Levy Jenning Chart ((link))

The Levy-Jennings chart isn’t just about passing inspections. It’s your early warning system. Catching a shift before it produces a falsely low troponin or falsely high potassium can directly save a life. When you respect the L-J chart, you protect every patient whose sample runs through your lab.

Using LJ charts is essential for patient safety . They allow technicians to catch "drifts" (slow changes over time, often from reagent aging) and "shifts" (sudden changes, often from new lot numbers or lamp changes) before they affect patient diagnoses. Modern analyzers often automate this process using QC modules , but understanding the manual logic remains a core competency for laboratory scientists. levy jenning chart

The Levey-Jennings chart is widely used in laboratory medicine to monitor and control the quality of laboratory test results. It is commonly used in: When you respect the L-J chart, you protect
