This chapter is concerned with two aspects of laboratory quality control, viz., control charting, which is a form of internal quality control, and proficiency testing, the analytical report. The most important tool in this quality control is the use of control charts. The basis is that the laboratory runs control samples together with Results 18 - 81 Monitoring performance indicators through control charts enables the identification of trends. The laboratory can then address analytical To achieve and demonstrate analytical method stability, modern laboratory QA programs rely on control charts. These charts tell us whether the analytical You have started a control chart on a certain product parameter. This parameter is determined by a lab test method. Suppose the test result gives a point that is

The use of control charts in the analytical laboratory is introduced. Examples are provided to illustrate the use of control charts in assessing the performance of a measurement system; these are followed by a discussion of the assumptions and theory underlying the charts and of rules that are used to signal measur Whereas the term “quality assurance” (QA) involves the overall measures taken by the laboratory to regulate quality, “quality control” (QC) relates to the individual measurements of samples. The two aspects of QC concern internal quality control, the subject of this chapter, and proficiency testing, which is a form of the external QC Use of Control Charts in Analytical Laboratory 2.1 INTRODUCTION. This chapter is concerned with two aspects of laboratory quality control, viz., control charting, which is a form of internal quality control, and proficiency testing, which is a form of external quality control. The main focus is on control charts, as they are the simplest and cheapest method for obtaining assurance that the laboratory's analytical systems are well-behaved
Laboratory quality control (QC) is designed to detect, reduce, and correct deficiencies in a laboratory's internal analytical process prior to the release of patient results. the use of Shewhart's individuals control chart in the clinical laboratory.
