Laboratory quality control. Laboratory quality control is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results, in order to improve the quality of the results reported by the laboratory. Quality control (QC) is a measure of precision, or how well the ...
The Westgard rules are a set of statistical patterns, each being unlikely to occur by random variability, thereby raising a suspicion of faulty accuracy or precision of the measurement system. They are used for laboratory quality control, in "runs" consisting of measurements of multiple samples. They are a set of modified Western Electric rules ...
Calibration, quality control, and proficiency testing materials; Test system troubleshooting and equipment maintenance; Interpretation and judgment; Centers for Medicare and Medicaid Services (CMS) has the primary responsibility for the operation of the CLIA Program. Within CMS, the program is implemented by the Center for Medicaid and State ...
ISO 15189 Medical laboratories — Requirements for quality and competence is an international standard that specifies the quality management system requirements particular to medical laboratories. The standard was developed by the International Organisation for Standardization 's Technical Committee 212 (ISO/TC 212).
Analytical quality control. Analytical quality control ( AQC) refers to all those processes and procedures designed to ensure that the results of laboratory analysis are consistent, comparable, accurate and within specified limits of precision. [1] Constituents submitted to the analytical laboratory must be accurately described to avoid faulty ...
The Principles of Good Laboratory Practice (GLP) establish rules and criteria for a quality system that oversees the organizational processes and conditions in which non-clinical health and environmental safety studies are planned, conducted, monitored, recorded, reported, and archived.
Verification is intended to check that a product, service, or system meets a set of design specifications. [6] [7] In the development phase, verification procedures involve performing special tests to model or simulate a portion, or the entirety, of a product, service, or system, then performing a review or analysis of the modeling results.
There are different definitions within laboratory quality control, wherein "analytical sensitivity" is defined as the smallest amount of substance in a sample that can accurately be measured by an assay (synonymously to detection limit), and "analytical specificity" is defined as the ability of an assay to measure one particular organism or ...
