Blood Test

I appreciate (so much!) the feedback I've gotten on my earlier post. I made my husband just sit down and read it all.

We have not decided whether or not to do a Celiac blood test for our 4.5yo. (You'll recall that he has gluten & dairy intolerance as well as a gluten sensitive gene and the Celiac gene, per the Enterolab test.) I think I want to call my doctor tomorrow and ask some questions.

I was told by a friend that the standard blood tests used in doctors offices are not very accurate for Celiac and that I should insist on a particular test. She didn't tell me what it's called, only said that Prometheus Lab is the place to send it.

Can anyone explain to me the difference in blood tests and the name of the test I want to ask about? I'd like to ask our doctor if he uses the test and whether he would be willing to send it to Prometheus.

The tests they usually use to screen for Celiac are the tTG and total IgA. They usually always send these to either Prometheus or Mayo. Other tests to include on the screen are the EMA and AGA, antigliadin Igg and Iga. Good luck. Not sure if you got my email regarding the genes of your son. But you may want to look a little closer. According to what I saw I think he does not have a Celiac gene and unfortunately in the medical community they will tell you he could never have Celiac. They are still researching this, but right now the thought is you need to have those genes to have full blown Celiac. I strongly believe in gluten intolerance, which might best describe your little guy. I could be wrong, but check out his genes again. I think his genes were DQ1 and DQ3. Again, I'm not sure how accurate Enterolab is for gene testing, but that's what I got from your post. You could even give Enterolab a call. Good luck!

Again, I'm not sure how to read the Enterolab results. It says DQ 1,3 (subtype 6,8). I'm not sure which numbers go directly with the DQ. Is it the 1, 3, 6, or 8? My son's genetics were DQ 2,2 (subtype 2,2) so I knew it was a two. I apologize if I misread the results, but they seem confusing. I would give them a call. Good luck again!

Good luck. I think I read the results wrong. Hope you have good luck w/ your doc! :):)

I don't understand the number line either, but it looks like the subtypes are what count. I'm mostly going by the interpretation which they included on the same paper. Here's what it said. I bolded the part about Celiac:

Serologic equivalent: HLA-DQ 3,1 (Subtype 8,6)

Interpretation Of HLA-DQ Testing: HLA gene analysis reveals that you have one of the main genes that predisposes to gluten sensitivity and celiac sprue, HLA-DQ2 or HLA-DQ8. Each of your offspring has a 50% chance of receiving this gene from you, and at least one of your parents passed it to you. You also have a non-celiac gene predisposing to gluten sensitivity (DQ1 or DQ3 not subtype 8). Having one celiac gene and one gluten sensitive gene, means that each of your parents, and all of your children (if you have them) will possess at least one copy of a gluten sensitive gene. Having two copies also means there is an even stronger predisposition to gluten sensitivity than having one gene and the resultant immunologic gluten sensitivity or celiac disease may be more severe.

Thanks for the blood test info. I'm calling this morning.

      Have I got coeliac disease

      And I agree with Wheatwacked. When a physician tells you that you can't have celiac disease because you're not losing weight, you can be certain that doctor is operating on a dated understanding of celiac disease. I assume you are in the UK by the way you spelled "coeliac". So, I'm not sure what your options are when it comes to healthcare, but I might suggest...

      I have osteopenia and have cracked three vertebrae.  Niacin is connected to osteoporosis! Do talk to your nutritionist and doctor about supplementing with B vitamins.  Blood tests don't reveal the amount of vitamins stored inside cells.  The blood is a transportation system and can reflect vitamins absorbed from food eaten in the previous twenty-four to forty-eight hours.  Those "normal limits" are based on minimum amounts required to prevent disease, not levels for optimal health.   Keep us posted on your progress.   B Vitamins: Functions and Uses in Medicine https://pmc.ncbi.nlm.nih.gov/articles/PMC9662251/ Association of dietary niacin intake with osteoporosis in the postmenopausal women in the US: NHANES 2007–2018 https://pmc.ncbi.nlm.nih.gov/articles/PMC11835798/ Clinical trial: B vitamins improve health in patients with coeliac disease living on a gluten-free diet https://pubmed.ncbi.nlm.nih.gov/19154566/   Nutritional Imbalances in Adult Celiac Patients Following a Gluten-Free Diet https://pmc.ncbi.nlm.nih.gov/articles/PMC8398893/ Nutritional Consequences of Celiac Disease and Gluten-Free Diet https://www.mdpi.com/2036-7422/15/4/61 Simplifying the B Complex: How Vitamins B6 and B9 Modulate One Carbon Metabolism in Cancer and Beyond https://pmc.ncbi.nlm.nih.gov/articles/PMC9609401/

