Improving chronic rhinitis diagnosis with a nasal allergy test
Part of Ear, nose & throat clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 75 years old.
- You have allergic rhinitis (AR) or are a healthy volunteer with no nasal symptoms and negative allergy tests.
- You are willing to have a nasal provocation test and provide samples for free.
- You are not currently taking any allergy medications (like antihistamines, nasal sprays, or steroids).
- You do not have other serious conditions like severe asthma, COPD, cancer, autoimmune disease, or a recent infection.
- You are not pregnant, breastfeeding, or planning to become pregnant, and have not had a nasal surgery in the last 2 months.

This study looks at the fluids from your nose to find unique markers that might help diagnose chronic rhinitis more accurately. By studying your nasal secretions, researchers hope to understand the condition better and develop better tests.
This study is testing a new nasal spray challenge, called the CDA nasal provocation test, to help doctors safely and accurately diagnose a condition called irritable rhinitis (IR). If you have long-term nasal symptoms but no allergies, this test could help confirm the cause and guide better treatment.
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 trial compares two methods of a procedure that targets nasal nerves to reduce chronic rhinitis symptoms. It may help people whose rhinitis is not caused by allergies.
This trial is studying the bacteria in your nose and mouth during treatment with an allergy spray placed under your tongue. The goal is to understand how this treatment affects your allergy symptoms and your body's natural defenses.
This trial tests a treatment called washed microbiota transplantation, which transfers gut bacteria from healthy donors to people with allergic rhinitis. The goal is to see if changing the gut bacteria can reduce allergy symptoms like sneezing, itching, and a runny or blocked nose.
