Economics of TB Screening Simulation

Cost and yield calculations can be customised online for two scenarios
Scenario 1 Screening all members on symptoms & Digital CXR + CAD
=> only TB suspects on Xpert MTB/RIF for diagnosis
Scenario 2 All members tested directly on Xpert MTB/RIF
Assumptions on Xpert MTB/RIF are based on the March 2011 WHO publication, others are estimates or sample values and can be customised by the user. HIV can influence sensitivity and specificity levels of CXR and molecular tests. When clicking on calculate (after scrolling down) the simulation results will appear immediately.

Below you can customise all the assumptions for the simulation
