It depends on your circumstances. If you’re experiencing altered bowel habits and you haven’t seen your doctor, then we would usually recommend that you discuss your symptoms with them first as they may want to carry out some blood and stool tests. If you haven’t been able to do this before your appointment then don’t worry as we can arrange these tests with your doctor, or privately if you prefer.nWe never recommend food intolerance tests, as these are not supported by robust scientific evidence. Read our blog post for more info. If you think you have a food intolerance please discuss this with your dietitian and they will explain how these are diagnosed and treated.nWhen it comes to stool microbiome tests, the science just isn’t there yet to give results that you can meaningfully work with, so we don’t tend to recommend these. If you are interested in these GI mapping tests please discuss with your dietitian as we can arrange these privately for you.nIf you’re interested in getting their DNA tested to discover what disease risks are influenced by your genes and lifestyle, let us know as we can arrange this for you. The test also reveals your personalised impact on vitamins, nutrients and predisposition to gluten, lactose, caffeine and alcohol intolerance.nIf you suspect Small Intestinal Bacterial Overgrowth (SIBO) then we can arrange the test for you privately using a credible laboratory that offers in-person as well as postal test kits. Please discuss this with your dietitian.
