Levey Jennings (Standard Deviation) Control Charts in Excel

Healthcare labs use the Levey Jennings charts to monitor key measures of health like cholesterol and glucose. The Levey Jennings chart, unlike other SPC charts, uses standard deviation as a way of calculating control limits.

Levey Jennings Chart

The Levey Jennings (Standard Deviation) Chart consists of :

  • A line graph of each data point
  • An average line
  • And1-2-3 standard deviation lines
  • Performs stability analysis and turns any unstable point or condition RED
  • Allows you to add data to existing control charts and create control charts with multiple (stair step) control limits

According to SOFT / AAFS FORENSIC TOXICOLOGY LABORATORY GUIDELINES 9.1.12 standard deviation may represent an unacceptably large percentage deviation from the mean. Therefore, a realistic percentage deviation should be used, such as ±20% or ±30%. This will be added to the QI Macros Levey Jennings template in July 2009.
