Hayat Sindi co-founded Diagnostics For All (DFA) with George Whitesides, a chemistry professor at Harvard University. The organization focuses on developing affordable diagnostic devices for resource-poor settings.

DFA began developing point-of-care diagnostic tools that are inexpensive, easy to use, and do not require complex infrastructure. These tools were intended to diagnose diseases such as malaria, HIV, and tuberculosis.

DFA heavily utilized paper-based microfluidic technology, which allows for the creation of simple, disposable diagnostic devices. Paper is inexpensive and naturally absorbent, making it an ideal material for resource-limited settings.

DFA conducted pilot programs in various developing countries to test and implement their diagnostic devices. These programs provided valuable feedback and helped refine the technology.

DFA partnered with other non-profits, government agencies, and private sector companies to expand its reach and impact. These collaborations helped to scale up production and distribution of diagnostic tools.

DFA continued to innovate and improve its diagnostic devices, focusing on increasing accuracy, reducing costs, and simplifying usage. They also expanded their focus to include other diseases and health conditions.
