PURPOSE:
The right quality control (QC) approach can detect and prevent errors. In this activity, participants learn the importance of establishing acceptable ranges for control material and the importance of control rule selection in interpreting changes in the analytical system.
KEY MESSAGES:
- Each laboratory must establish acceptable ranges for their control material based upon the calculated mean and SD.
- It is important to use the calculated mean and SD on the QC chart to apply QC rules and strategy.
- The selection of QC rules will influence the probability of detecting significant changes in the system.
SELF ASSESSMENT:
Can you:
- Recognize the importance of establishing QC ranges specific to their instrument?
- Plot QC data onto a Levey-Jennings Chart?
- Recognize how graphical charts are easier to interpret and assess the method’s stability?
- Recognize the role QC rule selection plays in interpreting control results?
