• Considers all components within a system
• Identifies the connection and relationship (e.g., cause and effect) among the components

Definition of A Lab Quality SystemDefinition of A Lab Quality System
The organizational structure, responsibilities, processes, procedures, and resources for implementing quality management of the laboratory or testing site.
In other words… all activities which contribute to quality of tests, directly or indirectly.

Why is Quality System Important to HIV Rapid Testing? Why is Quality System Important to HIV Rapid Testing? • Ensures that quality is the foundation of
everything we do • Sets the standard for level of quality • Meets/exceeds customer expectations• Provides means to prevent, detect and correct
problems • Becomes the core of a monitoring, evaluation, &
improvement system• Reduces costs
Even the simplest Rapid Test is not foolproof
