Exhaled biomarkers: a new report from the European Respiratory Society Task Force “Technical standard”
The new ERS recommendations for standardised exhaled biomarkers procedures are now available
The ERS Task Force “Technical standard” has been recently developed the new recommendations for standardised exhaled biomarkers procedures, such as the fraction of nitric oxide in expired gas (FeNO), volatile organic compounds (VOCs), variables in exhaled breath condensate (EBC) and other measurements. For FeNO and EBC, which official recommendations for standardised procedures were published more than 10 years ago, new developments and advances in technology have been discussed. Recommendations for exhaled VOCs and particles are published for the first time. The aim of the document is to provide technical standards and recommendations for sample collection and analytic approaches and to highlight future research priorities in this field. Studies regarding methodology of breath tests were selected, discussed and evaluated in a consensus-based manner by the Task Force members. Application of standardized breath biomarker measurement will provide comparable results, thereby facilitating the use of these biomarkers in clinical practice.
