Objectives:
Early diagnosis of tuberculosis (TB) and multidrug-resistant TB (MDR-TB) is a priority for Viet Nam's National TB Control Programme. In many laboratories, quality systems are weak; few have attained accreditation. We implemented a structured training and mentoring program for TB laboratories and measured impact on quality.
Methods:
Six TB culture laboratories implemented the Strengthening TB Laboratory Management Towards Accreditation (TB SLMTA) program, consisting of three training workshops and on-site mentoring between workshops to support improvement projects. Periodic audits, using standardized checklists, monitored laboratories' progress toward accreditation readiness.
Results:
At baseline, all six laboratories achieved a zero-star level. At exit, five laboratories attained three stars and another one star. Overall checklist scores increased by 44.2% on average, from 29.8% to 74.0%; improvements occurred across all quality system essentials.
Conclusions:
The program led to improved quality systems. Sites should be monitored to ensure sustainability of improvements and country capacity expanded for national scaleup.

Pulmonary Tuberculosis I
Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.

Pulmonary Tuberculosis II
Here is a detailed explanation of its pathophysiology:
Transmission: The process begins when a person inhales droplet nuclei containing M. tuberculosis. These are typically released into the air when an individual with pulmonary or...

Quality Control
Quality control helps track data, visualize trends, and identify variations, making it easier to detect deviations that may affect the accuracy of an analysis. One way to do this is by generating a quality control chart, which...
