Food Intolerance Tests by IntoleranceLab We use state-of-the-art American imported biotechnology equipment. Our full testing package will analyze your sample against over 350 foods and 350 non-foods. You’ll be given a list of the foods which score over 85% positive on our food reaction test. All you have to do is send us a few strands of your hair (about 9 or 10 is enough) https://www.facebook.com/intolerancelab/ https://www.intolerancelab.co.uk/ opening time: Monday to Friday 09:00 to 15:00 Saturday to Sunday Closed
