The Planning and Budgeting Tool for TB and Drug Resistant TB Testing facilitates systematic calculation of the quantities and costs of products for countries planning to order diagnostic products and laboratory supplies from the Global Drug Facility Catalog. The tool calculates the quantities of products required using each setting’s past consumption, or a morbidity-based forecasting method for all WHO recommended TB diagnostic products. It can also take into consideration targets for scaling up testing services according to the country’s epidemiology and their diagnostic algorithms.

The product prices, article numbers and descriptions used in the tool are from the 2024 GDF Diagnostics Catalogue. The tool comprises a semi-automated, Excel Tool and a User Guide. Excel Tool tables are included for all WHO recommended diagnostic testing methods as well as items related to biosafety, cleaning, equipment maintenance and repair with reference to GDF article numbers and prices.

The tool is an updated version of a forecasting tool used in the EXPAND-TB project, developed by the Foundation for Innovative New Diagnostics (FIND), the Global Laboratory Initiative, the Global Drug Facility, and partners.
