Blood Tests And Gluten Challenge
0

6 posts in this topic

Hi. I'm new to the forum, but not new to celiac disease. My daughter, now 46 was born with it. I was told I probably had it (by a physician) but never tested until this yr. First test I had been strictly gluten -free for 2 mos. IGA and IGG were negative. So was the endomesial antibody IGA.

So I did a gluten challenge for three weeks. Tested again. Everything negative but Endomesial antibody went up to just enter the positive range, exactly 1:5.

I'm thinking now I should be on gluten a longer time and test again, because the longer I am on a ciet containing gluten, the more digestive distress I am having.

1. Can anyone explain what the higher endomesial antibody test results might indicate? Should I pursue more testing after a longer gluten challenge?

2. What is an ARA test? Should I have had it or did I already under one of the other names?

3. The nurse read my report to me over the phone, at my request, and mentioned a term that included the words tissue transference (not sure I got it right, but the number she gave me on that was 13, whatever that may mean.

I will meet with my dr. and get these things clear, but frankly I don't think she knows that much about celiac disease or the tests.

I'd like to go armed with the right questions to ask! :)

Thanks for sharing iwhatever nformation you can. Elsie

p.s. I've suffered digestive problems all my life, sometimes called colitis and more recently irritable bowel or "food sensitivities." After being treated for non-hodgkins lymphoma two yrs. ago and learning the higher risk for that among Celiac patients I feel I need to get serious about a definite diagnosis to preserve my present health.

Here's a great site for explaining all those acrnyms:

I hope you find an answer soon. It sounds like you would definitely benefit from a gluten-free lifestyle.

Hope this helps!

Karen, thanks. I checked the site and obtained some useful information. Elsie

I think I may be able to help.

I think the test (#3 on your list) is called Tissue transglutamase

Here is a link to a laboratory test information guide for this test:

http://www.lhsc.on.ca/cgibin/view_labtest....mase%20antibody

If this was the test you had and you had a reading of 13 than I think it means you MAY have tested positive for celiac (I'm not a doctor!). It says on the website that a normal reading is less than 10 U/ml. But it also says "Tissue Transglutamase may give persistent mildly elevated results in the absence of disease". Definitely worth looking into! Of coarse check this info with your doctor.

Tissue transglutamase is the blood test that I had and I was told that this blood test is vey specific for celiac disease.

Different labs use a different reference range. For the Tissue Transglutaminase test most labs say under 20 is negative, a few use under 10 as negative. It is the most specific bloodtest for Celiac.

ARA is Anti-Reticulin Antibody. It is as far as I can tell an outdated bloodtest that very few doctors or labs rely on anymore for Celiac testing. It is still included in some celiac panels though. On mine it said I was negative for the screening test for it, so the actual test was never performed.

The fact that your IgA endomysial antibody went up when you went back on gluten is an indication that gluten may be causing your symptoms, but if you want a definative diagnosis you would have to go back on gluten for anywhere from 3-6 months or more to get more accurate test results. Otherwise you could just continue on the gluten free diet and see if it helps. I went back on gluten for two months and it was not long enough to show my doctor the damage she wanted to see to give the diagnosis of Celiac. I opted for Enterolab testing to get my answers. I am very happy with their testing methods and it is certainly an option. You can check them out at http://www.enterolab.com

God bless,

Mariann

ARA can - as far as I've been able to discover - indicate either autoimmune kidney problems as well, but usually celiac. It's actually relatively specific (in theory), but not very sensitive. (Plenty of celiacs won't have it raised.) That, actually, was my only positive test. (I couldn't get any values on the rest, so I don't know if they were borderline.) When I combined that with a positive result when going on the diet - and doing a dietary challenge - I took that as my answer. It is an indirect test though, and definitely not too many doctors run it any more.

    • Today was the big day when I went to the GI and this is the first time I have felt heard and taken care of.  I told him about the two celiac blood tests  (in my first post) normal, he said that often happens, even with people who do have celiac and he needed to see the report and pictures from my endoscope.    I had filled out the appropriate Kaiser paperwork for Sutter to send all my medical records, but they ended up sending a disc with records to me, which Sutter said they could not use.  We also talked about gluten sensitivity v. celiac, and he said a lot of people are sensitive to gluten even if they don't have celiac. He said that my symptoms sound like classic IBS, which can be caused by any number of things.  He asked if I would try the FODMAP diet, which limits certain foods and requires no gluten. He said my symptoms sound like classic IBS, which he said can be caused by any number of things, including gluten sensitivity.  He has asked if I would try the FODMAP diet, which has restricted foods as well as no gluten because most gluten products have wheat in them.  So, since I am planning on going gluten free anyway, and I don't want another endoscope or blood tests if absolutely necessary, I am going to try the FODMAP diet and see what happens. I filled a consent form at the GI office today to have all my records sent to him so he can view the endoscope pathology report and photos.  I have an appointment with a Registered Dietician on September 30, and follow up appointment the GI in 4 months. 
    • gluten-free andee, according to an article on celiac.com  that talks about this subject see this link http://www.celiac.com/articles/24406/1/Celiac-Diease-and-Other-Autoimmune-Diseases-Equals-Low-Inflammatory-Diet/Page1.html Quoting the author "In the author's personal experience, a gluten-free diet has many limitations. The reactivity between alpha gliadin and corn, millet, oats, rice and dairy has been denounced as invalid by gastroenterologists and celiac disease researchers. While at a medical school in Missouri, biopsies did not show improvement in villous atropy until all alpha gliadin sources and corn, millet, rice and oats were removed from the diet."  Note this research is two years old but hilites the problem with non-gluten rice protein that you are having. It is the alpha gliadin sources that it causing the cross reactivity you are experiencing when you eat rice protein's. She says quoting "Celiac disease has gotten the most attention in antibody research, but the current data on cross-reactivity of antibodies is allowing a better understanding of gluten sensitivity. Antigen reactivity to alpha-gliadin can trigger immune attacks on many individuals beyond those with positive DQ 2, DQ 8 and TTG test results. She goes on to say "A low inflammatory diet customized to each person through testing for cross-reactivity or elimination diet protocols is needed to restore a state of health and well-being."  which sounds exactly like what you are doing. If you are still having problems after elminating rice a 30 day elimination of all the alpha gliadin proteins might be in order.  Corn is a common reactivity problem I hear with a gluten allergy from my friends as well as the obvious lactose problems that can be common among celiacs.  But rarely do you hear Rice allergy's brought up in context of a gluten allergy. I am glad you are making progress on finding your triggers. Read the whole article for yourself to see if there are nuggets of truth I did not highlight in my response. I hope this is helpful. Good luck on your journey to health. Posterboy,
    • One other thing - you might be able to tolerate some dairy if it's only the FODMAPs problem. I discovered that many cheese such as cheddar have effectively no lactose. And my wife sometimes makes 24 hour yoghurt, which also has effectively no lactose. Those have been fine for my tummy.
