Grand Challenges — Ultralow-Cost Diagnostics and Screening for Low-Income Countries
Funds global teams developing diagnostic devices and screening tools that cost approximately $1 per test or near-zero incremental cost per person screened for deployment in low-income countries.
This Grand Challenge is run by the Gates Foundation under its Grand Challenges grant program. It funds development of diagnostic devices and consumable test kits that amortize capital to near-zero cost per screening event or hit approximately $1 per test — a step-change below the cost of current LMIC diagnostics. Awards range from $300,000 (proof-of-concept, up to 24 months) to $1,000,000 (mature …
Ultralow-cost diagnostics for TB, HIV, malaria, STIs, maternal/newborn health, anemia, nutrition surveillance, enteric diseases, neglected tropical diseases, emerging pathogens, and diagnostic manufacturing innovations. Novel sensing modalities, software-defined diagnostics, AI-enabled and software-only approaches, and cross-sector platform technologies.
