Help - TTG IgA 192.2. What does it mean?

Hi everyone, 

I'm just looking for a bit of help. Firstly I never expected to be Coeliac or have any issue with Gluten. I do have some of the symptoms including pain etc. but never once suspected Gluten. 

 

After some tests my doctor recommended a test and the results have come back what appears to be very high levels of TTG. The NHS app says I have, "tissue transglutaminase igA lev 192.7 K/UL". It also says the normal range is 0.0 - 14.9.

I've not got to wait 4 weeks for a phone appointment with my doctor before I can find anything out of next steps. The app says consider Endoscopy and a Jujunal Biopsy. But it's just notes from the lab and not information from my doctor. I really have no idea what to expect as the levels I've seen others talk about are much lower.

It's been a few days since my phone appointment was booked, but i can't stop worrying/thinking about it and i have weeks before i can speak to someone about the results. I was hoping someone here may be able to shed a little information. 

Thank you and my apologies for the long post.

Your test results indicate that you are almost 13 times the cutoff level for a positive celiac disease test, which means you most likely have it. In the UK and other places many doctor now diagnose celiac disease without a biopsy/endoscopy when you are 10x or more that the cut off, so you may not have to undergo that procedure depending on what your doctor says. 

This article might be helpful. It breaks down each type of test, and what a positive results means in terms of the probability that you might have celiac disease. One test that always needs to be done is the IgA Levels/Deficiency Test (often called "Total IGA") because some people are naturally IGA deficient, and if this is the case, then certain blood tests for celiac disease might be false-negative, and other types of tests need to be done to make an accurate diagnosis. The article includes the "Mayo Clinic Protocol," which is the best overall protocol for results to be ~98% accurate.

Thank you Scott. I really appreciate you taking the time to reply. I'm going to ask for the Endoscopy if I can have it, as I've read bloods aren't 100%. I'm also going to call the doctors up today and push for an earlier phone consultation. 

Thank you again.

Hi Joel, 

Just saying 'hi' as I'm a UK Coeliac.

When my first blood tests pointed to coeliac disease, my local NHS lab didn't disclose tTG readings if they were over 100, the paperwork would just return the results as '>100'.  It is great that you have a lab which reports on the numbers as accurately as that, it will be very helpful as the months go by for you to monitor your progress.   

Also to reassure you that having been on this forum now for ten years, I have learned it isn't uncommon to have levels higher than 100 as an undiagnosed/non-diet compliant coeliac.

Remember you must continue to eat gluten right up until your endoscopy (if you have to have one).  It is recommended that you consume 2 slices of normal (i.e. glutenous) bread every day, or the equivalent.  When I was awaiting my test, I made the most of eating some of the gluten containing foods I knew I'd miss once on a gluten free diet.  But on the positive - should you be a coeliac, a lot of that food that I thought I'd never eat again (such as Weetabix) now has a gluten-free equivalent.  But I am still waiting for McVities to manufacture gluten-free Penguin bars!😊

Hi Christina,

 

Thank you so much for taking the time to reply with such encouraging info. I think I'm still in a bit of denial about it all. I'm 39 and all I eat is gluten. I think I'm that used to stomach pains etc. I've just thought it's a normal part of the day. Not this has been brought to my attention I'm a lot more aware of feeling bloated and having stomach pains. This is making me think i could have Coeliac but again I'm so surprised as I don't have many of the symptoms. Or maybe I do, but again I just think it's normal and not major like others must have.  It was only when I had spells of extreme pain and fatigue that I got a bit concerned, but even then it was others who forced me to get checked out (Im a typical daft male who refuses to go to the doctor normally). 

 

As for the food, it's amazing seeing all the gluten free options. I've heard in the UK we have some of the best shop breads etc. too. So that's lucky for us. We need to campaign for those penguins though haha. I've looked at options in case I do have coeliac but as you say I'm sticking to a full gluten diet for now. I've had my GP phone appointment moved forward a week so hopefully I'll have some answers in a few weeks for next steps.

 

Thank you again. I have a feeling this community is going to be a new home for me.

Hi Joel

You are more than welcome.  This forum has been an absolute lifesaver to me, I've said to @Scott Adams that if we lived in the UK I think he would have been to Buckingham Palace by now to receive an award! 

Apart from this site, I would recommend you take a look at the Coeliac UK website for UK specific advice.  It would be money well spent if/when you are formally diagnosed to join Coeliac UK, as they have a really good Food and Drink Directory and also an app which will help you round the foo d aisles at Tescos, etc.   Obviously, a lot of fresh food and drink is naturally gluten free, and a lot of food in tins and packets is also gluten free although not necessary certified gluten free  - this is where this directory comes in handy.

