Abstract

There are knowledge gaps in the in-depth analysis of the most promising and robust diagnostic tool, GeneXpert MTB/RIF (CBNAAT). The cycle of threshold (CT) value of the CBNAAT test and its clinical implications has not been explored much.

The study aimed at (a) estimating the diagnostic accuracy and incremental yield of Xpert MTB/RIF in various specimens (b) establishing the association between CT value category (high, medium, low, very low) and culture time-to-positivity (TTP).

This research was supported by the UK Department for International Development’s Operational Research Capacity Building Programme led by the International Union Against TB and Lung Disease (The Union)
