In the annual global burden of 8.6 million TB cases, India accounted for 20%. In the last two quarters of the year 2012, the RNTCP cell at Dharmapuri Medical College had recorded a twofold increase in slide positivity rate with use of LED microscope, which was more than the peripheral designated microscopic centers (DMC). This study was planned to increase the efficiency of the DMCs by early detection and intiation of ATT (Anti tuberculous therapy) in new cases , to recheck them for quality assurance and thereby increase the access of RNTCP service to periphery areas. Early morning sputum samples from 488 suspected cases of tuberculosis were collected from the DMCs in the three Tuberculin Units. The smears were screened only by ZN staining at the DMCs ,but screened simultaneously by ZN staining and LED at the RNTCP cell in the tertiary care centre. The present study showed smear positivity by both methods was nearly the same. The false negativity was considerably lower by 1% in LED when compared with ZN microscopy.  The objective to assess the performance of laboratory at the DMC was done and was satisfactory. 6 new cases missed at the DMC were picked up by LED at RNTCP Cell and after confirmation, treatment was initiated without delay. In the present study (21 / 488)4% of the sample size  were children (0-11yr) age group. Hence the present study highlighted  the need to identify the incidence of pediatric TB in our local population and suggested further research.

Keywords: ATT (Anti tuberculous therapy),designated microscopic centers (DMC).
