The TB STARR (Tuberculosis Screening and Tracking for Accelerated Referral and Reporting) mobile app is intended to help clinical providers, laboratory scientists, patent and proprietary medicine vendors (PPMVs), and pharmacists manage the screening, referral, and reporting of presumptive and confirmed tuberculosis patients in Nigeria. Independent clinical providers can use this app as a screening tool and as a digital register to improve TB case notification to the National TB program.
