Blood Test Qustion

Ok, the test results, based off of blood work, for our 16 month old came back negative. The Dr. wants us to stay on the gluten free foods for about 2 months and then introduce him to gluten again. At that point, he will do another blood test. If this test comes back negative, there is a very good chance he does not have celiac. I know one thing, no negative testing, regarding this intolerance, is definitive.

This is the way I understand it, and please let me know if any body agrees or does not agree. They are testing for two antigens, DRQ2 or DRQ8. Neither of these were found in the last panel, but he had been on a gluten free diet for about 3 or 4 weeks. The next test will come after he has been introduced to gluten again. If he does have celiac disease, he should produce one of these antibodies that attaches to the gluten and causes damage to the small intestine. This would cause a positive result in the next test which would mean he probably does have celiac.

Has anybody out there gone through this procedure with their children? If so, has anybody had a negative result on the second test and their child still show an intolerance to gluten?

Thanks for reading,

Billy

They didn't explain this to you very well.

DRQ2 and 8 are the genes and they don't routinely test for those. The antibodies are:

anti-gliadin, anti-tissue transglutaminase, and anti-endomysial (sp). Except for the names, your understanding is correct.

I think you'll find that many parents couldn't handle the results when they tried to reintroduce their child to gluten and that response was definitive enough for them.

If they did gene testing, it is HLA DQ2 and HLA DQ8. They are the Celiac genes. They will be there/not there regardless of gluten intake.

The full Celiac panel is (blood/serology)

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

Total IgA level.

My son had these tests done

Anti-gliadin antibodies (AGA) both IgA and IgG

Anti-endomysial antibodies (EMA) - IgA

Anti-tissue transglutaminase antibodies (tTG) - IgA

They all came back negative except for the IgG one which I was told means it was inconclusive or negative however you want to look at it. My son was gluten lite when he took it and those #'s were high then I put in on a high gluten diet and those same #'s were still high. He has a ton of GI symtoms so we were told and decided to challenge him on the gluten-free diet. I basically am trying my best to treat him as tho he is truely celiac....we have had a few mishaps with cross contaiminations. But he is looking a bit better. The couple of times before we went strict gluten-free I gave him non gluten-free cookies or gold fishes and he instantly complained of tummy pain. My son is 3.5 yrs old. I have no doubt my son has a gluten intollerence...whether or not it is celiac is where I am stuck. I would love to get the gene test done but my doctor has swayed not to.

Good luck. I've been reading alot and from what I understand testing young kids under age 6 you often get false negitives.

We're in the exact same boat (no positives except moderately high IgG). He has improved so much gluten free, but it is frustrating not knowing definitively. Have you made any other discoveries? Our son was treated for yeast, and the response was very positive. I guess that is controversial, though.

      Thanks again for the detailed explanation. Just to clarify, I actually did have my initial tests done while I was still consuming gluten. I stopped eating gluten only after those tests were completed, and it has now been about 70 days since I went gluten-free.

      Blood tests for thiamine are unreliable. The nutrients from your food get absorbed into the bloodstream and travel around the body. So, a steak dinner can falsely raise thiamine blood levels in the following days. Besides, thiamine is utilized inside cells where stores of thiamine are impossible to measure. A better test to ask for is the Erythrocyte...

      Neither of them were anemic 6 months after the Celiac diagnosis. His other vitamin levels (d, B12) were never low. My daughters levels were normal after the first 6 months. Is the thiamine test just called thiamine?

      Yes, I do think they need a Thiamine supplement at least. Especially since they eat red meat only occasionally. Most fruits and vegetables are not good sources of Thiamine. Legumes (beans) do contain thiamine. Fruits and veggies do have some of the other B vitamins, but thiamine B 1 and Cobalamine B12 are mostly found in meats. Meat, especially organ...

      Thank you! That's helpful. My kids eat very little processed food. Tons of fruit, vegetables, cheese, eggs and occasional red meat. We do a lot of rice and bean bowls, stir fry, etc. Do you think with all the fruits and vegetables they need a vitamin supplement? I feel like their diet is pretty healthy and balanced with very limited processed food....

