A new reagent from the same lot was placed on an instrument, which caused both levels of QC to be quantified as unacceptably high. Both QCs were reanalyzed and remained unacceptably high. Which of the following troubleshooting scenarios does not fully address this issue? Please select the single best answer A different reagent pack from the same lot was placed on the analyzer, and both reanalyzed levels of QC returned results within the expected quantitation The new reagent pack was recalibrated, and both reanalyzed levels of QC returned results within the expected quantitation A different reagent pack from a different lot was placed on the analyzer and recalibrated. Upon completion of recalibration of the new reagent pack, both re-analyzed levels of QC returned results within the expected quantitation New QC levels were placed on the analyzer and were reanalyzed several more times until they returned results within the expected quantitation
