The United States Government–funded Tuberculosis Local Organizations Network (TBLON) Project plays a critical role in strengthening Zambia’s tuberculosis (TB) response by enhancing laboratory systems and referral networks. Through targeted technical support visits, the project supports the review and optimisation of sample transportation systems and result feedback mechanisms, ensuring timely diagnosis and linkage to care.

TBLON also promotes improved utilisation of existing diagnostic platforms and newly introduced assays, including Xpert XDR, and supports the optimised use of the urine-based LF-LAM test for immunocompromised individuals. In addition, the project strengthens laboratory quality management systems through external quality assurance activities.

These sustained efforts to improve laboratory network capacity are implemented in close collaboration with the Ministry of Health and other implementing partners.

TBLON’s support spans multiple areas, including hands-on technical mentorship to laboratory personnel to enhance diagnostic efficiency, weekly monitoring of stock levels and equipment functionality, and logistical support for the transportation of laboratory commodities for TB testing.

The project has also supported external quality assessments, supplementary procurements, and critical infrastructure investments such as solar power backup systems to mitigate the impact of load shedding.

Additional support has included the procurement of frosted slides for TB microscopy and the printing and dissemination of revised standard operating procedures for routine laboratory use. Collectively, these interventions have strengthened laboratory systems to ensure accurate, timely, and reliable test results, optimise diagnostic capacity, and sustain uninterrupted service delivery. Through these contributions, TBLON continues to support Zambia’s progress towards the global goal of ending TB by 2030.