      High TTG-IgG and Normal TTG-IgA

      Thanks again for the detailed explanation. Just to clarify, I actually did have my initial tests done while I was still consuming gluten. I stopped eating gluten only after those tests were completed, and it has now been about 70 days since I went gluten-free. I understand the limitations around diagnosing NCGS and the importance of antibody testing and biopsy for celiac disease. Unfortunately, where I live, access to comprehensive testing (including total IgA and endoscopy with biopsy) is limited, which makes things more complicated. Your explanation about small-bowel damage, nutrient absorption, and iron-deficiency anemia still aligns closely with my history, and it’s been very helpful in understanding what may be going on. I don't wanna get Endoscopy and I can't start eating Gluten again because it's hurt really with severe diarrhea.  I appreciate you taking the time to share such detailed and informative guidance. Thank you so much for this detailed and thoughtful response. I really appreciate you pointing out the relationship between anemia and antibody patterns, and how the high DGP IgG still supports celiac disease in my case. A gluten challenge isn’t something I feel safe attempting due to how severe my reactions were, so your suggestion about genetic testing makes a lot of sense. I’ll look into whether HLA testing is available where I live and discuss it with my doctor. I also appreciate you mentioning gastrointestinal beriberi and thiamine deficiency. This isn’t something any of my doctors have discussed with me, and given my symptoms and nutritional history, it’s definitely worth raising with them. I’ll also ask about correcting deficiencies more comprehensively, including B vitamins alongside iron. Thanks again for sharing your knowledge and taking the time to help. I’ll update the forum as I make progress.

      Blood tests for thiamine are unreliable.  The nutrients from your food get absorbed into the bloodstream and travel around the body.  So, a steak dinner can falsely raise thiamine blood levels in the following days.  Besides, thiamine is utilized inside cells where stores of thiamine are impossible to measure. A better test to ask for is the Erythrocyte Transketolace Activity test.  But even that test has been questioned as to accuracy.  It is expensive and takes time to do.   Because of the discrepancies with thiamine tests and urgency with correcting thiamine deficiency, the World Health Organization recommends giving thiamine for several weeks and looking for health improvement.  Thiamine is water soluble, safe and nontoxic even in high doses.   Many doctors are not given sufficient education in nutrition and deficiency symptoms, and may not be familiar with how often they occur in Celiac disease.  B12 and Vitamin D can be stored for as long as a year in the liver, so not having deficiencies in these two vitamins is not a good indicator of the status of the other seven water soluble B vitamins.  It is possible to have deficiency symptoms BEFORE there's changes in the blood levels.   Ask your doctor about Benfotiamine, a form of thiamine that is better absorbed than Thiamine Mononitrate.  Thiamine Mononitrate is used in many vitamins because it is shelf-stable, a form of thiamine that won't break down sitting around on a store shelf.  This form is difficult for the body to turn into a usable form.  Only thirty percent is absorbed in the intestine, and less is actually used.   Thiamine interacts with all of the other B vitamins, so they should all be supplemented together.  Magnesium is needed to make life sustaining enzymes with thiamine, so a magnesium supplement should be added if magnesium levels are low.   Thiamine is water soluble, safe and nontoxic even in high doses.  There's no harm in trying.

Most fruits and vegetables are not good sources of Thiamine.  Legumes (beans) do contain thiamine.  Fruits and veggies do have some of the other B vitamins, but thiamine B 1 and  Cobalamine B12 are mostly found in meats.  Meat, especially organ meats like liver, are the best sources of Thiamine, B12, and the six other B vitamins and important minerals like iron.   Thiamine has antibacterial and antiviral properties.  Thiamine is important to our immune systems.  We need more thiamine when we're physically ill or injured, when we're under stress emotionally, and when we exercise, especially outside in hot weather.  We need thiamine and other B vitamins like Niacin B 3 to keep our gastrointestinal tract healthy.  We can't store thiamine for very long.  We can get low in thiamine within three days.  Symptoms can appear suddenly when a high carbohydrate diet is consumed.  (Rice and beans are high in carbohydrates.)  A twenty percent increase in dietary thiamine causes an eighty percent increase in brain function, so symptoms can wax and wane depending on what one eats.  The earliest symptoms like fatigue and anxiety are easily contributed to other things or life events and dismissed.   Correcting nutritional deficiencies needs to be done quickly, especially in children, so their growth isn't stunted.  Nutritional deficiencies can affect intelligence.  Vitamin D deficiency can cause short stature and poor bone formation.   Is your son taking anything for the anemia?  Is the anemia caused by B12 or iron deficiency?

      Thank you! That's helpful. My kids eat very little processed food. Tons of fruit, vegetables, cheese, eggs and occasional red meat. We do a lot of rice and bean bowls, stir fry, etc.  Do you think with all the fruits and vegetables they need a vitamin supplement? I feel like their diet is pretty healthy and balanced with very limited processed food. The only processed food they eat regularly is a bowl of Cheerios here and there.  Could shaking legs be a symptom of just a one-time gluten exposure? I guess there's no way to know for sure if they're getting absolutely zero exposure because they do go to school a couple times a week. We do homeschool but my son does a shared school 2x a week and my daughter does a morning Pre-K 3 x a week.  At home our entire house is strictly gluten free and it is extremely rare for us to eat out. If we eat at someone else's house I usually just bring their food. When we have play dates we bring all the snacks, etc. I try to be really careful since they're still growing. They also, of course, catch kids viruses all the time so I  want to make sure I know whether they're just sick or they've had gluten. It can be pretty confusing when they're pretty young to even be explaining their symptoms!
