Test Results Pointing To Early Stage Celiac?

Just got the results of my tests. This reeks of very recent development of celiac disease to me. Any ideas? With the marginally positive IgA and somewhat high negative IgG, also note the borderline negative transglutiminas IgA at 3. Of other note all bloodwork at my general physician in Decmember was normal including RBC, hemoglobin, iron, calcium, and thyroid. I have had IBS symptoms on and off for 15 years or more, have not really noticed any glaring symptoms change in recent times. I did have a period in December of 5-7 days of pretty nasty gas and bloating but no diarrhea. In the last 3-4 days the same pattern resurfaced and now appears to once again be improving. Is this cyclical symptom pattern somewhat common in celiac? I was eating some pretty horriblly glutened foods for Xmas and the entire last 6 weeks since the first flareup and no symptoms whatsoever til the same thing came back last week.

Deamidated Gladin IgA - 20

Weak positive 20-30

Demidated Gladin IgG - 15

Negative 0-19

Transglutiminase IgA - 3

Negative 0-3

Transglutiminase IgG - <2

Negative 0-5

Endomysial Antibody IgA - 174

Normal range 91-414

C-Reactive Protein - 0.7

Normal range 0.0-4.9

This reminds me of my blood work, only my DGP IgG is weakly pos at 24. Does your doctor have any input about the weak pos. DGP IgA? There is a poster here that has great info with the screen name Mushroom who forwarded me an article by Dr. Ford explaining deamidated gliadin peptide tests and they seem to be pretty specific for celiac disease.

No, didn't have the follow up yet so no specific one on one conversation. I've come across some research that shows surprisingly these are not exactly the breakdowns you want to see as a potential celiac. Although most argue a non positive EMA that falls decently within normal range means less intestinal damage and the likelihood you've caught the condition much earlier on, some think the lesser fight put up within the intestines and hence lower EMA # increases the risk of malignancies to develop. I was told by a family member who is a general practitione to wait 90-120 days and do the blood test again and see if the #s increase any, she has advised me not to go through the invasive endoscopy procedure just yet based on those #s and my otherwise normal supplementary blood work.

Blood tests are often difficult to interpret, with the one weak positive it makes it even more difficult. That is what sucks about Celiac, often the diagnosis is up in the air and not so clear cut.

I am not sure what you are speaking about with the Endomysial, the range you provided makes me think that you have mistaken that for your total serum IgA? There is no "falling decently in range" endomysial, and endomysial can't be "below range". It is listed as a titre, 1:5 and below is considered negative, above will be reported as positive.

The theory of a low EMA, which again does not exist, provides a greater increase of malignancy does not make sense. If you have a positive EMA it is showing damage to the intestines, the higher the titre the higher the damage, the higher the damage the greater the risk increase of malignancy. A negative EMA is a good thing.

The advice of retesting in three months sounds great, keep on top of it and make note of any symptom changes. If it provides you with any comfort I had a weak positive deamidated IgG of 11 (>10) and TTG 16 (>10) after a bout of Salmonella. I got biopsied months later in which my intestines were perfectly healthy and the next blood test 4 months after the previous was negative. Good luck!

I expressed my desires about the blood test and was sort of rebuffed. Doc claims that the borderline IgA and negative EMA in no way is a guarantee the disease is recent at all, said someone with the disease for 18 years can have a 21 IgA and negative EMA while someone only having it for 18 months can have a 40 IgA and 600 EMA...no guarantee that the #s suggest duration. I countered with the normal calcium/vitamin/iron levels on the generic blood workup and he said THAT could hold some water about this being recent but still said there are plenty of patients with the illness for decades who do not suffer the iron or vitamin deficiencies.

