Quality Management
A stepwise approach for TB laboratories
The GLI Quality Tool is built on a structured quality management framework designed specifically for tuberculosis laboratories. It guides users through a phased implementation model grounded in twelve internationally recognized Quality Systems Essentials.
The Twelve Quality Systems Essentials
Every phase of the GLI Quality Tool is organized around the same twelve essentials, linking the tool to international laboratory quality frameworks. These essentials form the backbone of a comprehensive quality management system:
- Facilities & Safety
- Organization
- Personnel
- Equipment
- Purchasing & Inventory
- Process Management
- Information Management
- Documents and Records
- Customer Focus
- Assessment
- Nonconforming Event Management
- Continual Improvement
The GLI Quality Tool was developed through an international collaborative effort, bringing together expertise from global health organizations and laboratory specialists dedicated to strengthening tuberculosis diagnostic services. The tool represents a consensus-based approach, refined through input from partners across multiple countries and institutions. Its design reflects a practical understanding of the realities laboratories face, particularly in settings where resources are limited and competing priorities demand careful planning. By grounding the framework in internationally recognized quality systems standards, the tool provides a credible and defensible pathway for laboratories seeking to improve their operations while aligning with broader national and global laboratory strengthening initiatives.
The four-phase implementation model at the heart of the tool allows laboratories to progress at their own pace, building confidence and capability before advancing to more complex quality activities. Each phase builds naturally on the previous one, ensuring that foundational elements such as documentation, safety, and personnel training are firmly established before moving toward more advanced systems like internal assessment and continual improvement planning. This stepwise structure also makes it easier for laboratory managers to secure buy-in from staff and leadership, since progress can be demonstrated incrementally with visible results at each stage, rather than waiting for a distant, abstract goal.
The twelve Quality Systems Essentials cover the complete spectrum of laboratory operations, from organizational structure and personnel management to equipment maintenance, purchasing, and inventory control. Also addressed are customer focus, document and record control, assessment processes, and the management of nonconforming events. This comprehensive coverage ensures that no critical area is overlooked during implementation. The essentials are presented in accessible language with practical checklists and guides, making them usable by laboratory staff at all levels of experience. The framework encourages systematic thinking about how different parts of the laboratory interconnect and how quality practices in one area can reinforce improvements in another.
Beyond the core framework, the tool includes supporting resources such as user instructions, downloadable checklists, and feedback mechanisms that help laboratories track their own progress over time. The renewed and optimized version reflects lessons learned from field implementation, incorporating adjustments based on real-world experience and user input. Laboratories can use the tool to create tailored roadmaps for quality improvement, aligning their activities with national strategic plans and international accreditation requirements. Ultimately, the GLI Quality Tool serves as a scaffold for sustainable quality culture, helping tuberculosis laboratories move from basic compliance toward a genuine, embedded commitment to quality that benefits patients, staff, and the broader health system alike.
