pustetester

Pustetester is a device or system used to analyze substances in a person’s exhaled breath. The term is used in several Nordic languages to refer to breath testing equipment, with applications ranging from law enforcement to medical diagnostics. Breath testing is valued for its non-invasive nature, speed, and potential for on-site results.

Technologies used in pustetesting vary by application and required accuracy. Common approaches include electrochemical sensors, such as fuel-cell detectors, which are widely used in consumer and professional breathalyzers to estimate alcohol levels. More sophisticated instruments employ infrared spectroscopy or laser-based methods, which can quantify a broader range of compounds in breath. In clinical settings, techniques like gas chromatography or specialized breath tests are used to diagnose conditions or monitor metabolic processes. Professional devices often require regular calibration and quality control to maintain reliability.

Applications of pustetesters include roadside or workplace alcohol testing, clinical diagnostics (for example, hydrogen or urea breath tests to detect infections or assess digestive function, and monitoring acetone in certain metabolic conditions). They are also used in research to study breath biomarkers associated with health and disease.

Limitations and regulatory considerations are important. Breath test results can be influenced by factors such as mouth alcohol, recent intake, ambient air, temperature, and device calibration. In many jurisdictions, breathalyzer readings used for legal purposes must meet approved standards and may require confirmatory blood tests or additional verification. Proper training, maintenance, and documentation are essential for reliable use.
