This journal recently reported a survey of statistical quality control (SQC) practices in a group of academic medical centers.1 The 21 laboratories represented “highly regarded academic institutions comprising the entirety of the US News & World Report 2016 to 2017 honor roll list.”1The laboratories utilized a wide variety of instrument systems for routine chemistry and immunochemistry testing, thus their SQC practices should be representative of the best practices in US laboratories today. They allow more accurate distinguishing of random from systematic causes of fluctuations in the value of a mark of quality, i.e. They must emphasize statistics rather than application. use quality control, measurable attributes and specifications must be developed against which the actual attributes of the product or service can be compared. First, whereas SPC measures the independent variables called process inputs, SQC looks at the dependent process outputs. This book provides an accessible presentation of concepts from probability theory, statistical methods, the design of experiments and statistical quality control.

If there are out-of-control points, you may want to try and find out what caused them. Statistical quality control (SQC) is the application of statistical methods for the purpose of determining if a given component of production (input) is within acceptable statistical limits and if there is some result of production (output]. Some people talk about statistical process control and statistical quality control (SQC) interchangeably. However, in some cases, this will be difficult. This method is used primarily for manufacturing lines rather than chemical processing equipment, though it is valid for both.
