Taking part in a proficiency testing program enables to control the accuracy of the analytical results.
BIPEA also provides accuracy monitoring charts that follow the accuracy of the results, by a graphic representation, for a given criterion and during a certain period of time.
It is a monitoring and decision tool that can rapidly highlight deviations which do not correspond to a lack of accuracy due to:
• Slow and continuous drifts (ascending or descending),
• Systematic bias,
• Matrix effect.
For an evaluator during an audit, your accuracy monitoring chart helps to quickly visualize the results of a PT and for a specific criterion, the efficiency of the corrective actions.
