Dry skin, breakouts and rashes can all be signs of a food intolerance. With the Food Intolerance Test, a simple finger prick test will establish if you have any intolerances. You simply send your sample off to Cambridge Nutritional Sciences, who will give you a ‘yes or no’ answer to different food groups.

If you receive a positive result to having a food intolerance, you have choice more comprehensive tests from just £96. There are seven different options covering a wide variety of foods. They will use your same blood sample, and you will deal directly with the laboratory to organise your upgrade.
