Monitoring Quality Indicators of Truenat

Monitoring of key quality indicators or performance indicators of Truenat is important to assess the functioning of the instrument, calibration/ service requirements of the instrument, competency of the technician performing the assays and inventory management. Overall quality indicators should assess:

1. Total tests done
2. Type of samples tested
3. Test failure
4. Availability of consumables
5. Turnaround time
6. Specimen rejected
7. External Quality Assurance (EQA) results
8. Instrument downtime

Quality performance indicators should be reviewed weekly by personnel in charge of Truenat laboratory, and monthly by the Intermediate Reference Laboratory (IRL)/ National Reference Laboratory (NRL)/ Central TB Division (CTD).

Under the National Tb Elimination Programme (NTEP) the following quality indicators are to be reported monthly:

1. Total number of tests performed using Truenat (including EP-TB and private sector)
2. Total presumptive TB tested
3. Total number of presumptive DR TB tested
4. Total number of Rif indeterminate, invalid, error results
5. Total number of re-tests done and results
6. Total number of samples sent for First Line-Line Probe Assay (FL-LPA) and Second Line-Line Probe Assay (SL-LPA)
7. Total number of chips (MTB, MTB Rif) in stock
