DARE-TB has been designed to address critical evidence gaps on the diagnostic performance and operational value of near point-of-care (NPOC) nucleic acid amplification tests (NAATs) within community-based case finding (CBCF) strategies. Although World Health Organization (WHO) recommends wider access to molecular testing, its use remains concentrated in facility-based settings well short of the global targets and largely dependent on sputum production. This creates a substantial diagnostic gap for people reached through community screening who either cannot provide sputum or whose sputum specimens cannot be tested on a NAAT at a facility, particularly for marginalized, hard-to-reach populations with poor access to healthcare.

Primary Endpoint: Diagnostic accuracy (sensitivity, specificity, PPV, NPV) of NPOC assays (tongue swab and sputum swab) compared against the microbiological reference standard (MRS: sputum culture).
Timeframe: The overall duration of the DARE-TB Study is expected to be 12 months, beginning in Q2 2026 and concluding in Q2 2027. Recruitment, diagnostic testing, and follow-up will all occur between Q2 2026 and Q1 2027
