The difference between quality assurance and quality control is that quality control ensures the quality of the services in terms of accuracy and precision, whereas quality assurance encompasses the overall process or activities that ensure the quality of the services provided. Simply put, QC focuses on the process output while QA focuses on the…[Read more]

What is the Levey-Jennings Chart?

The Levey-Jennings Chart is a graph used in laboratory quality control to visually indicate whether a laboratory test is working well. The chart measures the distance from the mean in standard deviations, and is interpreted using the Westgard rules. The purpose of the Levey-Jennings chart is to ensure that…[Read more]

Standards are substances in the clinical laboratory with known concentrations, purity, or quality. Similarly, controls are substances with known or determined \”range\” of values. Overall, standards and controls are reference solutions or test solutions used for assessment of the performance of an analytical procedure.

Policies, processes, and procedures are essential for an organization to run smoothly. Policies refer to guidelines that dictate how processes and procedures should be carried out. Processes refer to the steps or tasks that need to be completed to achieve an outcome, and procedures are the set of instructions for completing a process.
