Wheat Gluten Intolerance Test - Celiac Test

Product Information

For children,you can mix wheat flour into foods such as yogurt or baked beans to add more gluten into their diet. There are many different types of food intolerances which more commonly affect people than a food allergy. It is important to understand that not all reactions to food are because of a food allergy. Common types of food intolerances include reacting to lactose, gluten, food additives and chemicals. Histamine intolerance IgA Endomysial antibody (EMA): The EMA test has a specificity of almost 100%, making it the most specific test for celiac disease, although it is not as sensitive as the tTG-IgA test. About 5-10% of people with celiac disease do not have a positive EMA test. It is also very expensive in comparison to the tTG-IgA and requires the use of primate esophagus or human umbilical cord. It is usually reserved for difficult to diagnose patients. Alternative tests may claim to diagnose food related ‘problems’, allergies or intolerances, but they are not used for coeliac disease.

While it is very rare, it is possible for someone with celiac disease to have negative antibody test results. If your tests were negative, but you continue to experience symptoms, consult your physician and undergo further medical evaluation. The symptoms of non coeliac gluten sensitivity may be similar to those experienced by people with coeliac disease, but it is not clear how the immune system might be involved and there does not appear to be damage to the lining of the gut. What is the difference between the conditions? This information was published by Bupa's Health Content Team and is based on reputable sources of medical evidence. It has been reviewed by appropriate medical or clinical professionals and deemed accurate on the date of review. Photos are only for illustrative purposes and do not reflect every presentation of a condition.More research is needed to explore the effects of a low histamine diet. The diet is therefore not currently recommended in the management of Long COVID. Lactose intolerance Lactose intolerance is treated by following a low lactose diet. Most children and adults with lactose intolerance can tolerate small amounts of lactose in foods. Lactose may act as a prebiotic – feeding healthy gut bacteria and improving the absorption of minerals such as calcium, so try to include it if you can. If you continue to have symptoms of coeliac disease, despite having a negative blood test, the GP may still refer you to a specialist. Biopsy Some people may start to reduce or eliminate gluten from their diet because they feel ill. Unfortunately this is very likely to cause an inaccurate result for both the blood test and the gut biopsy.

In response to the Covid-19 pandemic, the British Society of Gastroenterology have published interim guidance on diagnosis of coeliac disease in adults. The diagnosis of coeliac disease should be made by a gastroenterologist.

Histamine occurs naturally in many foods and a low histamine diet can potentially be very restrictive, leading to nutritional deficiencies if not supported correctly by a dietitian. Conclusion You may have a wheat intolerance, which means you experience symptoms when you eat foods containing wheat, possibly for several hours afterwards. The gastroenterologist will pass a tiny biopsy tool through the endoscope to take samples of the lining of your small intestine. The sample will then be examined under a microscope for signs of coeliac disease. Tests after diagnosis You can learn more about coeliac disease and receive practical advice about following a gluten-free diet from your local coeliac disease support group.NHS guidance is that you should only restrict your child's diet on the advice of your GP or a registered dietician. So if you're worried that your child may have a food intolerance or coeliac disease, you should visit your GP as soon as possible. A thin, flexible tube with a light and camera at one end ( endoscope) will be inserted into your mouth and passed down to your small intestine.
