Beyond TB: could a deeper diagnostic look uncover hidden lung diseases?
NCT ID NCT06737029
First seen Aug 25, 2026 · Last updated Aug 26, 2026 · Updated 1 time
Summary
This study tests whether an enhanced diagnostic workup can identify lung diseases other than tuberculosis in patients who are about to start TB treatment based on clinical signs but have negative sputum tests. Participants will undergo a thorough review and possibly additional tests like blood work, lung function tests, CT scans, or bronchoscopy. The goal is to see if these extra investigations lead to a more accurate diagnosis at six months, potentially improving treatment and outcomes.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Enhanced diagnostic workup including detailed review, blood tests, spirometry, chest CT, repeat X-ray, sputum tests, or bronchoscopy
- What this could lead to
- If successful, this could improve diagnosis and management for patients with suspected TB, ensuring they receive the right treatment for their actual condition.
- What could go wrong
- The trial is relatively small and observational in nature, so results may not apply broadly. Additional tests may be invasive or carry risks, and the diagnostic accuracy may vary.

Who can take part
This study's own entry requirements. Only the study team can say for certain whether you qualify.
Who is studied
All adult patients who have a negative initial GeneXpert MTB/RIF test on sputum, but are about to start standard first-line treatment for suspected pulmonary tuberculosis on clinical grounds (i.e. empiric tuberculosis treatment), at four first-level Hospitals in Lusaka, Zambia. Patients will be excluded if they are inpatients (due to suspected tuberculosis), or are unable to visit the central study site for additional review or investigations.
