Evaluation of Nasal Biomarkers for Objective Assessment of Disease Severity in Respiratory Disorders
This research study is an observational, single site study quantifying expression of biomarkers of respiratory disease in nasal fluid using the ABEL microsampler device. The primary objective of this study is to compare biomarker expression between healthy controls and participants with respiratory disorders such as chronic obstructive pulmonary disorder (COPD), hayfever, chronic sinusitis, asthma and rhinitis.
• All participants:
• 18 years of age or older
• The participant must be able to comprehend and sign an approved Informed Consent Form and other applicable study documents.
• Healthy volunteers:
• No significant sinonasal/pulmonary symptoms or prior diagnoses of sinonasal/pulmonary conditions as determined by pre-enrolment questionnaires.
• Case goup:
• Participants must be previously diagnosed with rhinitis, chronic sinusitis, asthma, or COPD by a medical professional.
