Best Genetic Tests?

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?

no, just one ... its in their FAQ area of their website i believe and i think i remember it *may* tell why they only do one portion. :)

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!

      Recovery from gluten challenge

      Thank you so much for your response! I have a follow-up appointment with her pediatrician next week, and also an appointment with her pediatric GI Dr. Your message gives me some ideas for questions to ask the doctors. My daughter went strictly gluten-free in January following her first endoscopy so I’m guessing her diet is pretty solid. She is compliant b...

      Recovery from gluten challenge

      While the positive endoscopy confirms the diagnosis, it's important to be skeptical of the idea that your daughter will simply "bounce back" to a pre-challenge state. The gluten challenge was essentially a controlled, prolonged exposure that likely caused significant inflammation and damage to her system; it's not surprising that recovery is slow and that...

      Brain fog

      The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium. Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend...

      Were you doing any of the new home construction yourself? Drywall compounds and adhesives used in construction have been known to cause problems for some celiacs.

      Thanks to those who have replied.  To Cristina, my symptoms are as follows: Dizziness, lightheaded, headaches (mostly sinus), jaw/neck pain, severe tinnitus, joint stiffness, fatigue, irregular heart rate, post exercise muscle fatigue and soreness, brain fog, insomnia.  Generally feeling unwell. To Trents, We didn’t do any of the construction but did visit the job site quite often.  While getting the old house ready we stirred up a lot of dust and I’m sure mold but haven’t been back there for over a month.

      Thank you so much for your response! I have a follow-up appointment with her pediatrician next week, and also an appointment with her pediatric GI Dr. Your message gives me some ideas for questions to ask the doctors. My daughter went strictly gluten-free in January following her first endoscopy so I’m guessing her diet is pretty solid. She is compliant but also reliant on others to make her food (at school and home) but she didn’t have this problem prior to the gluten challenge when she went strictly gluten-free. It really makes sense to me that the gluten challenge inflammation hasn’t healed and I will be asking her doctors about nutritional issues. I ask for anecdotal stories because the research surrounding the gluten challenge seems to be inconsistent and inconclusive (at least what I’ve been able to find!). Thank you so much for your response!

      While the positive endoscopy confirms the diagnosis, it's important to be skeptical of the idea that your daughter will simply "bounce back" to a pre-challenge state. The gluten challenge was essentially a controlled, prolonged exposure that likely caused significant inflammation and damage to her system; it's not surprising that recovery is slow and that a subsequent exposure hit her so hard. The persistent fatigue is a major red flag that her body is still struggling, potentially indicating that the initial damage hasn't fully healed or that her system is now in a heightened state of reactivity. Rather than seeking anecdotal timelines from others, her experience underscores the critical need for close follow-up with her gastroenterologist to rule out other nutrient deficiencies commonly caused by celiac flare-ups, like iron or B12, and to consult with a dietitian to scrutinize her diet for any hidden sources of cross-contamination that could be perpetuating her symptoms. The most common nutrient deficiencies associated with celiac disease that may lead to testing for the condition include iron, vitamin D, folate (vitamin B9), vitamin B12, calcium, zinc, and magnesium.  Unfortunately many doctors, including my own doctor at the time, don't do extensive follow up testing for a broad range of nutrient deficiencies, nor recommend that those just diagnosed with celiac disease take a broad spectrum vitamin/mineral supplement, which would greatly benefit most, if not all, newly diagnosed celiacs.

Brain fog, like other celiac disease symptoms, does improve after you to 100% gluten-free, and supplementation will also help.
