Diploma of Quality Control
|
Introduction:
Quality Control is a comprehensive course in QC terminology, practices, statistics, and troubleshooting for the clinical laboratory. Designed for those who have little or no experience with quality control but need a firm grounding, this course will help all students quickly and easily identify and correct errors in quality control procedures.
Objectives
- Introduce quality control terminology.
- Explain quality control graphical tools, including Gaussian curves, Levey-Jennings charts, CUSUM calculations, and Youden plots.
- Detail Westguard rules used to identify QC problems.
- Provide practical examples of QC in laboratory environments.
- Give suggestions for troubleshooting quality control errors.
