QC abnormal results (graph)
Display Statistics (graph):
All QC results from the chosen Starrsed Control batch are shown in a chart.
Shown in the graph:
- QC results (red) = values of measurements per date
- Calculated mean (yellow) = mean value of all QC results of the specific batch
- Expected ESR (green) = Assay mean value of chosen Starrsed Control
Shown as value:
- Calculated mean = mean value of all QC results of the specific batch
- Standard deviation = the average deviation of all QC results compared with the expected ESR
- Coefficient of variation (%) = ratio of the standard deviation to the expected ESR, expressed in a percentage
- Number of QC results
This graph gives a first indication of the measuring stability of the Starrsed. Further analysis and identification of systematic errors have to be performed in the user's Quality Control System.