I also agree that doing follow up blood work would be good. I have also wanted to see what my DGP would be. There is one study I found online that claims that the dgp can sometimes be falsely pos. And fall without taking gluten out of the diet. This is where the confusion sets in because many studies also show that dgp is extremely sensitive and accurate in detection of celiac. You may want to experiment with a gluten-free diet just to see if you begin to notice any difference. I have been gluten-free for about a week now faithfully and the change is astounding. I hope I continue feeling better. I really am curious as to what next step you will take and please update us! :)

    • I have read the newbie 101 and have been careful about reading labels. I'm the only one that's gluten free in my household, so they could be contaminating me. I was eating gluten for 6 weeks after my blood test because it took that long to get an official diagnosis and my GP told me to still be eating it for the tests to be accurate. It was probably too soon to retest, but the test was accidentally ordered by the lab. I have been having an increase in joint pain over the last couple months and my rheumatologist ordered lab work. The lab saw the celiac panel had been ordered, but didn't see results so they added it on because they thought it still needed done.  My gut issues are starting to get better, but I'm thinking the joint pain might have been from the celiacs because all of the rheumatoid tests came back normal for the first time in twenty years.
    • Hi and Welcome to the Forum.  I am glad that you are here! As with a lot of things in life, try not to compare yourself to other people. You are trying to be the best version of yourself - not Jill, Annie, or Maya.  People make a lot of foolish decisions in the world and it does not mean that you should do it too.  Also, many people are gluten free for a lot of reasons that aren't celiac. One of my best friends has gluten sensitivity but not celiac.  He eats a lot of food that I won't touch due to possible cross contamination which he doesn't worry about too much.  Be true to yourself and keep your self healthy.  It is so hard, but it's better than getting sick! I hate not being able to partake in yummy food at parties, but I have learned what junk food I can eat.  I will make sure to buy some tortilla chips or Fritos for picnics.  I freeze gluten-free cupcakes to eat when we celebrate birthday parties (I can just take one out of the freezer and go).  I make sure to take a dish to share to potlucks.  I ask permission at restaurants and parties to bring my own food - no one has ever said no, and when there is a time to celebrate, I splurge on something I really like.  Fortunately, there are a lot of gluten-free foods that I really like. Do i miss pizza and really good burger? YES! And sometimes, I still feel awkward, but life is so much more than food.
    • Holy cow! You people are all angels! I have been suffering unbearably with these hot, itchy, and painful bumps on my scalp for a year now. Two doctors had no idea what it was, so I was sent to see a "dermatologist." To my utter shock, he told me I WAS DIRTY! HE TOLD ME TO WASH MY HAIR EVERY DAY with a shampoo called Nizoral, that it would take the itch away. He also prescribed a Vaseline based salve with a steroid in it. Guess what? It did nothing nor did the shampoo, and the more I washed my hair, the worse it gets. It's like torture, and I just can't stop scratching holes into my scalp. Then they scab over, then itch again. I was almost ready to shave my head, until I found this forum. I knew nothing about celiac disease, sensitivity to gluten... I knew nothing. Just so happened that my daughter found a paper talking about celiac during her visit to her GI yesterday. She brought it home for me, and demanded that I read it!  WHAM- a light come on, and I said to her... That IS what I have. I am going to my GP tomorrow to demand that I be tested for ciliac. I am rather terrified, as I am already a type 1 diabetic and have been on insulin for 52 years! I was blaming my diabetes the whole time. I have had a lower left leg amputation, and the last thing I need is to start getting this ungodly rash on my stump!!! Thank you everyone for all of the useful information you have provided in this blog. Maybe I'm not going to die after all! 😉
    • The University of Chicago recommends re-testing 3 to six months after going gluten free and then annually.  Most GIs wisely wait because although you can theoretically heal that fast, it takes TIME to master the gluten free diet.  It can take up to a year or longer for antibodies to come down.  As someone who has more than one autoimmune issue like myself (and only a DGP IgA that has ever been elevated), I think that impacts healing  and how quickly antibodies come down.   My recent endoscopy (5 years post diagnosis) revealed a healed small intestine, yet my DGP IgA was still at 80 (which was over 200 last April when I was somehow exposed to gluten).   Hang in there!  Wait six more months to get retested.  Look for other signs of healing (like anemia resolving, improve gut issues).  
    • Sounds great, one of my dreams is to open a grain free/gluten free food truck.......stone and mortar places would not do well here, but a mobile one able to cater....LOL dream I know, fundraiser has flopped and been running for a year. Hell I had the quotes up, the whole sale contracts setup, the business model and plan. I even tried to get loans, and business partners.....all flopped.
