Could a simple mouth rinse replace invasive tests for a deadly pneumonia?
NCT ID NCT02648256
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a simple mouth rinse could help diagnose Pneumocystis pneumonia, a serious lung infection in people with weakened immune systems. Researchers used a PCR test on the rinse sample to look for the fungus, aiming to find a threshold that indicates active infection. The study involved 408 adults who needed a bronchoscopy for diagnosis, comparing the mouth rinse test to standard methods.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Polymerase Chain Reaction (PCR) on oropharyngeal rinse
- What this could lead to
- If successful, this could provide a simple, non-invasive way to diagnose Pneumocystis pneumonia quickly, potentially reducing the need for invasive bronchoscopy.
- What could go wrong
- This is a completed diagnostic study, not a treatment trial. The test may not be accurate enough to replace standard methods, and results may not apply to all patient groups.
