The AccuPlex™ SARS-CoV-2, Flu A/B and RSV Verification Panel is formulated for use with multiplex test methods that can detect SARS-CoV-2, flu A/B and respiratory syncytial virus (RSV). Included are three different concentrations of positive reference material as well as negative reference material directed against the human RNase P gene. The panel is optimized for assay verification at installation by documenting test performance along the assay’s range enabling laboratories to establish lower limits of detection, perform assay comparisons, and evaluate staff proficiency. Product is released using the US CDC Influenza SARS-CoV-2 (Flu-SC2) Multiplex Assay and Cepheid GeneXpert® Xpress SARS-CoV-2 and Flu/RSV Assays.
