DNA Test?

3 posts in this topic

Hello my name is Kristy and ive been sick since april. Stomach pains, Diarrhea, and Fatigue have been the main problems. I went from thinking i had a virus to parasites with any tests coming back negative and normal. Ive been limited in testing and doctor visits as im now unemployed and without health insurance. Just over a week ago my mother told me i should check into Gluten intolerance so i did and ive been on the diet since. I think its helped but im not sure and its hard to do when i dont KNOW if its my problem. I learned that my grandmother has always had stomach issues but never found the source, perhaps she had celiac and perhaps i have it now too? So my main question here is should i get the DNA test to see if i have the celiac genes and how much does this kind of test cost?

The DNA test is not a diagnosis. For one thing many carry the genes and not all will have celiac. In addition gene testing is a relatively new science and many companies only test for 2 out of the 9 known celiac associated genes.

IMHO you would be better off getting a celiac panel done through your doctor. If you have been seeing one for these issues they may be able to order the test and you could pick up or have the lab slip mailed to you without having to pay for an office visit. You do need to keep eating gluten until all testing is finished. There is also about a 20% risk of a false negative with the blood tests and biopsies so if you do go that route do go gluten free after the tests are done. Your body will give you the answer.

There are people here on the board who are 'self diagnosed' as you really don't need a doctors permission to be gluten free. However if you do go gluten free any tests you want done later will be negative without a gluten challenge of about 3 months. The challenge will make most of us very sick if we need to be gluten free as the body will really not like having those antibodies reactivated.

You could also go the Enterolab route, they do gene testing for all the 9 genes but IMHO the more valuable part of the testing is the stool test for antibodies. You can check out their web site for prices and also check out some of the posts here about Enterolab to make an informed decision on whether you want to do their tests or not. Some do not like Enterolab because they haven't had their testing procedures 'peer reviewed' but others consider them to be a valuable part of the diagnosis.

Read as much as you can here as the diet does involve more than just food. Ask any questions you need to.

Just to emphasize what RWG said, there are no Celiac genes that have been identified. A DNA test is interesting, but not informative.

If you think gluten is your issue, consider either trying the diet, or exploring other testing.

    • Has your derm ever done a dh biopsy? BTW, it's not taken ON a lesion, it's taken on clear skin adjacent to a fresh lesion. I bet your derm doesn't know that. I bet if you ask for a dh biopsy he will take it right on top of a lesion. Ditch him & get a derm who knows about celiac & dh & how to properly take a biopsy for it. The antibodies can stay under the skin for years. The derm is wrong.  Please describe how the rash acts & what it feels like.
    • Yes, there are other grains that have gluten but they don't have the TYPE of gluten that affects celiacs. Celaics can not have the gluten in wheat, barley, & rye. Corn has gluten but it is not the kind of gluten we react to. I actually use corn gluten in my garden as it prevents weed seeds from sprouting. LOL! Hey, it works great! Read these: Gluten is the name for the protein in grains. All grains contain protein that is theoretically gluten but people with celiac disease and most other gluten allergies only react to the form of gluten found in wheat (including spelt, kamut, triticale and all varieties of wheat), barley, and rye. From:   I've run across another gluten urban legend that needs to be dispelled: the idea that people with celiac disease and non-celiac gluten sensitivity actually react to gluten in all grains, not just wheat, barley, rye and sometimes oats. This just isn't true, despite what you might have heard or read. People who react to the gluten protein found in wheat, barley and rye don't automatically need to avoid rice, corn, millet, sorghum and other grains. From:   There are some unsavory sites out there in internet land that will tell you celiacs cross react to all grains. They generally have something to sell, a book, a video, some vitamins or other things. They use scare tactics to sell what they are selling. These claims simply are not true. If they were, then all the people on this site who have gotten well while not eating wheat, barley & rye but continuing to eat rice, quinoa, corn & so forth would not have gotten well; they would be dead by now & there would be no "old timers" on this site because they would have eventually died from eating grains other than wheat, barley & rye. Celiacs can develop sensitivities to other foods, even foods like cabbage or lettuce or potatoes or even rice or maybe only brown rice but that does not mean they are reacting b/c of gluten in those things. You may be doing great since eliminating rice from your diet and that is wonderful that you figured out that it affects you but that does not mean the rice contains the kind of protein that celiacs can not tolerate.  
    • So, I've had a skin condition for years which looks like DH but blood tests for it come back normal.  High doses of steroids or of immuno-suppressants work well to clear my skin, but as soon as they are reduced the inflammation returns.  I tried a gluten free diet for a month, during which my skin seemed to set on fire even more.  My dermatologist says if my problem was DH then I would have had a positive result from going gluten free for four weeks, although information on the internet suggests it takes at least 6 months.  Does anyone have some experience of something like this?  Do I believe my dermatologist or the internet???
    • Working a modifying a recipe to be both Vegan and Grain free. I am a bit low on funds right now and can not test it. Feed back is welcome and if you do it perhaps  get me a grams breakdown for duplication. 1 cup almond flour
      ½ cup unsweetened shredded coconut
      1 teaspoons cinnamon
      1 teaspoons apple pie spice
      1 teaspoon baking soda
      ½ teaspoon salt
      ¾ cup unsweetened applesauce
      ½ cup almond butter
      ½ cup Maple/Agave
      2 Tablespoons soft coconut oil
      2 Tablespoons Ground Flax Seed combined with 5 table spoons water whisked and set aside
      1 medium apple, diced small (about 1¼ cups)
      1 cup chopped pecans
      ¼ cup flax seeds

      Preheat oven to 350° F and grease a 9 x 13 inch baking pan.
      In a mixing bowl, whisk together the almond flour, coconut, cinnamon, baking soda, and salt.
      Add the applesauce, almond butter, honey, coconut oil, and ground flax mixture. Beat with a mixer until everything is incorporated.
      Stir in the diced apple, pecans, and flax seeds.
      Spread the batter in the prepared pan and bake for 25min
