthA2Z brand of cetirizine, your caution is absolutely warranted. The inactive ingredients in pills, known as excipients, are often where gluten can be hidden, and since the FDA does not require gluten-free labeling for prescription or over-the-counter drugs, the manufacturer's word is essential. The fact that you cannot get a clear answer from Allegiant Health is a significant red flag; a company that is confident its product is gluten-free will typically have a customer service protocol to answer that exact question. In situations like this, the safest course of action is to consider this product "guilty until proven innocent" and avoid it. A better alternative would be to ask your pharmacist or doctor to help you identify a major national brand of cetirizine (like Zyrtec) whose manufacturer has a verified, publicly stated gluten-free policy for that specific medication. It's not worth the risk to your health when reliable, verifiable options are almost certainly available to you. You can search this site for USA 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/

      Protein or fat?

      By Scott Adams · Posted

      What you're describing is indeed familiar to many in the Celiac community, especially in the early stages of healing. When the intestinal villi are damaged from Celiac disease, they struggle to properly digest and absorb fats, a condition known as bile acid malabsorption. This can cause exactly the kind of cramping and spasms you're seeing, as undigested fats can irritate the sensitive gut lining. It is highly plausible that her reactions to dairy and eggs are linked to their higher fat content rather than the proteins, especially since she tolerates lean chicken breast. The great news is that for many, this does improve with time. As her gut continues to heal on a strict gluten-free diet, her ability to produce the necessary enzymes and bile to break down fats should gradually return, allowing her to slowly tolerate a wider variety of foods. It's a slow process of healing, but your careful approach of focusing on low-fat, nutrient-dense foods like seeds and avocado is providing her system the best possible environment to recover. Many people with celiac disease, especially those who are in the 0-2 year range of their recovery, have additional food intolerance issues which could be temporary. To figure this out you may need to keep a food diary and do an elimination diet over a few months. Some common food intolerance issues are dairy/casein, eggs, corn, oats, and soy. The good news is that after your gut heals (for most people who are 100% gluten-free this will take several months to two years) you may be able to slowly add some these items back into your diet after the damaged villi heal. This article may be helpful: Thank you for sharing your story—it's a valuable insight for other parents navigating similar challenges.

      Diagnosed celiac for 1-2 months ago and everything makes me bloated.

      By Beverage · Posted

      I had a very rough month after diagnosis. No exaggeration, lost so much inflammatory weight, I looked like a bag of bones, underneath i had been literally starving to death. I did start feeling noticeably better after a month of very strict control of my kitchen and home. What are you eating for breakfast and lunch? I ignored my doc and ate oats, yes they were gluten free, but some brands are at the higher end of gluten free. Lots of celics can eat Bob's Red Mill gluten-free oats, but not me. I can now eat them, but they have to be grown and processed according to the "purity protocol" methods. I mail order them, Montana Gluten-Free brand. A food and symptoms and activities log can be helpful in tracking down issues. You might be totally aware, but I have to mention about the risk of airborne gluten. As the doc that diagnosed me warned . . Remember eyes, ears, nose, and mouth all lead to your stomach and intestines.  Are you getting any cross contamination? Airborne gluten? Any pets eating gluten (they eat it, lick themselves, you pet them...)? Any house remodeling? We live in an older home, always fixing something. I've gotten glutened from the dust from cutting into plaster walls, possibly also plywood (glues). The suggestions by many here on vitamin supplements also really helped me. I had some lingering allergies and asthma, which are now 99% gone. I was taking Albuterol inhaler every hour just to breathe, but thiamine in form of benfotiamine kicked that down to 1-2 times a day within a few days of starting it. Also, since cutting out inflammatory seed oils (canola, sunflower, grapeseed, etc) and cooking with real olive oil, avocado oil, ghee, and coconut oil, I have noticed even greater improvement overall and haven't used the inhaler in months! It takes time to weed out everything in your life that contains gluten, and it takes awhile to heal and rebuild your health. At first it's mentally exhausting, overwhelming, even obsessive, but it gets better and second nature.
