Correct testing for celiac disease

I have most of the symptoms of  celiac disease and DH and have had negative results for IgG and IgA.  I am worried that the negative results may be due to  IgA deficiency.   My doctor has ordered protein electophotesis but this does does not seem right to me.  Advice regarding the correct tests would be much appreciated.

Hi, just a short reply:

- Gliadin IgA, Gliadin IgG, TTG IgA, TTG IgG, Endomysium IgA, Endomysium IgG + Total IgA (= serum level of total immunoglobulin A)

- 10 percent of celiacs are seronegative, i.e. negative blood test + positive intestinal biopsy

- some people are non-celiac gluten sensitive (NCGS) - no tests available

- DH is diagnosed via a skin biopsy - a dermatologist can diagnose it; only celiacs have DH

Hope this is a bit helpful :)

Thank you for the information.  I am having an endoscopy in December as I want a definitive diagnosis and because of my age and health issues I cannot afford to muck around.  My GP who is usually very good seems to be ignorant regarding Celiac Disease, which I find a bit bizarre considering 1 in 70 Aussies are sufferers.   The assumption of GPs tends to be " It is IBS because Celiac is so rare we don't test for it".   Maybe why 4 out of 5 people with Celiac are misdiagnosed or undiagnosed.

      You can sell it better if the whole family does gluten free.  If he does have Celiac Diease, it is genetic so either you, your spouse, or both have a 40% chance of also having Celiac.  There are over 200 non classic symptoms also caused by celiac disease not often considered by doctors. Joint pain, muscle pain, muscle cramps, osteoporosis, and allergies for starters.

      On the cusp of facing a new life of managing a life with Celiac Disease

      Hello @MHavoc, thank you for your question and welcome to the clinic. First, has the contstipation abated with the GFD? If your are pursuing further diagnostics you must continue to eat gluten. Each lab has their own reference range for their test, but they indicate an H for high.  Typically anything above 11 is considered positive. Mild chronic inflammation (gastritis) can interfere with intrinsic factor for B12 leading to low B12 causing low MCHC (anemia). So what is causing your gastritis?  A high tTG IgA level generally indicates potential gastrointestinal problems most commonly associated with celiac disease.  Although the biopsy is the Gold Standard for diagnosis, not finding damage in the biopsy does not rule out Celiac Disease. It means they did not find damage where they looked.  The small intestine is over 20 feet long. Many here have been blood positive and biopsy negative, it just delays the diagnosis until you have enough damage to find and fit their diagnostic profile. The Ttg-iga is not only sensitive (90%) but highly specific (98%) and won’t show positive until the damage is severe.  It is estimated that 40% of first degree relatives of diagnosed Celiacs have undiagnosed Celiac Disease, so your sister is a big risk factor in whether you have it. Are You Confused About Your Celiac Disease Lab Results?  This article explains it better and is quite readable. Celiac Disease can cause deficient vitamin D.  Low vitamin D compromises the immune system.  Any other symptoms? liver enzymes?  Recent cold or flue? Celiac Disease and the malabsorption it causes through vitamin and mineral deficiencies can elicit symptoms not usually associated with Celiac Disease. Case in point maybe your gastritis and anemia.

      As with most of the people that come here, I have questions and need perspective/info from this wonderful community.  Some background, started having severe constipation that would not abate even with softners (not really fun to talk about), so I was able to finally get in to see my primary and she scheduled some blood work.  One of things she wanted to test for is Celiac Disease due to my sister having celiac disease since a young child. Here are my test results: MCHC = 31.4 so considered slightly low TISSUE TRANSGLUTAMINASE AB, IGA = 78.8 H So with that result, I was scheduled for an endoscope for confirmation of celiac disease, but I am very confused with the results: Diagnosis 1. Duodenum, biopsy: -No pathologic alteration. 2. Stomach, biopsy: -Mild chronic inflammation with reactive epithelial change -H. pylori not identified on immunostained section. -No intestinal metaplasia or dysplasia I am now scheduled to meet with a GI Specialist from the Celiac team, but that won't be until after the New Year.  I would appreciate thoughts about the biopsy report to understand whether it confirms the celiac disease as was indicated by the blood test results. I have been gluten free for two weeks and it is a very difficult adjustment for me as an older 50+ person.

      Anyone else have intermittent left ear ringing and outer right ear pain? Both seem to happen in the evenings.

      If your son eventually becomes very symptomatic, that in itself will help keep him on the diet.  I had a friend who was diagnosed roughly the same time as me and she used to tell me a lot that she could get away with eating certain gluten containing foods.  (Not a good thing to do, but she did all the same).  In time she was unable to tolerate them anymore,  and is now very strict with her diet.   The football situation with the candy:   here in the UK at least, a lot of mainstream chocolate bars and sweets don't actually contain gluten (Bounty Bar, Snickers, Cadbury's Whirl, Crunchie etc) and you may find that that is the case where you live.
