Celiac Or Not? What Do My Test Results Mean?

I got my celiac panel done after my cousin was diagnosed with celiac disease a couple months ago.. I have had a ton of the symptoms for a long time.. here are my results what does this mean?.. all the GI doctor said is that I need a biopsy so I will be having that in a couple weeks. I got confused since I was positive on 2 and negative on 2..

immunoglobulin A Serum 140 range 70-400

deamidated Gliadin Abs, IgG 36 range is 0-19 negative, 20-30 weak positve, greater than 30 moderate to strong positive

deamidated Gliadin Abs, IgG 46 range is 0-19 negative, 20-30 weak positve, greater than 30 moderate to strong positive

t-transglutaminace tTG IgA <1 range is 0-3 negative

t-transglutaminace tTG IgG 4 range is 0-5 negative, 6-9 weak positive, positive >9

I also had low vitamin D levels and was slightly anemic.. thanks for any feedback! :)

Hello and welcome, Kate.

The Deamidated Gliadin Peptide test is the newest and most specific for celiac of all the tests in the celiac panel (your doc did not run them all but it's good that he did the DGP :) ). Even though your tTG tests were negative, I would trust the DGP and consider myself a diagnosed celiac. But doctors normally want to "confirm" the diagnosis with the biopsy. You do not have to test positive on all blood work to be considered celiac positive. Your low levels of D and your slight anemia are both highly suggestive of celiac.

Do keep eating gluten until after your biopsy because you can start healing as soon as you withdraw gluten, and affect the accuracy of the test. As soon as you have had the testing done you can start eating gluten free and hopefully start feeling better. Report back to us on how your results turn out and feel free to fire away with any questions you have.

I am really confused because I had my endoscopy this morning and the gi doctor said my small intestines looked normal. He took 4 biopsies but told me He could tell by looking I didn't have celiac disease and the biopsies are not going to be back for up to 10 days.. He basically just said to eat gluten free or it will turn into celiacs disease.. Why is my blood work positive for 2 of the test I I don't have it ? Thanks for any feedback!

Well, Kate, wait until your results come back before you (or he) decide they are negative. The reason they look at them under the microscope is because it is not always visible to the naked eye, especially if you are in early stages. And he reallly should have taken more samples because the distribution of the disease can be very patchy. Most of us here consider that with symptoms, positive blood tests, and good response to the diet, you are celiac regardless of what the biopsy says. I would consider myself celiac with positive DGP alone, but doctors have always pushed for the biopsy as the "gold standard" of diagnosis. This is starting to change, particularly if you add in positive genetic markers for celiac.

Now that your testing is done you can start eating gluten free, and maybe by the time the results are back you will be able to tell him that even if you don't test positive for celiac by biopsy you are most definitely gluten intolerant. Here's to feeling better. :)

The villi are microscopic so a doctor can not tell if those are gone by just looking. Sometimes things will look fine and then the biopsy comes back and it is positive. No matter what the results of the biopsy you do need to get on and stay on the diet. False negatives on both blood and biopsy are all too common. Your blood tests that came back positive are very specific for celiac and you do need the diet. Read as much as you can here and ask any questions you need to ask. You don't need to wait for the results and should go ahead and get yourself gluten free starting today.

t-transglutaminace tTG IgA <1 range is 0-3 negative

That range is interesting. I had this same test done and my result was <3 but the range was listed as 0-5, so my result was still considered negative. :huh:

Different labs use different ranges in their testing, which DOES make it confusing.

Thanks for all the advice I really appreciate it!!! I will definitely update when the biopsy results come back... I thought it was funny that he said I didn't have celiacs disease just by looking... Because the are microscopic! I actually asked for more biopsies but he would do it.. I sure wish that they listened more to their patients! Oh well he told me to go gluten free for 3 months and see how I feel... So I have started today

  • 2 weeks later...

Just wanted to let you all know that the biopsies came back and were normal.. He just said that because of my family history of celiac disease and my positive bloodwork that I should remain gluten free or I could develop damage later on in life. I have been gluten free almost two weeks and feel so much better already!!! He said if I wanted I could have my rash biopsied to see if it is DH.. but really I feel tired of all this medical stuff and just want to move on and stop going to the doctor so much! Thanks for your advice along the way! :)

      results from 13 day gluten challenge - does this mean I can't have celiac?

      By knitty kitty · Posted

      @catnapt, Wheat germ has very little gluten in it.  Gluten is  the carbohydrate storage protein, what the flour is made from, the fluffy part.  Just like with beans, there's the baby plant that will germinate  ("germ"-inate) if sprouted, and the bean part is the carbohydrate storage protein.   Wheat germ is the baby plant inside a kernel of wheat, and bran is the protective covering of the kernel.   Little to no gluten there.   Large amounts of lectins are in wheat germ and can cause digestive upsets, but not enough Gluten to provoke antibody production in the small intestines. Luckily you still have time to do a proper gluten challenge (10 grams of gluten per day for a minimum of two weeks) before your next appointment when you can be retested.