As for the Penguins, yes, let's start a petition!  However, what I will say is Tescos do some extremely chocolatey biscuits which are absolutely delicious, and, dare I say it, probably every bit as good - the only problem is they aren't individual wrapped and melt in your hand when you eat them!

Anyway, very nice to meet you.  Keep us posted!

      @Jmartes71, Please do get checked for nutritional deficiencies.  A good B Complex, Vitamin D, Benfotiamine (a form of Thiamine Vitamin B1 that promotes intestinal healing), Vitamin D and magnesium are a good way to start. Correcting nutritional deficiencies with Thiamine supplements (like Benfotiamine), B Complex, and Vitamin D were my miracles. How are you doing?  Sending prayers.

      Waiting on biopsy after positive bloodwork, but also not really believing this is real

      By knitty kitty · Posted

      @Alibu, I think you should send the National Institute of Health peer reviewed studies I linked to your doctors.  Some doctors don't keep abreast of the recent updates to Celiac diagnosis.  They may still be operating under the old idea of waiting until intestinal damage is at a Marsh score of 3C or 4 (complete villus atrophy) before diagnosis of Celiac is made.  Better to diagnose before it gets that severe.   Much of the damage to the small intestines is microscopic and NOT visible to the naked eye.   Since you've got Celiac genes, it would be beneficial if you kept to a strict gluten free diet.  Exposure to gluten and an environmental stress (like an infection or physical stress or emotional trauma) are needed for the Celiac genes to become activated.  If you don't have active Celiac now, a gluten free diet now will help prevent developing it in future.

      @knitty kitty Thank you for your response!!  So do you think my doctor might still diagnose celiac even with the negative biopsy?  At this point I'm just wondering like do I have to be super careful when I eat places for cross-contamination, or do I just have to eat gluten free and not worry about the damage so much as the symptoms, you know?  Like with celiac I know my body is attacking itself and doing damage (although apparently not haha) and with an intolerance it certainly doesn't feel good, but it's not doing the same kind of damage, you know? I sent a message to the doctor asking if I should do a video capsule endoscopy or if we should have a second opinion on the pathology but ugh, I just want a clear answer so whatever it is, I can move forward!!

      Newly Diagnosed

      Welcome to the forum, @Gary Libby! Have you talked to your doctors and nutritionist about checking for nutritional deficiencies and supplementing with vitamins and minerals while you're healing?   Malabsorption caused by the inflammation and damage of celiac disease can deplete our stored vitamins, making us feel poorly the majority of the time.  The B vitamins are needed to digest our food and turn it into energy for our body to function.  If we're not able to absorb nutrients from food, taking a B Complex vitamin supplement can help immensely.  Do get checked for deficiencies before starting supplements.  Ask for an Erythrocyte Transketolace test.   Consider folliwing the Autoimmune Protocol diet to help your intestines heal.  Benfotiamine, a form of thiamine Vitamin B1, has been scientifically shown to promote intestinal healing.   Hope this helps and you feel better soon!  Keep us posted on your progress.

      Probably celiac but also confused

      By knitty kitty · Posted

      @terrymouse, I agree that you may be suffering from nutritional deficiencies already.  Get tested for nutritional deficiencies before supplementing, otherwise the vitamins you're taking can mask a deficiency.   Symptoms that you have are similar to what I experienced with malabsorption of Celiac Disease.  I would lose my appetite; if I did eat, I got full quickly, and had nausea, dizziness, trouble digesting fats, abdominal pain, and heart palpitations.  I had unintentional weight loss.  I also had my gallbladder removed.  I was deficient in the essential nutrients, especially Thiamine and the other B vitamins. Ask for an Erythrocyte Transketolace test.  Thiamine deficiency symptoms may appear first because our body can't store it for more than three weeks and our metabolic needs for Thiamine increase when we're physically sick or emotionally stressed, so we can become depleted quickly.  Thiamine deficiency symptoms include gallbladder problems and all the ones list above.  Thiamine and the other B vitamins are needed to digest our food and turn it into energy for our body to function.  Gastrointestinal Beriberi is frequently overlooked by doctors.   Ask for a DNA test to check for any known genes for Celiac Disease.  You have to have at least one gene for celiac disease to develop.  You don't have to be eating gluten for a DNA test.  Your genes don't change.  If you don't have any celiac disease genes, you can focus on other reasons for your illness.  If you do have celiac disease genes, with your positive blood test results, you, your doctors and nutritionist can focus on correcting nutritional deficiencies which will help you heal and feel better.
