Definitions
Number of people who screened positive with signs and symptoms of TB (i.e., presumptive TB) and who were tested with a rapid diagnostic test to confirm or exclude active TB disease during the reporting period.
Rapid diagnostic testing for active TB disease includes WHO-recommended rapid diagnostics (WRD) WHO-recommended diagnostic test (WRD): FluoroType® MTBDR (Hain), Loopamp™ MTBC detection kit (TB-LAMP), Xpert® MTB/RIF, Xpert® MTB/RIF Ultra, Truenat® MTB or MTB Plus, RealTime MTB (Abbott), BD MAX™ MDR-TB, cobas® MTB (Roche), or LF-LAM.

The data sources are basic management unit TB register, screening register, presumptive TB register, laboratory register, or electronic management information systems available at the health facility and district level.
Active case finding (ACF) or systematic screening for TB is an important tool to reach missing people with TB. It helps to reduce diagnosis and treatment delays and prevents the spread of the disease. Screening for active TB may reduce TB incidence, prevalence, and mortality; however, yield of ACF interventions varies substantially across populations.
Passive case finding, putting the burden of care seeking for TB on the patient, alone will not achieve the 90% treatment coverage target set out in many national strategic plans (NSPs) and global strategies. In high burden TB settings and among populations with poor access and uptake of TB diagnosis and care, systematic screening of people, particularly those in high risk groups (i.e. HIV positive, contacts, prisoners), at both health facility-based and community based levels are crucial.
To achieve universal access to early accurate diagnosis of TB and enhancing case finding efficiency, identification of people with presumptive TB at the first point of care and linking them to the best available diagnostic tests is essential to program management and strategy of patient centered care.
This indicator measures access to laboratory services and how many of the identified presumptive TB patients get tested for TB in a timely manner using WRD. This is about availability of testing services and accessibility by the community.
Cascade analysis of the screening and diagnosis program data will be helpful to highlight the gaps in case finding and steps to take in addressing the barriers. In addition, trend analyses will be appropriate to help the use of information.
Additional information can be collected on (1) number who submitted specimens, (2) number of specimens sent to the lab, and (3) number of results reported.
