I would love to hear some opinions as to what are the best genetic test kits on the market for testing for the celiac/gluten genes? Which ones are the most extensive? Thank you!

i had mine done through enterolab (which on the results said testing was done through american red cross). got the "best deal" package or something like that but they offer genetic only testing.

Promethus is testing both alpha and beta chains, so you find out if you have the high-risk DQ2.5. I'm not sure Enterolab does that.

This is a pretty important factor. Anyone who has done the Enterolab test know if they test both parts?

Yes, genetic testing is only a percentile of probability, nothing more. And it's certainly not diagnostic. It CAN be used as a piece of a puzzle, but not solely independent.

I have never been a fan of Enterolabs, but I do understand that it can offer a piece to that puzzle...AFTER, other avenues have been exhausted.

Each have their own advantages.

Enterolab (Red Cross) tests by serology, and only beta chains, to keep costs down.

This is very accurate (someone here had DQ8 which a reputable lab missed, but Enterolab found it) , and you get to know all your DQ types. The other labs only look for DQ2 or DQ8.

Enterolab does test for DQ2,5, which is 0201. They can discriminate between DQ2,2 and DQ2,5. DQ2,2 is 0202.

Hi all- I just got my results back and it was done (or reported by) Quest. I don't have the official report yet- just the doctor's lab report, but mine said the following:

HLA-DQ2

(DQA1*05/DQB1*02) Positive

HLA-DQ8

(DQA1*03/DQB1*0302) Negative

HLA-DQA1* 02

HLA-DQA1* 05

HLA-DQB1* 0201

HLA-DQB1* 0202

------------------------------------------

Question-and help!: Which type of testing was this (serological?) - and could other labs do more "typing" or present more information? It looks like they tested for just the DQ2/DQ8- or did they do more (what are the 4 sets underneath the positive/negative lines)? Do I need to know more (like if they only look for HLA-DQ2 and HLA-DQ8, and one is negative, could there be one of the others - or is this all I need to know?) Does anyone know where we can learn more about interpreting these test results? For instance, people with homozygous vs. hetrozygous sets of these "phenotypes" may put some at higher risks for refractory celiac disease and for lymphoma. Thanks so much for your insight to this!

    • Awww Jhern...I'm sorry you are feeling so bad.  (((((Hugs))))) Please ask your Dr for a full thyroid panel to get a complete picture.  That includes TSH, free T4, free T3, TPOAb and TgAb...the last 2 are antibodies.  With a TSH that high, I would feel terrible...tired and achy for sure.  Most people, including me, feel best with their TSH around 1.  Some labs show an outdated range of .5-4.5.  I would bet that you would benefit from some thyroid medication. The weight gain could be from healing and absorbing nutrients too. I hope you get some answers and start feeling better soon!
    • Yes, elevated intra-epithelial lymphocytosis is a possible indication of Celiac disease. That’s what my biopsy said. “Moderate to marked villous blunting with moderate to marked intra-epithelial lymphocytosis and marked chronic inflammation of lamina propia….characteristic for untreated celiac…” What we are finding out about these medicines is incredible. I knew that it could damage the kidneys, and can cause fluid retention. It’s good you posted here. Yes, usually the order is indeed blood tests first then biopsy, but oh well. My own thinking about autoimmunity is starting to evolve more and more to incorporate the ideas of Dr Terry Wahls, namely that there is little real difference between the various chronic diseases, that at bottom, it all comes down to cellular health. "Cells need certain nutrients in order to do their work, otherwise they begin to malfunction, even die." “When you look at chronic disease on a cellular and molecular level, we see it’s all the same disease – too much oxidative stress, inflammation, and nutrient deficiencies, toxins that are present. We see it in mental health, neurodegeneration, autoimmunity. It’s remarkably similar. Treat at the cellular level.” Dr Terry Wahls. Plumbago  
    • Magnesium and Calcium intake down combination with high sodium would lead to a form of edema where your body retains water in the joints and muscles. Try drinking more green tea, vitamin C supplements, bioflavoids, and adding a bit of lemon juice (I use the true lemon powder) to foods and beverages. http://www.progressivehealth.com/5-vitamins-to-reduce-fluid-retention.htm
          OH for low sodium seasoning look up Big Axe Spices "http://bigaxespice.com/index.html"on amazon HUGE flavor no sodium. Or if you need more selection Spicely Organics. I did find a salt free habanero hot sauce I use in cooking for a few customers of mine that is salt free >.< Might help sweat it off lol http://shop.brobrubru.com/Original-African-Hot-Pepper-Sauce-Very-Hot-000019.htm   
    • Did they check for candida? And what about your other levels? Keep a eye on your food diary, start rotating foods a bit more, see if you got a new intolerance. They seem to random come and go with me like REALLY random...last month was lettuce which is fine when I brought it back yesterday.  Anyway other thoughts, make sure your getting a bit of everything, I sometimes slip and do not get enough vitamin A, Vitamin K, lycopene, selenium, or zinc when I rotate nuts, seeds, and veggies sometimes reaching a combination that is lacking one mineral or vitamin.   I really do find those "Super Foods" that you need to up a bit for me it is oddly nutritional yeast, kale, cocoa nibs, coconut, pumpkin seeds seem to really boost how I feel.   Sometime a probiotic and enzymes are a huge help.

      Might try a low carb (no fruit, grains, sugars, starchy veggies) for a week or two and There is this Candidia FX stuff on sale on Amazon that worked wonders for mine.
    • I can definately identify with this. I half-laughingly refer to myself as an 'elder orphan'.   I can't afford anything like a secret santa but would love the opportunity to exchange holiday cards with others here.  It is comforting in a way to realize that I am not the only person who is isolated but kind of sad to know that there are others in the same boat. When I talk to folks with large close extened families who endlessly complain about them I just want to slap them sometimes.
