Summary

This completed study looked at whether substances in nasal fluid can help doctors objectively measure the severity of respiratory conditions like asthma, COPD, hayfever, and sinusitis. Researchers collected samples from 111 adults (including healthy volunteers) using a small nasal sampling device. The goal was to find a simple, non-invasive way to assess disease severity and quality of life, rather than relying only on symptoms or breathing tests.
