Planning and Budgeting Tool for TB and drug resistant TB testing

The Global Laboratory Initiative (GLI), with its secretariat at the World Health Organization (WHO) Global TB Programme, is pleased to release a Planning and Budgeting Tool for TB and Drug Resistant TB Testing for calculation of quantities and costs of diagnostic products and laboratory supplies. The tool references product numbers and prices in the Stop TB Partnership Global Drug Facility (GDF) Diagnostics, Medical Devices, and other Health Products Catalog.

The toolkit includes a semi-automated, editable, Excel-based calculation tool and an accompanying User Guide that explains editable fields and methods for calculation of goods within each Excel worksheet. Importantly, tool calculations take country-specific epidemiology and diagnostic algorithms into account when considering each user’s diagnostic product and laboratory supply needs. Worksheets with calculation tables are included for all WHO recommended diagnostic and drug susceptibility testing methods as well as items related to biosafety, cleaning, equipment maintenance and repair.

The tool presents users with an automated annual Budget Summary that provide users with an overview of items for testing, cleaning, and biosafety as well as maintenance and repair costs. Lastly, an automated annual Laboratory Items Summary provides a list of all items to be purchased and associated total costs based on user inputs.

The Tool and User Guide are available on the GLI website and on the WHO website.

New GLI Core Group Members

28 July 2021 - The Global Laboratory Initiative (GLI) is happy to announce the election of three technical experts who joined the GLI Core Group this month: Alex Durena, Kristin Kremer and Tetsuhiro Sugamoto.

The many experiences and perspectives they bring to GLI will be of great benefit to continuing building and sustaining high-quality TB diagnostic networks and strengthening laboratory capacity at the country, regional and global level. For more information about the Core Group, please click here.

GLI core group collaborates with various partners on the development of the "Score TB Package"

26 May 2021 - GLI is pleased to announce the launch of the Score-TB package, a tool to help build quality-assured TB testing and management capacity utilizing the SLIPTA methodology. The Score TB Package combines TB test-specific Scorecards and the SLIPTA checklist in traditional and automated e-tool formats to facilitate user-friendly quality assessment of modern TB laboratories.

The Score-TB Package is intended to inform Ministry of Health officials, health facility and laboratory managers, donors, implementing partners, quality assurance personnel, programme managers and supervisory staff at national, regional and facility levels on international standards for delivering quality-assured TB testing and serve as a comprehensive, updated toolkit for quality management system assessment at individual TB laboratories.

GLI launches its Guide to TB Specimen Referral Systems and Integrated Networks

13 October 2017 - Efficient specimen referral systems contribute to optimal and timely access to TB diagnostic and treatment services. This guide provides practical information that will help developing and improving the efficiency of the specimen referral systems by establishing integrated solutions.

Targeting TB programme and laboratory managers, as well as other key stakeholders across various disease programmes, this guide presents a stepwise approach that aims at facilitating the planning and coordination of specimen referral systems, and also provides TB-specific considerations for collection, storage, packaging and transport of specimens.

GLI core group collaborates with WHO on development of Framework of indicators and targets for laboratory strengthening under the End TB Strategy

18 October 2016- The End TB Strategy calls for the early diagnosis of TB including universal drug-susceptibility testing (DST), and a prerequisite for any national TB programme to reach this goal is a quality-assured laboratory network equipped with rapid diagnostics. The newly published WHO Framework of indicators and targets for laboratory strengthening under the End TB Strategy, developed in collaboration with a team from the GLI core group, serves as a guide for all countries developing plans for laboratory strengthening during 2016-2025.

The 12 core indicators under the Framework measure programmes’ capacity to detect TB accurately and rapidly using new diagnostics, provide universal DST, and ensure the quality of testing. These indicators will be monitored globally by WHO as countries progress towards reaching the targets. The Framework also provides methods for calculating country-specific targets for the numbers of tests and facilities needed for each of the main diagnostic technologies. Given advancements in diagnostic technologies and the need for country-specific targets that consider epidemiology and issues of patient access, the previous global targets that were based on numbers of facilities relative to the general population (1 microscopy center per 100,000 population, 1 culture facility per 5 million population, etc.) are no longer recommended.

The Framework is available online at

1st Global Laboratory Initiative for Africa (GLI Africa) Country Workshop held in Uganda

Over 100 participants gathered in Kampala, Uganda, for the 1st GLI Africa Country Workshop on Strengthening TB Diagnostic Networks in Africa. The three-day workshop (19-21 July 2016) brought together representatives of National TB Control Programmes and National TB Reference Laboratories from more than 20 African countries, technical partners, multilateral agencies, donors, and other key stakeholders.

The workshop identified key priorities for strengthening TB diagnostic networks in Africa, and included discussions on improving the interface between laboratories and clinicians, building country-specific specimen referral networks, implementing new WHO policies and GLI practical guidance and tools, establishing electronic data connectivity solutions, and coordinating technical assistance. Participants also drafted the Kampala Declaration, which describes the next steps needed to strengthen TB diagnostic networks on the continent and affirms the role of GLI Africa as a partnership that can drive these steps forward.

GLI Africa was established in 2014 to support countries in the African region to achieve quality-assured, accessible and sustainable TB laboratories services. GLI Africa drives the adaptation and dissemination of global WHO policies and GLI practical guidance and tools, by coordinating technical assistance and building regional capacity to support its TB diagnostic networks.

The current Chair of GLI Africa is Amy Piatek (USAID) and the Vice-Chair is Kekeletso Kao (FIND). Core group members include Heidi Albert (FIND South Africa), Heather Alexander (CDC, current GLI chair), Affolabi Dissou (candidate SRL Benin), Yala Djamel (SRL Algeria), Jean Iragena (WHO Regional Office for Africa), Nazir Ismail (SRL South Africa), Moses Joloba (SRL Uganda), Teferi Mekonen (ASLM), Philip Onyebujoh (WHO Regional Office for Africa) and Tom Shinnick (former GLI chair). The GLI Africa secretariat function is provided by Obert Kachuwaire (ASLM). This 1st GLI Africa Country Workshop on Strengthening TB Diagnostic Networks was made possible with funding from USAID and PEPFAR.