Anemia?  Do you take any supplements, or vitamins? I’m within healthy range for nutritional tests, thyroid and am not anemic. I do have osteopenia. I don’t take any medications, and the dietician was actually a nutritionist (not sure if that is the same thing) recommended by my physician at the time to better understand gluten free eating.    I almost wish the gluten exposure had triggered something, so at least I’d know what’s going on. So confusing!    Many thanks!

      @JudyLou,  I have dermatitis herpetiformis, too!  And...big drum roll... Niacin improves dermatitis herpetiformis!   Niacin is very important to skin health and intestinal health.   You're correct.  dermatitis herpetiformis usually occurs on extensor muscles, but dermatitis herpetiformis is also pressure sensitive, so blisters can form where clothing puts pressure on the skin. Elastic waist bands, bulky seams on clothing, watch bands, hats.  Rolled up sleeves or my purse hanging on my arm would make me break out on the insides of my elbows.  I have had a blister on my finger where my pen rested as I write.  Foods high in Iodine can cause an outbreak and exacerbate dermatitis herpetiformis. You've been on the gluten free diet for a long time.  Our gluten free diet can be low in vitamins and minerals, especially if processed gluten free foods are consumed.  Those aren't fortified with vitamins like gluten containing products are.  Have you consulted dietician?  Have you been checked for nutritional deficiencies?  Osteoporosis? Thyroid? Anemia?  Do you take any supplements, medicine, or vitamins? Niacin deficiency is connected to anemia.  Anemia can cause false negatives on tTg IgA tests.  A person can be on that borderline where symptoms wax and wane for years, surviving, but not thriving.  We have a higher metabolic need for more nutrients when we're sick or emotionally stressed which can deplete the small amount of vitamins we can store in our bodies and symptoms reappear.   Exposure to gluten (and casein in those sensitive to it) can cause an increased immune response and inflammation for months afterwards. The immune cells that make tTg IgA antibodies which are triggered today are going to live for about two years. During that time, inflammation is heightened.  Those immune cells only replicate when triggered.  If those immune cells don't get triggered again for about two years, they die without leaving any descendents programmed to trigger on gluten and casein.  The immune system forgets gluten and casein need to be attacked.  The Celiac genes turn off.  This is remission.    Some people in remission report being able to consume gluten again without consequence.   However, another triggering event can turn the Celiac genes on again.   Celiac genes are turned on by a triggering event (physical or emotional stress).  There's some evidence that thiamine insufficiency contributes to the turning on of autoimmune genes.  There is an increased biological need for thiamine when we are physically or emotionally stressed.  Thiamine cannot be stored for more than twenty-one days and may be depleted in as little as three during physical and emotional stresses. Mitochondria without sufficient thiamine become damaged and don't function properly.  This gets relayed to the genes and autoimmune disease genes turn on.  Thiamine and other B vitamins, minerals, and other nutrients are needed to replace the dysfunctional mitochondria and repair the damage to the body.   I recommend getting checked for vitamin and mineral deficiencies.  More than just Vitamin D and B12.  A gluten challenge would definitely be a stressor capable of precipitating further vitamin deficiencies and health consequences.   Best wishes!

I assume you are in the UK by the way you spelled "coeliac". So, I'm not sure what your options are when it comes to healthcare, but I might suggest you look for another physician who is more up to date in this area and is willing to work with you to get an accurate diagnosis. If, in fact, you do not have celiac disease but you know that gluten causes you problems, you might have NCGS (Non Celiac Gluten Sensitivity). There is no test available yet for NCGS. Celiac must first be ruled out. Celiac disease is an autoimmune disorder that damages the lining of the small bowel. NCGS we is not autoimmune and we know less about it's true nature. But we do know it is considerably more common than celiac disease.
