In quality control, a shift refers to a sudden, noticeable change in the process or product output, typically caused by a specific event or factor. A trend, on the other hand, is a gradual change over time in the process or product output, indicating a consistent direction of improvement or deterioration. Monitoring shifts helps identify immediate issues, while monitoring trends helps predict long-term performance.

BeauA shift is when the QC values move suddenly upward or downward from the mean and continue the same way mathematically changing the mean. This is usually seen when new reagents or quality control material has been used, when there is an issue with the instrument such as a change in internal temperature or dirty cuvettes, or when a calibration was not accurate.
A trend is when the QC values slowly move up or down from the mean and continue moving the same direction over time. This can be the case of a calibration that is failing or reagent stability issues.
