Abstract:

Diagnostic laboratories are increasingly required to meet stringent quality standards, and validated assays are needed to achieve formal accreditation. Validation of test methods is often considered to be finalised when the assay parameters and characteristics have been established. However, like any process, diagnostic assays are subject to random variation resulting in shifts in the mean test values. Continuous monitoring of assays using control charts will alert the interpreter of changes in performance. For this purpose, several charting methods have been developed and implemented. This…
