Breath Hydrogen Testing in East and Southeast Asia.
Yao CK, et al. J Clin Gastroenterol 2018 - Review. PMID 29035975
Breath hydrogen tests are popular, noninvasive tests for the assessment of carbohydrate fermentation in patients with irritable bowel syndrome (IBS) and functional dyspepsia (FD). There is limited information regarding the utility of breath hydrogen and methane tests in IBS and FD patients in East and Southeast Asia. ...

Quality control for multiple breath washout tests in multicentre bronchiectasis studies: Experiences from the BRONCH-UK clinimetrics study.
O'Neill K, et al. Respir Med 2018. PMID 30509710
INTRODUCTION: Multiple Breath Washout (MBW) to measure Lung Clearance Index (LCI) is increasingly being used as a secondary endpoint in multicentre bronchiectasis studies. ...MBW tests with <2 technically valid and repeatable trials were deemed unacceptable to include in analysis. In accepted tests, values for LCI, LCI CV% and VT CV% before and after over-reading, were compared. ...

13C breath tests: visions and realities.
Klein PD. J Nutr 2001 - Review. PMID 11340131
Breath tests have been used in research laboratories for over 25 y. Originally, the tests were based on the use of (14)C, rather than on the nonradioactive isotope, (13)C. ...Thus far, the only test to be approved by the Food and Drug Administration is the (13)C-urea breath test. This manuscript describes the process by which approval is gained, and indicates the steps necessary for other tests to receive Food and Drug Administration approval....

Methods and functions: Breath tests.
Braden B. Best Pract Res Clin Gastroenterol 2009 - Review. PMID 19505663
Breath tests provide a valuable non-invasive diagnostic strategy to in vivo assess a variety of enzyme activities, organ functions or transport processes. Both the hydrogen breath tests and the (13)C-breath tests using the stable isotope (13)C as tracer are non-radioactive and safe, also in children and pregnancy. ...

[Breath tests in the diagnosis of gastrointestinal diseases].
Gisbert JP and González-Lama Y. Gastroenterol Hepatol 2005 - Review. PMID 16137476 Spanish.
Determination of carbon or hydrogen markers in breath has allowed closer investigation of the pathogenic mechanisms of several gastrointestinal diseases. ...Several breath tests have been developed that allow reliable evaluation of liver or exocrine pancreatic function, gastrointestinal motility, as related to gastric emptying or orocecal transit time, and a diagnostic approach to clinical problems that could be due to bacterial overgrowth or malabsorption of various sugars....

Potential use of metabolic breath tests to assess liver disease and prognosis: has the time arrived for routine use in the clinic?
Stravitz RT and Ilan Y. Liver Int 2017 - Review. PMID 27718326
This review, an expert opinion, summarizes background and recent data suggesting that metabolic breath tests may now meet these requirements and have a valid place in clinical hepatology to supplant the time-honoured assessment of hepatic fibrosis....

(13)C breath tests for the assessment of exocrine pancreatic function.
Braden B. Pancreas 2010 - Review. PMID 20861695
However, the costs of substrates, the high time expenditure, and the lack of standardization still limit the clinical use of these breath tests. This review aims to place into perspective the traditional pancreatic exocrine function tests and the newer (13)C breath tests....

Non-(13)CO2 targeted breath tests: a feasibility study.
Ruzsanyi V, et al. J Breath Res 2014. PMID 25358411
Breath tests allow a non-invasive and fast diagnostic of different specific enzymes' phenotypic functionality. Over the last decade several 13C-breath tests were successfully tested, with the (13)C-urea breath test being approved by the US Food and Drug Administration (FDA) and the European Medicines Agency (EMA). ...D3-acetone (m/z 62.08) appeared in exhaled breath concentrations up to 30 ppb (at maximum). Parallel consumption of ethanol seems to reduce the activity of the enzyme, resulting in approximately 15-30% reduction of the produced d3-acetone. ...

Breath acetone as a potential marker in clinical practice.
Ruzsányi V and Péter Kalapos M. J Breath Res 2017 - Review. PMID 28294105
Secondly, methods have emerged making possible its detection in exhaled breath, thereby offering an attractive alternative to investigation of blood and urine samples. From a clinical point of view the measurement of breath acetone levels is important, but there are limitations to its wide application. ...

[Modern breath analysis].
Wirtz LM, et al. Med Klin Intensivmed Notfmed 2019 - Review. PMID 30725273 German.
Modern breath analysis can detect very low concentrations of volatile components. Current research focuses on drug monitoring and diagnosis of various diseases. ...CONCLUSIONS: In the future, modern breath analysis could enable non-invasive drug monitoring and diagnostics of medical conditions relevant to intensive care medicine....
