Help understanding results

Just been to my consultation with my GP and have been referred. 

My results are as follows:

Tissu transglutaminase lGA level: 130 u/ml. Range 0.00 - 2.9u/ml

Endomysial antibody lGA level. Weak positive. No figures for that? Is that a visual test perhaps? 

Any assistance in understanding the figures would be great.

Just as the nurse hinted.....you have celiac disease!  Normally, biopsies (obtained from through an endoscopy) would officially confirm it, but you will have to decide if you want to go that route.  Easy for me as it was covered by insurance and I did not have to wait long.  Not so easy in countries where there often is a long wait.  I also just had anemia so I was not suffering at all even though I had moderate to severe intestinal damage.  I needed a firm diagnosis for that reason.  Also my husband (not officially diagnosed) had been gluten free for 12 years and I could not believe that I would have it too!   I encourage you to research further and decide what is best for you.

The tTG IgA typically indicaes and autoimmune attack is happening in the mucosal lining of the intestines.  You are over 40X the upper limit.  That's about as positive as it gets.

The EMA IgA is similar to the ttG IgA but it tends to show more advanced disease.  It is not uncommon to have a positive tTG IgA and a negative EMA IgA, but it is very unusual to have a positive EMA IgA without a positive tTG IgA.  The EMA IgA often starts in response to the tTG IgA damaging the intestines. It attacks and tries to wipe out the upper layer of the intestines.

The EMA IgA is done as a titre.  They keep diluting the sample until it is undetectable.  A positive is often 1:80 or 1:160 (1:320 is very positive). 1:40, 1:20, 1:10 are considered negative usually (1:40 could be a positive in some places).  So yes, it is a visual test.

Those are the positives I had too.

Cyclinglady, thanks. My GP suggested getting the gastro privately as it will speed things up a lot, then the biopsy on the NHS. 

NVSMOM, yet again you're a fountain of knowledge, helping alleviate my concerns. Now I've had the positive blood, I'm worried I'll have a negative biopsy, but your post has helped me believe that maybe I will get a positive diagnosis, thanks.

Ha!  I was just going to tell you to google the content of your question, but NVSMOM actually keeps this information in her head!  Amazing!  ?

LOL  I'm at a good level of geekiness in those tests because they were relevant to my situation. Self serving interest. ;) :)

There is a chance you'll have a negative biopsy.  Damage can be patchy, although a positive EMA IgA is usually a positive biopsy.

The false negative rate for biopsies can be as high as 1 in 5, or 20%.  That seems to happen most early in the disease, if the damage is patchy, and if fewer than 6 samples were taken.  If you do get it done, make sure they start at 6 samples - more is better.

I am going to push hard for 6+ samples. As I cannot imagine how bad I'll feel getting a negative result. I need some answers and a chance of a life without exhaustion. 

Since my last post, I've had a few upsetting realisations. My mum has had a life of symptoms much the same as mine, but hers have progressed to osteoporosis, carpal tunnel, etc. 

We were chatting about it all and my mum talked about her IBS, I told her she doesn't have IBS, she has Celiacs and that the IBS was a misdiagnosis. She said "well your nan had IBS too", at which point suddenly dots connected in my mind and a cold shiver went through my body. My nan died of intestinal cancer. 

So it looks highly likely my nan lives with Celiac, undiagnosed, as did my mum and as have I. My mums health has declined rapidly but she's agreed to go completely gluten free for the rest of her life. Realising my nan probably died of it, plus her symptoms and my recent bloods, she's 99% convinced that she has it. 

She isn't going to have the tests, as she will not have an endoscopy. Long story short, my grandad had one, which punctured his oesophagus, leading to him being given morphine, which lead to pneumonia and he died. So I understand why she's terrified. 

Plus, it will be several more months of declining health. So nothing to lose by going gluten free. I am hoping this changes things for her.

i have a gastro appointment on November 3rd and hoping a biopsy not long after! Fingers crossed.

No reason for your rmum to go through an endoscopy then. She could still get the blood work but if she's content to go strict gluten-free then good for her. Make sure she reads or you teach her everything in the Newbie 101 so she knows how to protect herself from cross contamination. And tell her she might go through gluten withdrawal but it will only last 1 month max. if that (for most people). All your first degree relatives should get tested every 2 years or sooner if symptoms present as celiac can present at any age.

Fingers crossed for you to get an endoscopy very soon! Please let us know what happens at the gastro.

I agree. Let your mom (and siblings) know that they can just have the blood test. An endoscopy is not an absolute need for a diagnosis - I've never had one done either.

Good luck.

      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.

      I had no idea there is a "Louisville" in Colorado!😉 I thought it was a typo because I always think of the Kentucky city--but good luck!

      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.
