Reference Ranges

Why are the reference ranges different for different labs? My son has very infrequent bowel movements (but he's not constipated and does not experience stomach pain; just gets distended and IRRITABLE!). He eats a very healthy diet, lots of fresh vegetables, fruits, and water. I would like to rip the pediatrician's head off for always telling me all kids' gi problems are related to their diet. Anyway, deamidated gliadin igg was 7 and deamidated iga was 2. According to quest labs, this is negative. I found other labs online (pediatric children's hospital in minnesota) that says 7-10 is equivical. His HLADQ2 was positive and nothing else in bloodwork is remarkable for celiac. One family member (deceased) who claims she had celiac sprue. Our lives are already flipped upside down because our other son has severe food allergies/eosinopohilic disease so yes, it is a big deal to pull wheat if it's not the problem. Can someone please help us. How long would we have to be gluten free to notice a difference in bowel habbits and behavior issues?

I think each lab sets their own reference ranges. I had the older celiac panel through Quest and my daughter in Denver had the newer DGP through LabCorp...the reference ranges are different but we were both positive.

Did you pick up a copy of your son's lab results? That should show you the reference ranges your lab used.

I'm sorry your son is having so many problems. Are you going to have any further testing done? If not, you can go gluten-free. I don't know the answer to your last question...I think it varies with the individual but hopefully children heal faster than adults.

My heart goes out to you as a mom, having such awful things happening to your son. I find it really interesting... what you talked about with both of your boys, as I am also DQ2 positve (DQ2.5 specifically) and I also have elevated eosinophil levels that they are still trying to figure out, along with testing for celiac disease. Don't have my results back yet, as I just had my biopsy yesterday, but it makes me wonder if those things are all tied together. (my inquisitive nature again... I should have been a medical research scientist...lol)

Anyway, about your question.... I noticed you referenced a medical lab in Minnesota and wondered if you happen to have access to Mayo Clinic if you life in MN. The reason I ask is that they do have a celiac department headed by Joseph A. Murry (practicing GI and head of the Celiac research there) and I know he has a collegue who is a pediatrician very knowledgable about Celiac. If you can get in to see them, your questions would likely be answered. Otherwise, as Sylvia said, most labs have their own reference ranges, so to compare results from a different lab would be skewed. Good luck with your search for answers. Hope your son feels better soon!

Eosinophils cirrculating in the blood are not always elevated in eosinophilic gastrointestinal disease. Both of my children have normal lab work. My youngest son presented with chest pain, vomiting, and reflux like symptoms. Biopsies of his esophagus and some other areas showed the eosinophils in the tissue. I do not know if there is a link but the report from the villi biopsy looks identical to that of a celiac. I do not know how they make a distinction (or if they do) between the two.

      Finally got in to doctor to get my referral and I lucked out and got into Gastro the same day - question about different transglutaminase results

      By cameo674 · Posted

      The GI doc messaged me this afternoon that she believes that the new blood work added to the old is definitely  looking like a celiac diagnosis is in my future.  She wants to me to call into scheduling each Monday to see if I can get my August 29th appointment moved up due to cancellations.  I have never had a doctor recommend that.  She also said there were additional labs that she requested still out that have not come back yet; so, they may have been missed drawing those since the functional health doctor has a whole slew of labs that I am suppose to be waiting until August 27th to do. I am still waiting to hear on whether or not she will allow me to do pill prep versus the typical...

      Latent celiac, need to go gluten free, advice on kitchen "reset?"

      By Alibu · Posted

      Well, I've made if from the pre-diagnosis forum to here!  I've been diagnosed with "latent" or "potential" celiac and my doctor has suggested me to go gluten-free before my appointment with him in October (first available, LOL).  My ttg-iga was 152, my EMA was positive, I have the gene, but my biopsy was negative (and he took 12 samples), so it makes sense to go gluten free to see if I improve. I know the basics - I can find lists of things to avoid, I know about hidden dangers, etc. all of that.  Where I'm struggling is just STARTING.  I need to go shopping and stock up on some staples.  My goal is to not try to find gluten-free alternatives, but to focus on naturally gluten-free foods like...

      By Scott Adams · Posted

      It’s great that you were finally able to see a gastroenterologist—and even luckier to get in the same day as your referral! It sounds like your GI is taking a very thorough approach, which is reassuring given your complex symptoms and history. The confusion around your different tissue transglutaminase (tTG) antibody results is understandable. The variation between your December and June labs may be due to multiple factors, including differences in the lab performing the test (Quest vs. Mayo Clinic), the specific assay used, and the amount of gluten you had been consuming before each test. Antibody levels can drop significantly when gluten is reduced or eliminated from the...

      Gluten free thyroid medications

      By Scott Adams · Posted

      I don't believe that site is updated regularly, and it may be unreliable.  You can search this site for prescriptions medications, but will need to know the manufacturer/maker if there is more than one, especially if you use a generic version of the medication: To see the ingredients you will need to click on the correct version of the medication and maker in the results, then scroll down to "Ingredients and Appearance" and click it, and then look at "Inactive Ingredients," as any gluten ingredients would likely appear there, rather than in the Active Ingredients area. https://dailymed.nlm.nih.gov/dailymed/

      Gluten free thyroid medications

      By KimMS · Posted

      Hello! I did a brief search on this and couldn't find recent posts, but feel free to direct me to something if I missed it! I have had a difficult time confirming which thyroid medications (specifically generic forms of Levothyroxine) are gluten-free and safe for celiacs. I am pretty confident the generic manufacturer Mylan is safe, and I have been taking this for almost two years. Recently (I think b/c of a recall), Mylan has not been available at my local pharmacies. The list I typically use for gluten-free drugs (http://glutenfreedrugs.com/newlist.htm) does not list any of the other manufacturers offered by pharmacies in my area (Accord and Macleod). When I do a search, sites tend to say these...
