LJ quality control graphs, or Levey-Jennings charts, are statistical tools used in laboratory settings to monitor the performance of assays over time. They plot the results of quality control samples against time, allowing for the visualization of trends, shifts, and outliers in data. The chart typically includes control limits set at ±1, ±2, and ±3 standard deviations from the mean, helping laboratories assess whether their processes are in control and consistent. This tool is essential for ensuring accuracy and reliability in diagnostic testing.
