LEVEY-JENNINGS QC CHART

The Levey-Jennings QC chart is a graphical representation tool used in quality control testing to monitor and analyze the quality of analytical measurements over time. It plots the measured values of a QC material against their respective time of analysis, with the central line representing the mean and the upper and lower control limits representing the acceptable range of variation.

By visually identifying any deviations or trends that fall outside the acceptable range of variation, the Levey-Jennings QC chart helps analysts to detect issues with the analytical process before they become significant enough to affect patient care or other outcomes. As such, it is an essential tool for quality control testing in clinical laboratories, research laboratories, and other analytical settings. Overall, the Levey-Jennings QC chart is an efficient way to ensure the quality of analytical measurements and maintain the accuracy of laboratory results.
