Performance of the Xpert HBV Viral Load assay versus the Aptima Quant assay for quantifying hepatitis B virus DNA.

Quantification of HBV DNA is used for initiating and monitoring antiviral treatment. We have evaluated the Xpert HBV Viral Load (VL) assay on the GeneXpert instrument. We estimated its limit of detection to be 7.

Analytical performance of the VERIS MDx system HCV assay for detecting and quantifying HCV RNA.

Background: The diagnosis of HCV relies on the detection of viral RNA.

Objective: To evaluate the performance of the VERIS/MDx System HCV Assay, a new automated system for quantifying HCV RNA, and to compare with the COBAS Ampliprep/COBAS Taqman™ (CAPCTM) HCV Test version 2.0.
