Breath Analysis: Comparison among Methodological Approaches for Breath Sampling

Breath Analysis in Disease Diagnosis: Methodological Considerations and Applications

Breath analysis is a promising field with great potential for non-invasive diagnosis of a number of disease states. Analysis of the concentrations of volatile organic compounds (VOCs) in breath with an acceptable accuracy are assessed by means of using analytical techniques with high sensitivity, accuracy, precision, low response time, and low detection limit, which are desirable characteristic...

Methodological and physiological aspects of exhaled breath analysis

Optimisation of sampling parameters for standardised exhaled breath sampling.

The lack of standardisation of breath sampling is a major contributing factor to the poor repeatability of results and hence represents a barrier to the adoption of breath tests in clinical practice. On-line and bag breath sampling have advantages but do not suit multicentre clinical studies whereas storage and robust transport are essential for the conduct of wide-scale studies. Several device...
