Can better testing unlock the secrets of a rare lung disease?
NCT ID NCT03704207
First seen Jul 06, 2026 · Last updated Jul 07, 2026 · Updated 1 time
Summary
This study looks at how well current tests, including a simple breath test called nasal nitric oxide (nNO) testing, can diagnose Primary Ciliary Dyskinesia (PCD), a rare genetic condition that affects the lungs and sinuses. Researchers will collect and analyze data from people over age 2 who are referred for PCD testing. The goal is to see how often these tests are used and how helpful they are in making a clear diagnosis.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this study could help refine and improve the diagnostic process for PCD, leading to faster and more accurate diagnoses.
- What could go wrong
- This is an observational study, not a treatment trial, so it will not directly improve patient health. The results may not change current clinical practice if the tests prove unreliable.