      Supplements for those Diagnosed with Celiac Disease

      By knitty kitty · Posted

      Hello, @asaT, I'm curious to know whether you are taking other B vitamins like Thiamine B1 and Niacin B3.  Malabsorption in Celiac disease affects all the water soluble B vitamins and Vitamin C.  Thiamine and Niacin are required to produce energy for all the homocysteine lowering reactions provided by Folate, Cobalamine and Pyridoxine.   Weight gain with a voracious appetite is something I experienced while malnourished.  It's symptomatic of Thiamine B1 deficiency.   Conversely, some people with thiamine deficiency lose their appetite altogether, and suffer from anorexia.  At different periods on my lifelong journey, I suffered this, too.   When the body doesn't have sufficient thiamine to turn food, especially carbohydrates, into energy (for growth and repair), the body rations what little thiamine it has available, and turns the carbs into fat, and stores it mostly in the abdomen.  Consuming a high carbohydrate diet requires additional thiamine to process the carbs into energy.  Simple carbohydrates (sugar, white rice, etc.) don't contain thiamine, so the body easily depletes its stores of Thiamine processing the carbs into fat.  The digestive system communicates with the brain to keep eating in order to consume more thiamine and other nutrients it's not absorbing.   One can have a subclinical thiamine insufficiency for years.  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so the symptoms can wax and wane mysteriously.  Symptoms of Thiamine insufficiency include stunted growth, chronic fatigue, and Gastrointestinal Beriberi (diarrhea, abdominal pain), heart attack, Alzheimer's, stroke, and cancer.   Thiamine improves bone turnover.  Thiamine insufficiency can also affect the thyroid.  The thyroid is important in bone metabolism.  The thyroid also influences hormones, like estrogen and progesterone, and menopause.  Vitamin D, at optimal levels, can act as a hormone and can influence the thyroid, as well as being important to bone health, and regulating the immune system.  Vitamin A is important to bone health, too, and is necessary for intestinal health, as well.   I don't do dairy because I react to Casein, the protein in dairy that resembles gluten and causes a reaction the same as if I'd been exposed to gluten, including high tTg IgA.  I found adding mineral water containing calcium and other minerals helpful in increasing my calcium intake.   Malabsorption of Celiac affects all the vitamins and minerals.  I do hope you'll talk to your doctor and dietician about supplementing all eight B vitamins and the four fat soluble vitamins because they all work together interconnectedly.

      Desperately need a vitamin D supplement. I've reacted to most brands I've tried.

      By Florence Lillian · Posted

      Hi Jane: You may want to try the D3 I now take. I have reactions to fillers and many additives. Sports Research, it is based in the USA and I have had no bad reactions with this brand. The D3 does have coconut oil but it is non GMO, it is Gluten free, Soy free, Soybean free and Safflower oil free.  I have a cupboard full of supplements that did not agree with me -  I just keep trying and have finally settled on Sports Research. I take NAKA Women's Multi full spectrum, and have not felt sick after taking 2 capsules per day -  it is a Canadian company. I buy both from Amazon. I wish you well in your searching, I know how discouraging it all is. Florence.

      results from 13 day gluten challenge - does this mean I can't have celiac?

      By catnapt · Posted

      highly unlikely  NOTHING and I mean NOTHING else has ever caused me these kinds of symptoms I have no problem with dates, they are a large part of my diet In fact, I eat a very high fiber, very high vegetable and bean diet and have for many years now. It's considered a whole foods plant based or plant forward diet (I do now eat some lean ground turkey but not much) I was off dairy for years but recently had to add back plain yogurt to meet calcium needs that I am not allowed to get from supplements (I have not had any problem with the yogurt)   I eat almost no processed foods. I don't eat out. almost everything I eat, I cook myself I am going to keep a food diary but to be honest, I already know that it's wheat products and also barley that are the problem, which is why I gradually stopped eating and buying them. When I was eating them, like back in early 2024, when I was in the middle of moving and ate out (always had bread or toast or rolls or a sub or pizza) I felt terrible but at that time was so busy and exhausted that I never stopped to think it was the food. Once I was in my new place, I continued to have bread from time to time and had such horrible joint pain that I was preparing for 2 total knee replacements as well as one hip! The surgery could not go forward as I was (and still am) actively losing calcium from my bones. That problem has yet to be properly diagnosed and treated   anyway over time I realized that I felt better when I stopped eating bread. Back at least 3 yrs ago I noticed that regular pasta made me sick so I switched to brown rice pasta and even though it costs a lot more, I really like it.   so gradually I just stopped buying and eating foods with gluten. I stopped getting raisin bran when I was constipated because it made me bloated and it didn't help the constipation any more (used to be a sure bet that it would in the past)   I made cookies and brownies using beans and rolled oats and dates and tahini and I LOVE them and have zero issues eating those I eat 1 or more cans of beans per day easily can eat a pound of broccoli - no problem! Brussels sprouts the same thing.   so yeh it's bread and related foods that are clearly the problem  there is zero doubt in my mind

      Insomnia help

      By cristiana · Posted

      Thank you for your post, @nanny marley It is interesting what you say about 'It's OK not to sleep'. Worrying about sleeping only makes it much harder to sleep.  One of my relatives is an insomniac and I am sure that is part of the problem.  Whereas I once had a neighbour who, if she couldn't sleep, would simply get up again, make a cup of tea, read, do a sudoku or some other small task, and then go back to bed when she felt sleepy again.  I can't think it did her any harm - she lived  well into her nineties. Last week I decided to try a Floradix Magnesium supplement which seems to be helping me to sleep better.  It is a liquid magnesium supplement, so easy to take.  It is gluten free (unlike the Floradix iron supplement).  Might be worth a try.
