Overview

Quality control (QC) is one of the most important impacts on laboratory testing. It ensures both precision and accuracy of patient sample results.

Effective quality control help correct flaws in the analytical processes of a lab before potentially incorrect patient results are released.

This course focuses on providing a systematic, process-oriented approach to meeting quality objectives, and delivering consistent, high-quality, cost-effective laboratory services through the implementation of QC.

What I will learn?

By the end of this course, the candidates will be able to:
- Define and apply the basic elements of quality control and implement quality control program in the laboratory.
- Define, calculate and apply the following statistics :
Mean, standard deviation, coefficient of variation, coefficient of variation ratio and standard deviation
- Describe, choose and apply each of the Westgard rules
- Identify which Westgard rules identify random errors and which rules identify systematic error
- Identify and differentiate trend and shift
- Identify and differentiate random errors and systematic errors
