Analysis of exhaled air can measure the amount of certain gases, which can help diagnose or monitor a number of conditions. Hydrogen (H2) exhalation testers measure the hydrogen concentration in the patient's exhaled air, which allows the detection of lactose, fructose and other carbohydrate intolerances. Overgrowth of bacteria in the small intestine can also be determined with this type of test. The Smokerlyzer is used to measure the amount of carbon monoxide in smokers' breath. It is a tool for doctors to assess a patient's smoking status or nicotine dependence, and for smokers to help them quit.
