The system presents Quality Control (QC) data in both a summary format and in a chart format. It applies Westgard QC rules to the data to help determine assay and system QC samples when your laboratory protocol indicates that Control material should be analyzed. Beckman Coulter recommends a daily analysis of at least two levels of Control materials. You should also run controls with each new calibration with each new lot of reagents after specific maintenance or Troubleshooting laboratory should determine its own Control frequency based on the CLSI (formerly NCCLS) Guideline C24-A3 STATISTICAL Quality Control FOR QUANTITATIVE MEASUREMENT flag DeterminationThe DxC uses the Z-score method to standardize the scale of a normally distributed measurement variable.
