Analysis of volatile organic compounds in breath as a potential diagnostic modality in disease monitoring [PDF]

open access: yes, 2011
The use of breath odours in medical diagnosis dates back to classical times, though in its modern form the technique is only a few decades old. There are several breath tests in common clinical use, though all of them involve administration of a known or

Exhaled breath condensate biomarkers in COPD [PDF]

open access: yesEuropean Respiratory Journal, 2008
Biomarkers in chronic obstructive pulmonary disease may be useful in aiding diagnosis, defining specific phenotypes of disease, monitoring exacerbations and evaluating the effects of drugs. Exhaled breath condensate is a noninvasive means of sampling the airways, allowing biomarkers of airway inflammation and oxidative stress to be measured.

Non-Invasive Estimation of Systemic Drug Exposure Using Exhaled Breath Metabolomics in Humans: A Translational Proof-of-Concept Study. [PDF]

open access: yesClin Pharmacol Ther
Accurate assessment of systemic drug exposure in humans remains challenging, as conventional approaches rely on intermittent blood sampling and laboratory‐based assays that are invasive and provide limited temporal resolution. Exhaled breath contains volatile and semi‐volatile compounds arising from drug metabolism and downstream biological processes ...

Collecting Protein Biomarkers in Breath Using Electret Filters: A Preliminary Method on New Technical Model and Human Study. [PDF]

open access: yesPLoS ONE, 2016
Biomarkers in exhaled breath are useful for respiratory disease diagnosis in human volunteers. Conventional methods that collect non-volatile biomarkers, however, necessitate an extensive dilution and sanitation processes that lowers collection ...

Simultaneous measurement of inhaled air and exhaled breath by double multicapillary column ion-mobility spectrometry, a new method for breath analysis: results of a feasibility study

open access: yesERJ Open Research, 2022
The high sensitivity of the methods applied in breath analysis entails a high risk of detecting analytes that do not derive from endogenous production.

An Exhaled Breath Sampler Based on Condensational Growth and Cyclone Centrifugation (BSCC)

open access: yesAerosol and Air Quality Research, 2022
An exhaled breath sampler based on condensational growth and cyclone centrifugation (BSCC) was developed and evaluated. The BSCC increases the size of exhaled breath aerosols through condensational growth and then collects them as liquid sample via ...

Cardiovascular Biomarkers in Exhaled Breath [PDF]

open access: yesProgress in Cardiovascular Diseases, 2012
With each breath that we exhale, thousands of molecules are expelled in our breath, giving individuals a "breath-print" that can tell a lot about them and their state of health. Breath analysis is rapidly evolving as the new frontier in medical testing.
