From: Traceability, reproducibility and clinical evaluation of Sansure Realtime HCV RNA assay
Bland-Altman analysis of hepatitis C virus (HCV) RNA level were measured with Sansure HCV and CAP/CTM HCV assays in total 215 clinical plasma samples (a) and HCV-1b samples (b) with detectable HCV RNA. The difference between the Sansure and CAP/CTM measurements was plotted according to the mean of the two values. Area between two dashed lines corresponded to mean difference ±1.96 SD
