Although quality control directives explain how to conduct an analysis, they do not indicate whether the system is under statistical control. This is the role of quality assessment, the second component of a quality assurance program.

The prescriptive approach involves a strict protocol for quality assessment, often required by regulatory agencies, while the performance-based approach allows laboratories flexibility, using control charts to monitor statistical control. Control charts help detect errors, ensuring precision and accuracy in analysis.

There are two general approaches to developing a quality assurance program: a prescriptive approach, in which we prescribe an exact method of quality assessment, and a performance-based approach in which we can use any form of quality assessment, provided that we can demonstrate an acceptable level of statistical control.

Quality assessment helps maintain, detect, and suggest solutions for loss of statistical control. It includes internal methods, like analyzing duplicate samples and spikes, and external methods, such as laboratory certification by an agency.

Good laboratory practices (GLPs) outline general operations such as data recording, reagent preparation, and equipment maintenance. Good measurement practices (GMPs) focus on equipment use and calibration specific to techniques. Standard operations procedures (SOPs) provide detailed instructions for analyzing specific analytes.

It distinguishes between quality control, which involves bringing a system into statistical control through documentation and good practices, and quality assessment, which uses statistical tools to evaluate whether an analysis is under control and identify potential issues.
