Nutritional Consultations

When you receive your results, it may be daunting to know what to do next. Our food intolerance test comes with a free 30-minute consultation with one of our Nutritional Therapists. Within this consultation, we will advise you on what foods to eliminate from your diet, and help you find great alternatives so you can still enjoy mealtimes without experiencing the symptoms that come with a food intolerance or allergy. All of our consultations are bespoke; we can align recommendations with pre-existing diets (e.g. vegetarian, vegan), and we can also help recommend supplements to heal the gut from the effects of your intolerance.

Why Choose YorkTest

Featured In

* 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. YorkTest call their food-specific IgG tests “food intolerance” tests. 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 well 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.
