Monitor day-to-day test variation, lot-to-lot performance of test kits, and operator variation with the Thermo Scientific™ AcroMetrix™ HCV Controls (RUO). These controls identify random or systematic errors in nucleic acid test procedures for the quantitative and qualitative determination of hepatitis C viral RNA (HCV RNA) and can assist in identifying increases in random or systematic error. The AcroMetrix HCV Controls (RUO) are not intended for use with assays used to screen the blood supply. The controls are for Research Use Only and are not for use in diagnostic procedures.
