I have gone to a lot of doctors and on my own have discovered excluding gluten from my diet has radically changed all of Celiac symptoms. I've read that I would have to go back on gluten in order to take a lab test. That's crazy. I wouldn't do that! I liken that to telling a child it's okay to play on the freeway. It's not my fault the medical community doesn't have a good test. How come they are able to test hair for drugs, etc., but can't do something that simple for gluten?

Okay, here is my main question. I understand that DNA testing does not confirm Celiac only "rules it out." That's okay with me. I watched my father go through (never diagnosed) ALL of my same symptoms and then die of colon cancer. :( Incredibly sad. I am 60 years old and JUST discovered on my own what has been going on in my body forever.

I see so many chats that unable to get positive blood tests or endoscopy findings.:( I understand this can happen no matter what level of gluten protein is in my blood....pardon the expression, but it's a crap shoot.

I'd like to know how to get DNA testing...is it expensive? Thank you.

I had my DNA testing done through Enterolab. I'd suggest going to their website, www.enterolab.com, and checking into it to see if it's what you're intersted in. You can also have stool testing done there which is another option.

The gene testing through Enterolab costs $149.

Good luck! And by the way, I'm glad to hear that you're feeling better on the gluten-free diet. Me, too! :)

My GI ordered gene testing through a regular lab for me because I was in the same situation as you- my initial bloodwork was negative, but I wasn't about to go back on gluten for an endoscopy. It turns out I do have the common allele for celiac, and that combined with my symptoms, he says, is enough for a diagnosis.

The only problem is that insurance is refusing to cover it, and it's a $500+ test. But we're fighting the charge, and the GI is helping, so it might work out. Just double check on that...stupid HMOs...

I had my son tested through Enterolab as well after his bloodwork and biopsies came back negative. Turns out that he has both celiac genes, that in combination with his great dietary response is enough proof to me.

I actually got gene testing done on the "back end". I had been on the diet for over a year based on positive biopsy. (There was no need for a blood test because I was so malnourished the doctor went straight to the scope). Anyway in order to see how I was progressing I had the Celiac panel done and while I was at it requested the gene test for myself and my mother. She came from a large family and many of her brothers and sisters are still alive. Both of us had the DQ2 gene. My Celiac panel was "perfect" as one might expect after being gluten-free for over a year. At first her insurance did not want to pay but we persisted saying it was in fact "preventive medicine" in that knowing the gene exists means if symptoms did start the diet could be a first option. The insurance company paid the bill. It can be quite expensive.

It is my opinion that if someone suspects Celiac then the most logical approach would be the diet first or gene testing and the diet to see if you are on the right track. Either way you could hold down the cost. If you respond positively to the diet you can either get on with your life or decide at some point to attempt more testing but as you probably already know what's the point if you will ultimately end up on the diet for good anyway. Hope this makes sense and good luck.

Genetic testing does not and cannot rule out Celiac Disease. Celiac Disease isn't exclusive to the DQ2 and DQ8 genes. Two percent of diagnosed Celiacs do not have DQ2 or DQ8. I have DQ1 and DQ3, and I am a diagnosed Celiac. So even if your DNA tests comes out negative for DQ2 or DQ8, you can still have Celiac Disease. Just something to keep in mind,

Brian you took the words right out of my mouth. The genetic research into celiac is in it's infancy, not all the genes are recognized. If I had relied on blood tests and gene tests for diagnosis I would be dead by now. I didn't have my genes tested until I had been gluten-free for almost 4 years. I did it because my DD was gene tested and came back negative for DQ2 and DQ8 and the doctor told her there was absolutely no way she could be celiac as she didn't have the genes and that her previous biopsy derived diagnosis was false. Yea right. There is no doubt that I had full blown celiac and guess what I don't have the recognized genes. My gene in the US is recognized as a gene for rheumatiod arthritis, if I hadn't already been gluten-free I would still be existing on arthritis meds instead of being in remission from my arthritis and my multitude of other autoimmune mediated diseases.

      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...
