The analysis of exhaled breath, as an alternative to sputum-dependent tests, has the potential to provide a simple, fast, non-invasive, and readily available diagnostic service that could positively change TB detection. A total of 50 individuals from a clinic in South Africa were included in ...
Breath condensateSolid-phase microextraction (SPME) was applied, in conjunction with gas chromatography–mass spectrometry, to the analysis of volatile organic compounds (VOCs) in human breath samples without requiring exhaled breath condensate collection. A new procedure, exhaled breath vapor (EBV) ...
The concentration measurements of exhaled breath biomarkers using the QEPAS technique in the 8 渭m spectral region agreed with the blood glucose and blood ammonia measurements. The measurement limit and sensitivity met the requirement of the breath gas analysis needed to distinguish the concentrations ...

The present embodiments disclose a device including a module for sampling, separating and enriching a detected object, an exhaled breath condensates (EBCs) detection module and a combined volatile organic compounds (VOCs) detection module. The sampling module is connected with the EBCs detection modul...
Recently, the possibility of direct human breath analysis was demonstrated using extractive electrospray ionization mass spectrometry (EESI-MS)21. In many cases, EESI-MS requires no/minimal sample pretreatment and allows sensitive detection of both volatile and non-volatile compounds in exhaled breath in...

In addition to exhaled breath, urine is also considered to be a potential source of VOCs. However, one issue associated with the analysis of urine is the potential that VOCs detected in urine samples are derived from exogenous sources such as diet or the environment rather than as a result ...
