Tissue Transglutaminase Test Results

Hi everyone,

My Tissue Transglutaminase IGG and IGA results came back tonight and it came back negative:

TISSUE TRANSGLUTAMINASE IGG 0.39 <0.90-Index

TISSUE TRANSGLUTAMINASE IGA 048 <0.90-Index

I have been having the typical symptoms of Celiac Disease, but wasn't sure if it was from a medication for my diabetes. My doctor ordered for these tests to be done after 9 months of being on the medication and having constant diarrhea (up to 3-4 times a day), stomach making noses, painful cramps, nausea, vomiting, etc. The medication's side effects was only diarrhea and that should have subsided in 3-4 months after being put on it as my body got used to it. However, even previous to being on this medication, I always had problems with food and my stomach, but never thought too much into it.

Since I have been off the medication 1 1/2 weeks ago and am still eating some type of gluten each day (since I heard you should stay on a gluten diet in case a biopsy needs to be done), I have not had diarrhea or stomach cramps until TODAY. And, it was strange to me, that I ate a pastry and was immediately knocked out and slept for 1 1/2 hours during the day. This hasn't happened since I've been off the medication and stopped eating huge amounts of gluten at once.

Anyways, I was comparing others' negative result values with mine. I'm noticing that many had lower IGG and IGA results than mine. For example, an IGG result of 0.11 and IGA of 0.21. Both of my results are higher than the ones that I've compared with online. Does this make any difference even though mine and another's are less than the standard range of <.90 (as made by Kaiser)? As in, does my higher results mean that I may have a higher possibility of being gluten intolerant vs someone who has lower results? Or does it not matter since it's lower than the standard range.

I apologize if these questions may sound like I'm crazy. I'm not looking to be diagnosed with this (who does?), but I'd just like to have an answer to why I may be having these symptoms. It would make me feel better just knowing that I may have some sensitivity to gluten, but not be officially diagnosed with celiac disease..and not just be clueless!

Thanks!

Jackie

Did your doctor run the antigliadin tests also or just the TTG?

Just the TTG. I've written to her to let her know that my symptoms have come back, but am waiting for her response. I am hoping that she will run other tests rather than my initiating it, but I will if necessary.

After you are done with all testing do give the diet a try as false negatives are not uncommon.

Everything below the standard range is noise. The standard range is not zero because there is always some random background noise in this kind of assay. You also can't compare your numbers to anyone else because labs have different ways to score the assay. You're comparing apples to oranges.

It's really good you don't have TTG. Autoimmunity is no fun. You'll just have to pay attention to your body and how you feel after you eat gluten.

      Celiac and allergic to common subs and adds in prepared foods

      By DAR girl · Posted

      Looking for help sourcing gluten-free products that do not contain potato or corn derived ingredients. I have other autoimmune conditions (Psoriatic Arthritis and Sjogrens) so I’m looking for prepared foods as I have fatigue and cannot devote a lot of time to baking my own treats.

      Disregarded

      By Scott Adams · Posted

      I am so sorry you're going through this. It's completely understandable to feel frustrated, stressed, and disregarded after such a long and difficult health journey. It's exhausting to constantly advocate for yourself, especially when you're dealing with so many symptoms and positive diagnoses like SIBO, while still feeling unwell. The fact that you have been diligently following the diet without relief is a clear sign that something else is going on, and your doctors should be investigating other causes or complications, not dismissing your very real suffering.

      Paying for my own Celiac screening at WalkInLab so a positive result doesn’t become part of my medical history

      By Oldturdle · Posted

      It is just so sad that health care in the United States has come to this.  Health insurance should be available to everyone, not just the healthy or the rich.  My heart goes out to you.  I would not hesitate to have the test and pay for it myself.  My big concern would be how you could keep the results truly private.  I am sure that ultimately, you could not.  A.I. is getting more and more pervasive, and all data is available somewhere.  I don't know if you could give a fake name, or pay for your test with cash.  I certainly would not disclose any positive results on a private insurance application.  As I understand it, for an official diagnosis, an MD needs to review your labs and make the call.  If you end up in the ER, or some other situation, just request a gluten free diet, and say it is because you feel better when you don't eat gluten.      Hang in there, though.  Medicare is not that far away for you, and it will remove a lot of stress from your health care concerns.  You will even be able to "come out of the closet" about being Celiac!

      Yes, I've posted a few times about two companies: Request a Test and Ulta Labs. Also, pretty much we can all request any test we want (with the possible exception of the N protein Covid test and I'm sure a couple of others) with Lab Corp (or Pixel by Lab Corp) and Quest. I much prefer Lab Corp for their professionalism, ease of service and having it together administratively, at least in DC. And just so you know, Request a Test uses Lab Corp and Quest anyway, while Ulta Labs uses only Quest. Ulta Labs is cheaper than Request a Test, but I am tired of dealing with Quest, so I don't use them so much.

      Does Dailymed.nlm.nih.gov site have filters for gluten?

      By Scott Adams · Posted

      PS - I think you meant this site, but I don't believe it has been updated in years: http://glutenfreedrugs.com/ so it is best to use: 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/
