There are several potential medicinal and scientific uses for breath analysis, a relatively new field of inquiry. The environment, microorganisms in the gut and airways, and metabolites of ingested precursors all contribute to the body's internal production of volatile organic compounds (VOCs) that are detected in breath. Several recent studies suggest that breath analysis may aid in the diagnosis of illnesses associated with alterations in breath composition. Infrared spectroscopy is a promising analytical method for the metabolic analysis of breath. There are substances in human breath that can be used to assess environmental exposure, diagnose diseases, and monitor physiological conditions. Exhaled breath promotes collaboration and is the ideal biological fluid because it is nearly limitless and causes little to no discomfort for the patient. Breath analysis is a suitable technique for certain applications, as exhaled breath can be captured without the need for medical personnel or privacy, and it typically doesn't produce infectious waste (although airborne infections may be present). Breath analysis is a non-invasive technique that reveals the overall health and condition of the body's metabolism by describing the volatile content of the bloodstream and airways using the volatile composition of exhaled breath (EB). However, because exhaled breath includes relatively little of the metabolites, the absorption strength of the metabolites is still quite moderate. This chapter presents recent applications of the infrared spectroscopic technique published between 2020 and 2025.
