Brief Summary:
Following a successful pilot study and a clinical assessment in healthy volunteers (ClinicalTrials.gov ID: NCT05844553) this study aims to evaluate the accuracy and precision of an Exhaled Breath Condensate (EBC) device in patients with COPD. The study will evaluate the reproducibility of 3 measurements a month apart in real breath samples. This will take place at the Clinical Research Facility (CRF) at the Royal Brompton Hospital. Real biological specimens are complex and there is the potential for losses of precision and accuracy. This can only be evaluated by comparison with established methodology. Secondly, whilst many reports can correctly classify COPD patients, there are substantial variations in absolute levels between researchers. It has been shown with artificial samples that correcting for variations in heat and mass transport can substantially reduce these variations. Collecting replicate samples from patients with COPD will allow the evaluation within this patient group.
Detailed Description:
The study aim is to recruit 15 patients with COPD and 15 healthy volunteers in order tevaluate the analytical performance of the device and the data processing and consistency of measurements over a 3-month period.
Three successive measurements will be made at monthly intervals in each patient with COPD and with each healthy volunteer requiring them to visit the Hospital on three occasions. The first visit also includes screening which will take up to 1 hour.
Firstly, each potential participant will be sent a participant information sheet.
If they decide that they wish to take part in the research study, they will be asked to come to the Clinical Research Facility (CRF) at the Royal Brompton Hospital, for screening where the research team will further explain the study to the participant. A hard copy of the participant information sheet will be provided at the appointment and participants will be encouraged to ask questions. Participants will then be presented with a consent form which they will be asked to sign before any procedures are made.
