The definite diagnosis of tuberculosis demands that M. tuberculosis be recovered on culture media and identified using differential in vitro tests. Hence using laboratory standards is an important aspect of ensuring quality processes in all aspects of MGIT DST.
These include the following:
1. Standard laboratory biosafety measures as applicable to TB containment laboratories for handling culture isolated and performing DST
2. Trained staff to use standard operating procedures for equipment and laboratory methods
3. Standard stains for ZN microscopy, reagents and culture media as positive and negative controls
4. Using standard strains with every batch of the medium as a check on drug concentration in drug susceptibility tests
5. Using known standard positive and negative control in all biochemical tests for identification
6. Using standard Laboratory Performance Indicators for Mycobacterial Culture and DST
7. Using standard NTEP registers and formats for day-to-day work and monthly/quarterly abstracts to summarize laboratory activities
