Table 2– Methods used to estimate the number of laboratories required, as per targets and indicators of the Global Plan to Stop TB 2006–2015
AssumptionsOne AFB microscopy laboratory per 100 000 population; one culture laboratory per 5 000 000 population; one DST laboratory per 5 000 000 population
DescriptionBaseline number of laboratories per country was obtained from the WHO’s global TB database
This number was compared with the target number set out in the global plan
The difference is the number of laboratories that require new laboratory equipment for any of the three diagnostic methods Capital investment for laboratories refers only to equipment, infrastructure is not included
  • AFB: acid-fast bacilli; DST: drug susceptibility testing.
