Number of Contacts who Received TB Diagnostic Testing

References in the content below refer to the PBMEF Guide.

Definitions

Number of contacts to a person with notified pulmonary TB with signs or symptoms of TB (e.g., presumptive TB) who received diagnostic testing for TB. Diagnostic testing includes smear, culture or a World Health Organization recommended rapid diagnostics 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.

Reporting Level
National Level indicators should be reported at the national level; data may also be reported subnationally or at the project level if national data is not available.
Reporting Frequency
This indicator should be reported on an annual basis at a minimum. More frequent monitoring on a quarterly, monthly, or weekly basis is recommended.

Data sources may include the TB register, contact investigation (CI) register, laboratory register, and electronic management information systems available at the health facility and district level.

CI is important both for active case finding and TB preventive treatment (TPT). CI identifies people recently exposed to TB with a high risk of developing TB disease or TB infection (TBI) and can help early detection and treatment and reduce the spread of TB in a community.

This indicator along with the number of presumptive bacteriologically confirmed provides a measure of the yield of Cis, allowing a calculation of the numbers needed to screen (NNS) and the number needed to test (NNT) to find a person with TB.

The number of contacts with presumptive TB who received diagnostic testing and who tested positive provides an important data point when analyzing the CI cascade.
