A breath test is a type of test performed on air generated from the act of exhalation.[1]
Types include:
- Breathalyzer – by far the most common usage of this term relates to the legal breath test to determine if a person is driving under the influence of alcohol.
- Hydrogen breath test – it is becoming more and more common for people to undertake a medical test for clinical diagnosis of dietary disabilities such as fructose intolerance, fructose malabsorption, lactose intolerance and lactulose intolerance.
- The presence of Helicobacter pylori (in peptic ulcer disease) can be tested for with the urea breath test.
- Exhaled nitric oxide is a breath test that might signal airway inflammation such as in asthma.
- Breath tests for diseases have been developed for early detection of lung cancer, breast cancer, pulmonary tuberculosis and many others, to serve as an adjunct to existing medical tests. A trial will commence at Addenbrooke's Hospital in Cambridge, England to confirm the efficacy of these breath tests.[2] Phase II and Phase III clinical studies by Menssana Research, Inc. in The United States are also under way.[3]
