title: A quality control system and its application to clinical chemistry.
abstract: A quality control system is presented that involves the Quality Control Log for documenting data, decisions, and corrective actions. It emphasizes the use of the Calibration Work Record, cusum, and comparison of means to monitor acute and chronic drift and method bias. It introduces clinically useful limits criteria for efficient and cost-effective quality control.
