QUALITY ASSURANCE

Quality is never an accident; it is always the result of high intention, sincere effort, intelligent direction and skillful execution; it represents the wise choice of many alternatives.” ~William A. Foster

Quality Assurance is the planned or systematic actions necessary to proved enough confidence that a product or service will datisfy the given requirements for quality.

Good QA system does these four things:

• establishes standard operating procedures (SOPs) for each step of the laboratory testing process, ranging from specimen handling to instrument performance validation; 
• defines administrative requirements, such as mandatory recordkeeping, data evaluation, and internal audits to monitor adherence to SOPs;
• specifies corrective actions, documentation, and the persons responsible for carrying out corrective actions when problems are identified; and
• sustains high-quality employee performance.
