Can simple sputum and urine tests catch tuberculosis earlier?
NCT ID NCT03042754
First seen Sep 16, 2026 · Last updated Sep 17, 2026 · Updated 1 time
Summary
Researchers are studying whether two tests, one on sputum and one on urine, can accurately detect tuberculosis in people suspected of having the infection. The trial enrolls 150 patients at tertiary care hospitals who can provide both sputum and urine samples. The goal is to see if these tests help diagnose TB earlier, which could lead to better treatment outcomes and stronger infection control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Xpert MTB/RIF diagnostic test and urine LAM test
- What this could lead to
- If these tests detect TB more accurately, hospitals could start treatment sooner and reduce the spread of infection.
- What could go wrong
- This is a diagnostic accuracy study, not a treatment trial. The tests may miss some cases or give false positives, and results may not apply to all hospital settings.
