DOTS: TB in 1,838 of the patients (12.2%) Rats: TB in 2,415 patients (16.1%) Cases detected by Rats but missed by DOTS centers (n = 577) increased TB detection by 31.4%

Notas do Editor
- Limiting factor is lab technicians preparing samples - presenting prepared slides for second-line screening - presenting samples that have not been autoclaved
- The need for know reinforcer samples. Reinforcement ratio is important. Possible 1 indication > confirmation by led microscopy > use as reinforcer sample for consequent rats To determine how many reinforcement samples are needed to sustain accurate performance To determine how many samples a single rat can evaluate without reinforcement before its accuracy declines. To determine how frequently a given rat can evaluate samples without reinforcement before its accuracy declines. To determine the number of samples a single rat must evaluate to provide sufficient reinforcement samples for other rats at different TB prevalence levels. To determine whether evaluation by a second rat, rather than by LED microscopy, can be used to verify samples as positive.
