Lactose intolerance is the most common food intolerance worldwide - in large parts of Africa and Asia, the majority of people cannot tolerate lactose. In the United Kingdom, studies show that eight per cent of the population is affected. They suffer from symptoms such as abdominal pain, nausea, flatulence and diarrhea when they eat foods containing lactose.

With the cerascreen® Lactose Intolerance Test, you can determine the concentration of hydrogen and methane in your breath after consuming a lactose solution. Your values from the test are then able to provide you with an indication of a possible lactose intolerance.
