The IFCC Emerging Technology Division (ETD) is dedicated to providing current awareness for emerging technologies likely to have important clinical diagnostic applications in the near future. One of those technologies is volatolomics (breathomics) i.e., breath analysis.
This web page will provide a regularly updated perspective on the emerging clinical diagnostic applications of volatolomics over the next 3 years.
Breath analysis is not new and already has a few, but very specific applications (e.g., breath alcohol testing, hydrogen, carbon monoxide, oxygen, carbon dioxide, nitric oxide, and nitrous oxide testing, 13carbon/12carbon-based tests)(https://www.ncbi.nlm.nih.gov/pmc/articles/PMC2990505/).
The types of breath analysis can be subdivided into:
Current work on volatolomics centers on finding diagnostic utility in the pattern of compounds (VOCs) in breath. Breath analysis is an attractive proposition because this type of testing is non-invasive, applicable to the point-of-care and offers the possibility of real-time clinical management.
Already, there are more than 10 companies focused on the clinical diagnostic applications of volatolomics employing diverse analytical technologies (breath analysis analyzers are sometimes known as “electronic noses”). The broad range of diagnostic applications under investigation and development ranges from breath glucose testing to testing for different types of cancer.
Breath analysis technologies are diverse and include different types of mass spectrometry [e.g., gas isotope ratio mass spectrometry (GIRMS), selected ion flow tube mass spectrometry (SIFT-MS), field asymmetric ion-mobility spectrometry (FAIMS), secondary electro-spray ionization-MS], sensors and sensor arrays (e.g., copper bromide-based sensor, colorimetric high dimensional sensor array), gas chromatography (e.g., GC SAW). Further notable aspects of breath analysis technologies are the use of artificial intelligence, cloud-based analysis of data and analyzers that link to a
The scope and content of this web page will include:
1. News items and opinion pieces from key researchers/opinion leaders about recent developments in the clinical diagnostic applications of volatolomics.
2. A directory of companies active in the clinical diagnostic applications of volatolomics.
3. Links to clinical trials involving volatolomic testing.
4. Details of analyzers and regulatory approvals of clinical diagnostic products based on volatolomic testing.
5. A literature survey updated quarterly designed to provide an educational resource and a snapshot of work since 2010.
Breath alcohol testing, and associated hand-held alcohol meters (breathalyzers), is now a mature sector of breath analysis, as is breath testing for oxygen, CO2, and nitrous oxide, and these will not be considered here in any detail.
The web page has been developed in conjunction with key researchers and companies active in clinical applications of breath analysis. A particular feature of this webpage will be regular updates based on feedback from our readers.
