Hi, i was referred to a gastro specialist two years ago and still no outcome. my symptoms are similar to ibs so i am assuming that is what i have. i recently mentioned about having a blood test for celiac disease as i do notice when i have gluten my symptoms are intensified. i had my results over a month ago and have been trying to get the doctor to go through the results with me. the result number means nothing to me but is outside the normal range on the low end. i just want someone to tell me if i need to worry or not!! does anyone know the celiac disease parameters for immunoglobulin A my result was 0.62 g/L if that helps. Thank you!!

Welcome to the forum, @alj67!

Different labs used different ranges for all these celiac diagnostic tests in order to establish what is low vs. normal vs. high. Without knowing the range parameters used by the lab doing the analysis we cannot shed any light on your question. Do you have any more information? Was that the only test run? It looks like it may have been the test for what we commonly call "total IGA" which is a measure of IGA deficiency/sufficiency. If total IGA is low, i.e., deficient, the individual IGA antibody tests used to diagnose celiac disease may give falsely negative results, or at least lower scores than they ought otherwise. In your reply, please post all test info you have exactly as you have it.

Hi @trents

the results show 0.87-4.12g/L as the normal range. they also ran a bone and thyroid profile both of which were fine. i have previously had an ultrasound where nothing was seen and have done a breath test which came back as ‘High methane production, possible IMO’ 

Thanks :)

That is a test for total IgA, it is not a test for the IgAs related to celiac disease. As Trents said, since it is a bit low, the celiac IgA tests may give falsely low results.

I think is is significant that you say your symptoms are worse after consuming gluten. Your next logical step would be to request a celiac panel including IGA and, since your total IGA is deficient, IGG antibody tests:

TTG-IGA

DGP-IGA

TTG-IGG

DGP-IGG

You would need to be eat a significant amount of gluten daily, the equivalent of at least 4-6 slices of wheat bread or 10g daily, for several weeks before the blood draw. If you are withholding gluten from your diet the testing will be invalidated. You could also have (Non Celiac Gluten Sensitivity) instead of celiac disease. NCGS shares many of the same symptoms of celiac disease but does not damage the lining of the small bowel as does celiac disease. There is no test for it. It is 10x more common than celiac disease. Some experts feel it can be a precursor to the development of celiac disease. Eliminating gluten from your life is the antidote for both. An NCGS diagnosis depends on first ruling out celiac disease through testing.

Here is an article outlining the various tests that can be used to diagnose celiac disease:

If your celiac testing proves to be negative, you need to look at NCGS (Non Celiac Gluten Sensitivity). NCGS shares many of the same symptoms of celiac disease but does not damage the lining of the small bowel as does celiac disease. There is no test for it. A diagnosis for NCGS depends on first ruling out celiac disease. It is 10x more common than celiac disease. Some experts feel it can be a precursor to the development of celiac disease. Eliminating gluten from your life is the antidote for both.

Welcome to the forum, @alj67,

IMO and SIBO are common in Celiac Disease.  Cutting out carbohydrates and following a Paleo diet, like the Autoimmune Protocol Diet, can rid the digestive tract of these bacteria.  

Ask for a DNA test to look for the most common genes for Celiac Disease.

