* YorkTest has 40 years of experience in optimising health and wellbeing. YorkTest provide laboratory test results and nutritional support services for informational purposes only and are not a substitute for professional medical advice. The results provided cannot be used to diagnose, treat or cure medical or health conditions. The term “food intolerance” is used broadly to reflect that IgG antibody reactions to foods are measured by the YorkTest laboratory. These “food intolerance” tests are not allergy, lactose intolerance or coeliac tests. YorkTest recognise that food-specific IgG test results cannot be used to diagnose, treat or cure any specific food intolerances. YorkTest also recognise that the link between raised food-specific IgG levels, gut health and specific symptoms is not fully understood and for this reason YorkTest always provide a Nutritional Therapist consultation to help guide an elimination diet. If you are concerned about your symptoms then please contact your GP.
