Should I Ask For A Blood Retest?

I recently had a blood test for celiac disease that came out negative. However, I had already been following a gluten-free diet for two weeks beforehand, and my doctor told me that was OK. I've recently read that you need to be on a full-on gluten-containing diet for the test to be reliable. Should I ask for a retest? In some ways I'd like to find out for sure what is wrong with me so I can stop trying to hunt for possible causes. On the other hand, I don't want to make myself sick again. Also, the test is pretty expensive and I have to pay for it.

FYI, going gluten-free has helped a lot, but I'm still experiencing some symptoms. However, I only started trying to eliminate dairy in the last 24 hours. I feel like celiac disease "fits" my symptoms better than anything else I've ever heard of.

Antibody levels can take months to fall. A couple weeks probably didn't have a significant effect.

And some people test false negative on bloodwork, no matter how much gluten they eat. You need to get a copy of your labs and see which tests were run. Then take it from there.

And some can have the levels fall very quickly especially if the levels were a low positive to begin with. You also could have a false negative. If you want to get retested go back on gluten for a couple of months and retest. Also be sure to get your hands on the actual copies of the results as some doctors will call a low positive a negative. When you are done with all testing then do the diet strictly for at least a couple of months and see what happens. With the high false negative rates and the fact that your primary complaint is joint related your joints may be being impacted more than your gut by the inflammation. In the end your body knows the answer.

      Toddler recently diagnosed with Type 1 diabetes and need help understanding coeliac screening test results

       In terms of a low carb diet the thing to remember is that it is not a “no carb” diet. Far from it. There are a lot of misconceptions. Real food is the key. Avoiding refined sugars and starches. In the textbook that doctors use it states that “Carbohydrates” are not essential to life, unlike proteins and fats. Glucose on the other hand is essential, yes, and the liver makes and tightly regulates all it needs in the presence of adequate calories from proteins and fats. It’s biochemistry 101.  My personal view is that the NHS advice is out of date. And no wonder the life expectancy and quality of life of people with diabetes down the road is reduced - not to mention the cost to the NHS when complications arise decades after diagnosis because too much insulin to keep numbers in range is like a bandage to cover up while under the surface the damage is still going on. Retinopathy. Peripheral neuropathy. Sorry, don’t want to doom and gloom. But it’s true. The fuel you choose today dictates tomorrow. The information is out there in the scientific papers. It’s a can of worms but there is decades of scientific literature to back up a natural low carb diet. Professor Tim Noakes of Cape Town university went through a three year trial (and won) after a dietitian accused him because he recommended weaning a child on to meat after breastfeeding. They said they needed carbohydrates. He’s a professor of sports and exercise and medical doctor with diabetes. There’s a whole host of Professors and medical doctors and dietitians and medical professionals around the world advocating for real food and essentially a low carb diet. Humans evolved over millennia on real food. None of the modern high carb ultra processed or modern breads of the last century or so. Check out the Public Health Collaboration UK based charity. There’s conference videos online and free info. I think type 1 diabetes was covered a few years ago. Dr David Cavan UK specialist. Professor Knoakes also came out with a great cookery book called Superfood for Superchildren…from toddlers to teens. It is part of the Real Meal Revolution series of healthy eating. It sounds like youre on this already with breastfeeding and eating healthy so good on you! So sorry about the cards your little one has been dealt but with the right education and diet it is totally manageable and there’s no reason not to have stable blood sugars and have a long and happy life without diabetes complications. Same as children diagnosed with coeliac disease, a healthy naturally gluten free diet is the antidote to the gluten poisoning. Sugar and refined starches are toxic to diabetics. With modern technology of blood glucose monitors it’s easy to figure out suitable foods by how different foods effect the blood glucose level. Sorry, the reference of igA deficiency possibility was to Trent’s reply regarding Total igA and “artificially low” positive test. Not the case as the NHS screen total igA. In terms of poo signs. The Guts UK charity has loads of great info.

      Hair loss is also a symptom of thiamine insufficiency.     Peripheral neuropathy, another thiamine insufficiency symptom, can cause a feeling of itchiness on the skin without a rash.

      Celiac testing often includes looking at total IgA levels, because if someone is deficient the IgA tests for celiac disease may not be accurate (false negatives).  Did her doctors say anything about how much gluten she should consume?  If you change that it could affect her next test results.

      @mytype1diabetes, Do keep in mind that Celiac Disease is genetic, so all first degree relatives (parents, siblings) should be checked for celiac disease as well.   Thiamine deficiency is common in breastfeeding mothers and their babies, even in countries where people are well fed and eat healthy.  A high carbohydrate diet requires more thiamine to turn those calories into energy.  Mothers on a high carbohydrate diet can be deficient in thiamine which also causes the infant to be deficient. DKA is found in children with thiamine deficiency.   Thiamine deficiency correction is part of DKA treatment. Thiamine deficiency needs to be addressed and corrected quickly and maintained.  Ask for an Erythrocyte Transketolace test for thiamine deficiency. I've experienced this myself.  Diabetics continue to lose thiamine due to poor renal uptake. Thiamine should be supplemented daily.  Thiamine is a constant in my life which helps immensely with my diabetes.   References: Thiamine deficiency in pregnancy and lactation: implications and present perspectives https://pmc.ncbi.nlm.nih.gov/articles/PMC10158844/ Pediatric thiamine deficiency disorders in high‐income countries between 2000 and 2020: a clinical reappraisal https://pmc.ncbi.nlm.nih.gov/articles/PMC9290709/ Hiding in Plain Sight: Modern Thiamine Deficiency https://pmc.ncbi.nlm.nih.gov/articles/PMC8533683/ The Impact of Thiamine Treatment in the Diabetes Mellitus   https://pmc.ncbi.nlm.nih.gov/articles/PMC3376872/#:~:text=Low plasma thiamine level was,increase in thiamine transporter expression.

      Thanks for this Wends and appreciate your insights! I'm not sure what you mean by "Your toddler is unlikely igA deficient with a titer of 22, as a positive test." ? I had a look at Dr Bernstein's work and we've definitely noticed that on lower carb days her blood glucose levels are much easier to manage. Our nutritionist advised against a low carb diet for toddlers as they said young children, unlike adults, rely on carbs for their growth and development. What's your view on this? Regarding malabsorption - it's so hard to know what's "normal". My daughter's poos have always been on the softer side as she's breastfed and we eat very healthily. I've booked an appointment with our GP and will take some photos!
