BreathSpec study
A multicentre prospective, observational, longitudinal cohort study in adult patients with suspected upper or lower respiratory infection (URTI/LRTI) to identify a spectrum of biomarkers in exhaled breath to discriminate participants with bacterial RTI from participants without.
Identification of chemical biomarkers in exhaled breath that potentially discriminates participants with bacterial RTI from participants without.
Additional endpoints explored will be variations of the chemical spectrum from all participants using a portable GC-IMS device (Breathspec) stratified by confounding factors, such as (but not limited to) gender, age, antibiotic therapy and smoking status.
