Levey-Jennings Chart is used to plot which data set?

• A. Controls
• B. Patient Results
• C. Calibration Curves
• D. Instrument Logs

Answer: (A)

The main idea is that Levey-Jennings charts are quality control tools used to monitor assay performance over time by plotting control material results. These charts track how close the control data stay to the expected mean and within acceptable limits (often set in standard deviation units), making it easier to spot trends, shifts, or out-of-control events that suggest issues with the method, reagents, or instrument. They are not used for patient test results, calibration curves, or instrument maintenance logs. So the data set plotted on a Levey-Jennings chart are the control results.
