Hengitystestit, or breath tests, are diagnostic procedures that analyze the composition of exhaled breath to assess various physiological conditions. These tests can detect a range of substances in the breath, providing non-invasive insights into metabolic processes, organ function, and the presence of certain microorganisms.

One common application of breath tests is in the diagnosis of Helicobacter pylori infection, a bacterium that can cause stomach ulcers and gastritis. In this type of test, the patient drinks a solution containing a labeled urea molecule. If H. pylori is present, it breaks down the urea, releasing labeled carbon dioxide that is then detected in the exhaled breath.

Breath tests are also used to evaluate gastrointestinal motility and absorption. For example, lactose intolerance can be diagnosed by measuring the hydrogen or methane produced by gut bacteria after consuming lactose. Similarly, tests for small intestinal bacterial overgrowth (SIBO) involve analyzing specific gases in the breath after ingesting a sugar substrate.

Beyond gastrointestinal health, breath analysis can offer information about liver function, lung disease, and even metabolic disorders like diabetes. The development of more sensitive and specific breath analyzers continues to expand the diagnostic potential of these tests, offering a convenient and patient-friendly approach to medical evaluation. The interpretation of breath test results typically requires a healthcare professional to correlate the findings with the patient's clinical presentation.
