From: Results from early programmatic implementation of Xpert MTB/RIF testing in nine countries

Bangladesh A - Direct to Xpert for all with history of previous TB treatment POC Automatic in laboratory 0-1 day Same day
B - Xpert following SS- results and TB Suggestive CXR
Cambodia Xpert following positive verbal and/or CXR screens POC Automatic in laboratory 0-1 day 0-1 day
DR Congo Xpert following SS- results Both, using a hub and spoke transport system to augment testing numbers After follow up tests and review 7-10 days 1 day
