  1. *The NRL was initiated in 2003 and organization of the network began in 2004. The lab network was able to begin reporting number of specimens by 2005. We attribute the gradual decrease from 13.7% to 6.5% to comprehensive training of laboratory technicians and to the national TB program in its goals for reducing spread of TB.
