Genetic Testing For Celiac - Questions

Hello, I have been gluten-free since 6/5 and 99% Casein free as well since then. I had an endoscopy done on 6/5 to see why I had been nauseous for almost 2 years and I asked the GI doc to do a biposy. He did 1, and said it was negative for Celiac (but note, only one sample was taken). 6 weeks later I went to be tested for food allergies and the doc did a Celiac blood test which also came back negative. HOWEVER, I have definitely seen a huge health improvement from going gluten-free and so I plan to stick with it. Now, my questions lie in the genetic testing that can be done for Celiac:

1) how accurate are these tests? I know that they can biopsy spots w/o damaged villi, and you could still have Celiac....and I know blood tests are not always accurate (esp when gluten-free for awhile). So what is the accuracy of the genetic testing?

2) is there a 'better' genetic test lab than another?

3) I am assuming a genetic marker will show up regardless of how long you have been gluten-free?

4) any other thoughts to share with regard to the above?

The reason I am concerned is mostly for my daughters sake. She is not showing any Celiac symptoms, but if she has a genetic marker for this, I think it would be good to know (OR if she DOESNT have the marker, I can stop worrying if she might get it). I call her my little "Carb-ovore" because she loves bread and pasta, would live on that if I let her. But she has no health issues that we know of and is fine on the growth chart, (actually 90%ile).

It would also be somewhat helpful for me to know if I am CELIAC or just Gluten Intolerant. Thanks in advance!

I used Enterolab and Kimball for genetic. This explains it well:

      GI DX celiac despite neg serology and no biopsy

      By Wheatwacked · Posted

      Just a gluten free diet is not enough.  Now you have to identify and replenish your malnutrition.  Celiac disease is co-morbid with malabsorption syndrome.  Low vitamin D, Low Thiamine caused Gastointeston Beriberi, low choline, low iodine are common the general population, and in newly diagnosed Celiacs in the western culture its is more likely.  It takes time to heal and you need to focus on vitamins and minerals.  Gluten free foods are not fortified like regular processed foods.

      Headaches / Migraines and Hypoglycaemia

      By Sarah Grace · Posted

      Dear Kitty Since March I have been following your recommendations regarding vitamins to assist with various issues that I have been experiencing.  To recap, I am aged 68 and was late diagnosed with Celiac about 12 years ago.  I had been experiencing terrible early morning headaches which I had self diagnosed as hypoglycaemia.  I also mentioned that I had issues with insomnia, vertigo and brain fog.   It's now one year since I started on the Benfotiamine 600 mg/day.  I am still experiencing the hypoglycaemia and it's not really possible to say for sure whether the Benfotiamine is helpful.  In March this year, I added B-Complex Thiamine Hydrochloride and Magnesium L-Threonate on a daily basis, and I am now confident to report that the insomnia and vertigo and brain fog have all improved!!  So, very many thanks for your very helpful advice. I am now less confident that the early morning headaches are caused by hypoglycaemia, as even foods with a zero a GI rating (cheese, nuts, etc) can cause really server headaches, which sometimes require migraine medication in order to get rid off.  If you are able to suggest any other treatment I would definitely give it a try, as these headaches are a terrible burden.  Doctors in the UK have very limited knowledge concerning dietary issues, and I do not know how to get reliable advice from them. Best regards,

      @rei.b,  I understand how frustrating starting a new way of eating can be.  I tried all sorts of gluten-free processed foods and just kept feeling worse.  My health didn't improve until I started the low histamine AIP diet.  It makes a big difference.   Gluten fits into opioid receptors in our bodies.  So, removing gluten can cause withdrawal symptoms and reveals the underlying discomfort.  SIBO can cause digestive symptoms.  SIBO can prevent vitamins from being absorbed by the intestines.  Thiamine insufficiency causes Gastrointestinal Beriberi (bloating, abdominal pain, nausea, diarrhea or constipation).  Thiamine is the B vitamin that runs out first because it can only be stored for two weeks.  We need more thiamine when we're sick or under emotional stress.  Gastric Beriberi is under recognised by doctors.  An Erythrocyte Transketolace Activity test is more accurate than a blood test for thiamine deficiency, but the best way to see if you're low in thiamine is to take it and look for health improvement.  Don't take Thiamine Mononitrate because the body can't utilize it well.  Try Benfotiamine.  Thiamine is water soluble, nontoxic and safe even at high doses.  I thought it was crazy, too, but simple vitamins and minerals are important.  The eight B vitamins work together, so a B Complex, Benfotiamine,  magnesium and Vitamin D really helped get my body to start healing, along with the AIP diet.  Once you heal, you add foods back in, so the AIP diet is worth doing for a few months. I do hope you'll consider the AIP diet and Benfotiamine.

      Finding gluten free ingredients

      By captaincrab55 · Posted

      Imemsm, Most of us have experienced discontinued, not currently available or products that suddenly become seasonal.   My biggest fear about relocating from Maryland to Florida 5 years ago, was being able to find gluten-free foods that fit my restricted diet.  I soon found out that the Win Dixie and Publix supper markets actually has 99% of their gluten-free foods tagged, next to the price.  The gluten-free tags opened up a  lot of foods that aren't actually marked gluten-free by the manufacture.  Now I only need to check for my other dietary restrictions.  Where my son lives in New Hartford, New York there's a Hannaford Supermarket that also has a gluten-free tag next to the price tag.  Hopefully you can locate a Supermarket within a reasonable travel distance that you can learn what foods to check out at a Supermarket close to you.  I have dermatitis herpetiformis too and I'm very sensitive to gluten and the three stores I named were very gluten-free friendly.  Good Luck
