GLI TB Microscopy Network Accreditation: an Assessment Tool

Although there are many international guidelines and technical materials for procedures and EQA, there is little or no external validation to assure that countries are adequately managing the microscopy networks. This accreditation tool is based on the many WHO-approved guidelines that provide technical direction, recommendations and specific forms to document and monitor performance of microscopy networks. The tool is composed of eleven standards with each a corresponding measure defining the minimum allowable performance to achieve accreditation.
