This paper presents ammonia gas as a biomarker for different clinical conditions when it exceeds the normal concentration in the exhaled breath. In peculiar, detection of ammonia in human breath has the effort to investigate various practicabilities inclusive those comprising the kidneys, liver and bacterial infection of either the stomach or mouth. Laser spectroscopy, gas chromatography, photo-acoustic spectroscopy, chemical ionization, and chemical sensing are used to measure and detect ammonia gas from exhaled breath. These methods and techniques are discussed in terms of their response time and the minimum concentration detectable. Furthermore, the benefits and importance of these methods and their limitation and drawback are highlighted. [ABSTRACT FROM AUTHOR]
