Blood Test Question Re:diet


Team Young

Recommended Posts

Team Young Rookie

My son is on a gluten free diet and shows all the signs of Celiac. We are unwilling at this point to put him back on gluten for 3 mths to do a biopsy. He is 3 1/2. Our current diet is working for him and he is doing great.

His sister is 2 and has shown some signs of wheat intolerance just in the last few months. (Constipation, similar signs that her brother had before his symptoms got really severe). I took her off wheat and in 6 days her stools were soft again.

Our doctors are recommending we do a blood test on her b/c she should ideally still have gluten in her system. They are recommending putting her back on wheat for 2-4 weeks and then doing the celiac blood work up.

Here are my questions:

How much gluten do you need to have in your system daily in order for the blood work to be accurate? I feel like she did not have a large amount. Just grape nuts for breakfast and spelt bread for lunch.

How long...weeks do you need to be on gluten in order for the blood work to be accurate? I feel like no one knows the answer to this! The doctors are saying a month more for her.

Doesn't it make sense that if she is showing signs(constipation) then their should be enough gluten in her system to have an accurate blood work done?

I think my struggle as a mom is if she gets constipated and uncomfortable how long to let her endure that way. I want to get an accurate test done but certainly not at the expense of my daughter's comfort.

Thanks for your help.

I believe I asked this question myself once because I was having myself tested because my son and father both have Celiac and I have some stomach issues. I am gluten light because we eat mostly gluten free at home except for my lunch I eat at work. I was told that being gluten light can lead to a false negative on the blood work. I did test negative by the way. On the other hand, my son who tested positive was still showing a positive result 3 months after being gluten free.

It is my experience (though Im no expert - others on this board are much more experienced than me) that blood work in very young children is rarely accurate. If you get a positive result from blood tests in a child under 5 or in anyone actually, then there is no doubt that they have celiac however negative blood results, esp in children, dont always mean anything. It is hard to detect despite what some doctors say, My son had all the symptoms, behavioural and severe mood swings, no weight gain, pale skin, low immune system (not fighting anything) and problems with dairy products i.e. vomiting etc. He had negative blood results and i personally didnt want to put him through a biopsy as he is only five. I spoke to the celiac specialist who said its up to me and that if he was really reacting well to the diet, id have my answer. months on and he is gaining weight, he is healthier looking, he is happier and all round our lives have changed as a result. I suppose what im saying is that its a personal thing. If your children react well to the diet then perhaps that is all you need... although tests are always a good thing as they can rule out other problems too. I recommend you talk to a celiac specialist about this. other posters will be able to tell you how long you need to be on gluten for signs to show. some people say months! I wish you luck with whatever you decide and dont worry as all the mothers and fathers on this site have been through this particular dilemma

good luck

I would do the blood test now because it might end up positive and then you (and others) would know for sure. I would give her as much wheat as you/she were comfortable with until you did the test just to increase the chances of it being positive if there is a problem.

Then, because you know she is more comfortable gluten free, I would just have her follow the gluten-free diet and act as though she did have celiac.

My younger daughter showed signs of gluten intolerance/celiac her whole life. Her blood tests were always negative so I didn't do the strict gluten-free diet for her. When she was 8, we started being very strict with the gluten-free diet and she doesn't have GI issues any more. I wish I had known enough before then to insist on the strict diet.

I started her sister on the gluten-free diet without getting the blood test and know by dietary response that it is right for her, too. I haven't really had any problems so far with her doctors, teachers, relatives, etc., but having a positive blood test would just make the whole thing seem more legitimate to others.

I asked this question to Dr. Michelle Pietzak a little over a year ago. She told me at the time that an adult would need to consume two pieces of wheat bread, or equivalent amount of gluten, every day for 2 months. For a smaller child, about half of that. If you've been gluten free for only a month, the test may still not be accurate - if the damage was just beginning the antibody reaction may have already gone back to normal, even if the small intestine hasn't yet. Often the people who have high numbers after being gluten free for 3 or 6 months had very, very high numbers before starting the diet. My son had a number over 150 in one area (I think TTg but I can't remember with any certainty) and it took him 6 months to go down to normal. He was also REALLY sick, at a point where he was more or less starving to death. I know others had even higher numbers with little visible symptoms, too, so this disease varies greatly.

Hello Team Young,

I have asked this same question on this board. My son is 16 moths old and suffers from all of the common celiac symptoms. He has responded very well to a gluten free diet. The one consistent answer I have gotten regarding blood work is a negative test means nothing. We had a negative test and will test again in two months after we re-introduce him to gluten. I

      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.

      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? 
    • knitty kitty
      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 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!
