Under the National Tuberculosis Elimination Program (NTEP) network, the most peripheral laboratories are the Designated Microscopy Centres (DMC) which serve a population of around 100,000 each (50,000 population norm in tribal and hilly areas). 

 

The basic requirements for microscopy centres include (Figure):

  1. Good ventilation by exhaust fan and open windows
  2. A table/ work bench to prepare smears
  3. A sink to stain smears
  4. A table/ bench to examine smears
  5. A table/ bench for documentation
  6. Basin for hand washing with supply of water
  7. Good lighting
  8. Non-slip flooring
  9. Sample receiving area

Laboratory Diagnosis of Tuberculosis by Sputum Microscopy
ESTABLISHMENT PROVISIONS UNDER NTEP FOR DMC FACILITIES 
Infrastructure development Normative amount as per “Norms and basis of costing” for NTEP. Unit cost for initial establishment/ refurbishment/ upgradation/ maintenance of civil work to be carried out as per rates prescribed by Public Works Department (PWD) or cell/ division/ corporation/ wing for infrastructure development
Human resources NTEP trained Lab Technician (LT)
Diagnosis
  • Provision for sputum collection in the presence or absence of an LT
  • Adequate space for storing and using binocular microscope, essential lab consumables, space for recording and reporting
  • Availability of running water
  • Availability of electricity
  • Availability of biomedical waste management facilities
Equipment Binocular microscope with a light source
Location of DMC Ideally, the DMC should be located in a peripheral health facility that has at least 50 new adult OPD/day.
