OTHER_PRE_SPECIFIED outcome

Timeframe: 12 week post treatment

Population: Only 22 had both Xpert and plasma samples collected. Some participants had \>1 paired sample. HCV RNA from plasma was compared to the Xpert result. Sensitivity is number of positive Xpert results divided by the number of positive plasma results. The specificity is number of negative Xpert results divided by the number of negative plasma results.

To determine the sensitivity and specificity of the Xpert® HCV Viral Load assay for HCV RNA detection in samples collected by finger-stick capillary whole-blood.
