Chest X-ray AI + Pooled Molecular Testing (Union 2025)
Union World Conference on Lung Health 2025 · Copenhagen · Jul 2024 – Mar 2025 · presented Nov 2025
Demonstrated that combining AI-scored digital chest X-ray triage with sputum pooling extends molecular TB diagnostics into resource-limited community settings — with materially lower per-case cost.
Highlights
- 2,183 specimens processed under the AI-score-guided pooled testing workflow.
- 45% reduction in Xpert / Truenat cartridge consumption.
- 0.55 tests per person screened — more than halving the test-per-person rate.
- E-Poster EP10-793-19, Track K2 TB diagnostics, Enhanced TB detection session, Copenhagen, 19 November 2025.
