Quality Assurance01:19

Quality Assurance

474
Quality assurance is the overarching term used to describe the activities employed to ensure the proper performance of a system. These activities can be classified into three categories: quality control, quality assessment, and internal corrective measures. Typically, these activities work cyclically: quality control is performed before and during the analysis, while quality assessment occurs during and after the investigation. Internal corrective measures are implemented based on the findings...

Quality Control01:05

Quality Control

651
Quality control is one of the three cyclical quality assurance activities that help keep a system under statistical control. Typical quality control activities include creating quality control charts, conducting proficiency testing, and documenting and archiving results.
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...

Introduction to Statistical Process Control01:15

Introduction to Statistical Process Control

383
Statistical Process Control (SPC) is a method used to monitor and control quality within processes, particularly in manufacturing and service delivery, by employing statistical methods. SPC aims to distinguish between natural (common cause) variation and variation due to specific changes or events (special cause), allowing for timely improvements and sustained quality. The control chart, a pivotal tool in SPC, visually displays data over time alongside a central line of upper and lower control...

Control Systems

1.6K
Control systems are everywhere in contemporary society, influencing diverse applications from aerospace to automated manufacturing. These systems can be found naturally within biological processes, such as blood sugar regulation and heart rate adjustment in response to stress, as well as in man-made systems like elevators and automated vehicles. A control system is essentially a network of subsystems and processes that collaboratively convert specific inputs into desired outputs.

Quality of Water01:19

Quality of Water

349
In concrete preparation, the quality of water is paramount as it affects the strength and durability of the concrete. Potable water is usually preferred; however, it must not have excessive sodium or potassium to prevent compromising the concrete's integrity. Water quality is typically evaluated based on impurities such as dissolved solids, chlorides, and sulfates, and its pH value is ideally between 6 and 8. Even slightly acidic natural water may be acceptable unless it contains harmful...

Self-Evaluation: Self-Enhancement and Self-Verification

5.5K
Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

Area of Science:

  • Clinical Laboratory Science
  • Medical Diagnostics
  • Healthcare Quality Management

Background:

  • Effective clinical laboratory management hinges on understanding Quality Control (QC) and External Quality Assurance (EQA) principles.
  • These quality systems are crucial for minimizing patient risk and fostering continuous quality improvement within laboratory operations.

Purpose of the Study:

  • To elucidate the fundamental purposes of QC and EQA.
  • To delineate the interconnectedness between QC and EQA.
  • To highlight the expanded role of some EQA providers beyond analytical surveillance.

Main Methods:

  • This review synthesizes current knowledge on QC and EQA principles.
  • It examines the literature to illustrate the linkage between QC and EQA.
  • The review discusses the broader functions of EQA providers, including training and education.

Main Results:

  • QC and EQA are essential for identifying analytical and process errors in clinical laboratories.
  • A strong link exists between QC and EQA, with both contributing to overall laboratory quality.
  • EQA providers increasingly offer comprehensive support, extending quality improvement into pre- and post-analytical phases.
