Breath test study for allergic rhinitis and asthma
Part of Immune system & allergy, Lungs & breathing clinical trials.
This study is looking at certain substances in your breath to better understand allergic rhinitis, asthma, and the combination of both (CARAS). It could help doctors find new ways to diagnose or treat these conditions.
Summary written for real people, not researchers, by Clin2.

This trial tests a traditional Chinese medicine formula combined with acupressure patches to help patients with combined allergic rhinitis and asthma during periods when symptoms are calm. The study checks whether this treatment is safe and effective for people with a specific pattern called 'yang-deficiency syndrome.'
This study looks at chronic rhinitis (long-term stuffy or runny nose) in Chinese adults. It aims to understand how common it is and what causes it.
This study uses a nasal allergen provocation test to help diagnose chronic rhinitis more accurately. If you have allergic rhinitis or are a healthy volunteer, you may help researchers learn how well this test works.
This study tests a nasal spray (CDA) to see if it can help diagnose irritant-induced rhinitis, a type of chronic stuffy/runny nose not caused by allergies. It compares people with this condition to healthy volunteers.
This study looks at how traditional Chinese medicine affects people with asthma. It may help researchers understand what treatments work best for different patients.
This study looks at the substances in nasal fluids from people with chronic rhinitis to better understand the condition and find new ways to diagnose it. You provide a free sample and answer some questions.
