Test Results Confusion

5 posts in this topic

Ok, My older brother was just diagnosed with celiacs disease- he was off the charts, he advised that I go in and get testing based of my medical issues such as still births, miscarriages, radical thymectomy due to the starts of myasthenia gravis. So, I went on Monday and got my results today- the Dr. said it was negative: I am however confused on the findings.

I am 34 years old, here is the results given: Can any of you help me with this- do I have it or not?

Deamidated Gliadin Peptide Ab IgA mine was a 4

Deamidated Gliadin Peptide Ab IgG mine was a 7

Tissue Transglutaminase Ab, IgA mine was a 19 they said the range for this is from 0-19

Tissue Transglutaminase Ab, IgG mine was a 6

so according to the other numbers they are low representing negative, but the Ab,IgA has me confused: I went to my primary care dr. there is no way I have the money right now to get the endo. What are your opinions and or what does this mean, I am SO confused.


Can anyone please help me with my test results.

You need to include the reference ranges when you post results. Every lab is different.

maybe the normal range is from 0-10 and 11-19 ia grey zone, and 20 definitely positive.

In early celiac, the damage is patchy and about 50% test negatiive. That is because the blood test are designed to only turn positive when there is a lot of damale, like total villous atrophy....they really want to avoid getting positive reaults for people that are just at the beginning of celiac.

I think this has to do with Europe, like in many countries patietns get money from the government if diagnosed celiac.

So the rules have to be strict and apply to all the world.

So they set the cutoff of the blood tests very high to only catch very ill celiacs.

So I think your result of 19 really means something, and that they should do a biopsy.

Your other symptoms , and the fact that your brother was diagnosed, really suggest celiac.

The most important celiac test here amongst all the tests, is the Ttg IgA test.

In many countries that is the only one they run (together with the total IgA to check if people make enought IgA at all so the test is valid or not, otherwise they do the IgG version)

I would strongly advise you to try the diet after you have finished all the testing you want to have done. There are false negatives on testing, I was the sickest person in my family and always showed a false negative on testing but all my other family members, including ex-husband showed positive. A good strict trial of the diet may be of more value for you.

    • Hi Ironic Truth, Thanks for Replying. Wow I get bad joint pain too. So my opinion especially if he is eating gluten is to get him tested. I wish I had been tested when I was eating gluten 8 years ago .  I had tried 8 years ago initially to figure out what the heck was going on with me and my immune system. I started with a GP, went to Allergist/Immunologist etc. I gave up 4 doctors later when nothing seem to be found and you sense they start thinking lady you're a nut job . My cousin a diagnosed Celiac took over 2 years to be diagnosed and she is a nurse. My husband said for years "I think bread is bad for you" and in a desperate attempt to help myself -I gave up wheat after 2 weeks felt better 2 months later I went total gluten-free and felt very much better that was 4 years ago. So I have suspected NCGS or Celiac for a few years now. However getting someone to test you for it when you were classified IBS 20 years prior-well as is chronically heard on the forums here is perhaps the biggest challenge of all. One then just finally says ok I will just try this gluten-free thing myself. I was gluten-free for 3 1/2 years and improving. Then  I got gluten-ed in March of 2016 and I had worse symptoms then ever the joint pain arrived. I went to a new allergist who refereed me to another Allergist/Immunologist who deals with Celiacs and Food Intolerances. I did see a Rheumotologist in July 2016 since the muscle and joint pain was still lingering, who tested me and reported no antibodies. Back to the specialist who did more test and suggested the gluten challenge. It's likely me failing to complete 2 weeks caused it but the symptoms got real bad and I thought I'm going to have worse issues if I don't stop this.  Today my fingers are just starting to heal they were peeling during the gluten challenge among all the other symptoms I get, which I attribute to dehydration. The dry peeling fingers did not improve until I got the IV the day of the scope. Bizarrely I was looking forward to the scope hoping I'd get an IV with Meds and fluids becaus eI felt I needed it. I did see one abstract, I can't get my hands on the full article as you stated their is a link: Dig Dis Sci. 2005 Jan;50(1):126-9. Celiac disease and intestinal metaplasia of the esophagus (Barrett's esophagus). Maieron R1, Elli L, Marino M, Floriani I, Minerva F, Avellini C, Falconieri G, Pizzolitto S, Zilli M So I will pursue the path of monitoring the  Barrett's. Despite no official diagnosis for me, you are right Gluten is bad for me, I should avoid it, I will, and I'll stay on the forums. Good luck with you Boyfriend he is lucky to have you looking out for him.
    • Hi Sunshine, There is a program called a 504 plan that some schools will follow if you get one approved.  It helps the school identify proper ways to deal with a child's particular needs.  Probably it is helpful to have a 504 plan, but they may require a formal diagnosis for it.  I suggest you talk to the school and ask them about it.  Tell them the situation with the kid and about the stress he would need to go through to get diagnosed.  They may be willing to work with you without a formal diagnosis.   I am not saying you absolutely have to have a 504 plan for him.  School districts vary and some may be more accommodating than others.  A 504 plan may give you certain rights, but I  am no expert on them. The gluten challenge is 12 weeks of eating gluten for blood tests.  The payback for being formally diagnosed is questionable IMHO.  Treatment is the same regardless, eating gluten-free for life.  One thing to be aware of is that celiac disease has a genetic factor.  So he got the gene from one of the parents.  Anyone else in the family could have celiac develop at some point.  So testing every couple years for all family members is a good idea. Welcome to the forum!
    • Thank you everyone. I appreciate all of the information and support.  I am feeling overwhelmed right now and it was really getting me down yesterday. I don't feel so hopeless now. 
    • Okay. I think I will start with an allergist and a dietitian. 
    • Yes, that list I posted includes stuff to look out for in your cosmetics as well, I think. Spices get contaminated often depending on brands, sources, and packaging plants, you have to find brands that are certified, I find Spicely Orangics works here. Supplement wise I am on a ton. I take combinations of Liquid Health Brand, Stress & Energy and Neurologic Support for B-Vitamins, I take Doctors Best Chelated Powdered Magnesium. I drink a bunch of almond milk and eat a lot of nuts, seeds, green leafy veggies, and a huge viarity of foods always having a mix to balance out my needs in vitamins (I studied alot an worked with a dietician to learn what contains what and find my balance). I found a IBS targeted probitotic from jarrow seems to work best with me and no bloat. List of other supplements if you want but with celiacs different people can get different deficiencies and you should probably talk to a dietician and see about having your own regiment built up. I just listed the common ones. I was thinking about this later on and after I got off the stuff for awhile I found myself randomly vomiting from some foods, none of the brain fog, numbness, Just throwing up. Ended up I developed intolerance to certain foods like egg yolks, soy, and a few others things. I also developed allergies to corn where I would just get sores in my mouth and digestive tact and run 99-102F Fevers when I ate anything contaminated with it. And a peanut allergy that caused me to distend and swell throwing up for hours and getting a rash later on. My different reactions to different foods made my dietician laugh at how odd my body is (we both did after talking for awhile) and my doctors found it interesting and kept on wanting to run more test.
