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 ...
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 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 ...
The OECD Principles of Good Laboratory Practice (GLP) cover the testing of chemicals or chemical products in non-clinical settings, either in laboratory conditions or environmental settings, such as greenhouses and field experiments. These principles exclude studies involving human subjects.
Jeremy Gruber, Council for Responsible Genetics In the US, newborn screening (NBS) is mandated in all states, though parents may decline the screening process based on religious beliefs or philosophical reasons in some states. Few parents opt of the program due to health concerns, and a lack of awareness of the ability to opt-out. After the initial testing is complete, the residual dried blood ...
Individualized Quality Control Plan. The Individualized Quality Control Plan ( IQCP) is a quality management system under the US Clinical Laboratory Improvement Amendments (CLIA) federal regulatory standards. It is designed to enable regulated medical laboratories to manage the frequency of their quality control.
External quality assessment (' EQA), or external quality assessment schemes ( EQAS) is a challenge of the effectiveness of a laboratory's quality management system, typically referring specifically to medical laboratories. The term external refers to the fact that that the laboratory's results are assessed by a third party.
Measurement system analysis. A measurement system analysis ( MSA) is a thorough assessment of a measurement process, and typically includes a specially designed experiment that seeks to identify the components of variation in that measurement process. Just as processes that produce a product may vary, the process of obtaining measurements and ...