      New (possible) celiac diagnosis

      By trents · Posted

      Welcome to the forum, @Judy M! Yes, he definitely needs to continue eating gluten until the day of the endoscopy. Not sure why the GI doc advised otherwise but it was a bum steer.  Celiac disease has a genetic component but also an "epigenetic" component. Let me explain. There are two main genes that have been identified as providing the "potential" to develop "active" celiac disease. We know them as HLA-DQ 2.5 (aka, HLA-DQ 2) and HLA-DQ8. Without one or both of these genes it is highly unlikely that a person will develop celiac disease at some point in their life. About 40% of the general population carry one or both of these two genes but only about 1% of the population develops active celiac disease. Thus, possessing the genetic potential for celiac disease is far less than deterministic. Most who have the potential never develop the disease. In order for the potential to develop celiac disease to turn into active celiac disease, some triggering stress event or events must "turn on" the latent genes. This triggering stress event can be a viral infection, some other medical event, or even prolonged psychological/emotional trauma. This part of the equation is difficult to quantify but this is the epigenetic dimension of the disease. Epigenetics has to do with the influence that environmental factors and things not coded into the DNA itself have to do in "turning on" susceptible genes. And this is why celiac disease can develop at any stage of life. Celiac disease is an autoimmune condition (not a food allergy) that causes inflammation in the lining of the small bowel. The ingestion of gluten causes the body to attack the cells of this lining which, over time, damages and destroys them, impairing the body's ability to absorb nutrients since this is the part of the intestinal track responsible for nutrient absorption and also causing numerous other food sensitivities such as dairy/lactose intolerance. There is another gluten-related disorder known as NCGS (Non Celiac Gluten Sensitivity or just, "gluten sensitivity") that is not autoimmune in nature and which does not damage the small bowel lining. However, NCGS shares many of the same symptoms with celiac disease such as gas, bloating, and diarrhea. It is also much more common than celiac disease. There is no test for NCGS so, because they share common symptoms, celiac disease must first be ruled out through formal testing for celiac disease. This is where your husband is right now. It should also be said that some experts believe NCGS can transition into celiac disease. I hope this helps.

      New (possible) celiac diagnosis

      By Judy M · Posted

      My husband has had lactose intolerance for his entire life (he's 68 yo).  So, he's used to gastro issues. But for the past year he's been experiencing bouts of diarrhea that last for hours.  He finally went to his gastroenterologist ... several blood tests ruled out other maladies, but his celiac results are suspect.  He is scheduled for an endoscopy and colonoscopy in 2 weeks.  He was told to eat "gluten free" until the tests!!!  I, and he know nothing about this "diet" much less how to navigate his in daily life!! The more I read, the more my head is spinning.  So I guess I have 2 questions.  First, I read on this website that prior to testing, eat gluten so as not to compromise the testing!  Is that true? His primary care doctor told him to eat gluten free prior to testing!  I'm so confused.  Second, I read that celiac disease is genetic or caused by other ways such as surgery.  No family history but Gall bladder removal 7 years ago, maybe?  But how in God's name does something like this crop up and now is so awful he can't go a day without worrying.  He still works in Manhattan and considers himself lucky if he gets there without incident!  Advice from those who know would be appreciated!!!!!!!!!!!!

      You've done an excellent job of meticulously tracking the rash's unpredictable behavior, from its symmetrical spread and stubborn scabbing to the potential triggers you've identified, like the asthma medication and dietary changes. It's particularly telling that the rash seems to flare with wheat consumption, even though your initial blood test was negative—as you've noted, being off wheat before a test can sometimes lead to a false negative, and your description of the other symptoms—joint pain, brain fog, stomach issues—is very compelling. The symmetry of the rash is a crucial detail that often points toward an internal cause, such as an autoimmune response or a systemic reaction, rather than just an external irritant like a plant or mites. I hope your doctor tomorrow takes the time to listen carefully to all of this evidence you've gathered and works with you to find some real answers and effective relief. Don't be discouraged if the rash fluctuates; your detailed history is the most valuable tool you have for getting an accurate diagnosis.

      Gluten free beer ?

      By Scott Adams · Posted

      In this case the beer is excellent, but for those who are super sensitive it is likely better to go the full gluten-free beer route. Lakefront Brewery (another sponsor!) has good gluten-free beer made without any gluten ingredients.

      Welcome to the forum, @catsrlife! Celiac disease can be diagnosed without committing to a full-blown "gluten challenge" if you get a skin biopsy done during an active outbreak of dermatitis herpetiformis, assuming that is what is causing the rash. There is no other known cause for dermatitis herpetiformis so it is definitive for celiac disease. You would need to find a dermatologist who is familiar with doing the biopsy correctly, however. The samples need to be taken next to the pustules, not on them . . . a mistake many dermatologists make when biopsying for dermatitis herpetiformis.
