Listed below are the key points that have been presented.  Take time to review the material before you proceed to the final quiz.  In this online training course, you have learned to: Describe the process required to review Calibration Status The Primary Reagent and Calibration Summary windows can be used to determine if the calibration status is Valid, Invalid or Verify.                     Identify the steps required to scan Calibrator and Master Curve definition cards Calibrator definition cards are scanned in the Calibrator Definition window when the system has a Ready status.  The Scan Data button is selected and the barcode scanner is used to scan the card from the top to the bottom. The Master Curve definition card is scanned in the Master Curve Definition window when the system status is Ready or Inprocess.  From this window the Scan Data button is selected and the card is scanned from the top to the bottom.  List the steps required to schedule a Calibration Calibrations are ordered in the Worklist Schedule window.  The assay to be calibrated and the calibrator lot are selected in this window. Review Calibration Data The Worklist Summary window will display the status of the calibration that was processed.  The Calibration Evaluation Ranges window can be used to view the specific results of the Calibration Evaluation Criteria that the system used to determine the validity of the calibration. Discuss the Accept Option The accept option can be used when a calibration has a status of Verify.  Verify indicates that the calibration exceeded the observed ranges but is within the defined ranges.  The calibration can be accepted from the Calibration Data window.

Calibration Evaluation Criteria Precision Slope Ratio Deviation of low and high calibrators Calibration Evaluation Ranges window displays: Calculated calibration values Defined ranges of calibration evaluation criteria Observed ranges of calibration evaluation criteria Note: Refer to the ADVIA Centaur® XP Immunoassay System Operator's Guide for more information about the calibration evaluation criteria. . Calibration Evaluation Ranges Learn about the calibration evaluation ranges window. Base ImageHotspotsText BlocksImage FileSlope is a comparison of high and low calibrator RLUs to the Master Curve. Ratio is a comparison of low and high calibrator RLUs.The Low and High Cal Deviations are a measure of how well the high and the low calibrator RLUs fit the Master Curve.CV is the precision of the calibrator replicates based on RLUs.Defined ranges are the values for Slope, Ratio, Low Cal Deviation and High Cal Deviation you enter form the Master Curve Card when you define a Master Curve for a reagent lot.  Since these ranges are reagent lot specific, the relatively narrow limits of the ranges ensure quality calibration monitoring.Acceptable CV is the maximum CV that is acceptable for a valid calibration.After 4 calibrations for a reagent lot and calibrator lot combination, the system calculates Observed ranges for Slope, Ratio, Low Cal Deviation and High Cal Deviation. Performing new calibrations using the same reagent/calibrator lot combination, the system compares results to the defined ranges from the Master Curve definition and also the observed ranges determined by the system.  Critical Precision determines whether an outlier is too far out to automatically exclude it.
