Advanced Nutrition Programme YorkTest Food Intolerance Test is a unique yes or no food intolerance test that quickly determines whether or not your health problem symptoms could be food related. Food intolerances can underlie many health problems including, bloating, tiredness, anxiety, constipation, diarrhea, headaches, migraine, water retention, hemorrhoids, depression, weight problem, IBS, acne, eczema and rosacea. The test is a unique home kit that enables you to obtain and send away a small blood sample for testing, with step by step instructions. Completed tests should be sent away to YorkTest Laboratories Ltd. This test doesn’t provide a list of different foods, but gives you a positive or negative result. If negative, you can rule out food as the problem. If positive, you will be contacted by YorkTest who will offer you the option of analysing your same blood sample to identify specific foods your are reacting to.
