This trial is testing a streamlined version of the nasal allergen provocation test (NAPT), a procedure that applies allergens directly to the nasal lining to help doctors diagnose chronic rhinitis more accurately. Currently, diagnosing nasal inflammation is confusing because some patients have allergic symptoms without positive allergy tests, while others test positive but don't seem allergic. This study aims to develop a faster, simpler version of the test so it can be used more widely in everyday medical practice.
Chronic nasal inflammation affects hundreds of millions of people worldwide and significantly impacts daily life, sleep, and work. However, doctors often struggle to correctly identify what's causing each person's symptoms because current diagnostic methods are inadequate, leading to ineffective treatment. This trial exists to create a better, quicker diagnostic tool that will help doctors match patients with the right treatment the first time.

You will visit the hospital's ear, nose, and throat department for one appointment. The room will be kept at a comfortable temperature, and you'll have 15–30 minutes to adjust. The staff will first measure your baseline nasal airflow and ask you about your symptoms using a simple scale. Then they will apply a test substance to your nasal lining and watch for any reaction over 15 minutes. If needed, they will apply allergens at gradually increasing concentrations, each time waiting 15 minutes to see if your symptoms develop. If you have a reaction, the test stops immediately. The staff will collect a small nasal sample and reassess your symptoms before you go home.
