Patient sputum samples ready for analysis

Smear microscopy testing of sputum samples — a DOTS-recommended diagnostic method — improved case detection in the Orel district from 40% to 55% in a five year period. This is well above the national average of 30% in 2004. The method detects TB cases at an early stage, when patients are relatively healthy. It is complemented by x-ray testing.
