Development of the PanDx Integrated Diagnostic Platform

Wallace White
Director, Point-of-Care Diagnostics
Stratos Product Development

UC Berkeley, March 5, 2015

After a decade developing point-of-care diagnostics for commercial clients, Stratos Product Development was approached by the Bill and Melinda Gates Foundation for a bigger challenge: creating a single system capable of all the diagnostics needed at primary health clinics in developing countries. In this—the first public talk on the project—Wallace White will describe the development of the PanDx system and share observations from the health-clinic visits on three continents that have informed it.

Video of the talk is available on YouTube: https://www.youtube.com/watch?v=9oewE5NH4mI

  15. 15. 15 Can you create a new device that quickly diagnoses HIV, TB, malaria, and other diseases… accepts different samples, like blood, saliva, and sputum… is affordable… and reliable… and will work in a small clinic that has only a few hours of electricity a day? http://www.gatesnotes.com/About-Bill-Gates/Why-Our-Foundation-Takes-On-Grand-Challenges
  16. 16. 16 Today, five public-private partnerships have taken up the challenge. The journey from idea to reality is a long one. For one thing, the partners had to figure out whether making such a machine was even technically feasible. It is—several of them have working prototypes. http://www.gatesnotes.com/About-Bill-Gates/Why-Our-Foundation-Takes-On-Grand-Challenges

  66. 66. 66 Lessons from William Foege “We learned the need for OPTIMISM. The trouble with being an optimist, of course, is that people think you don’t know what’s going on. But it is the way to live. I tell students there is a place for cynicism and a place for pessimism and whenever you need it, contract for it but don’t get those people on your payroll. They will ruin your day. We were an optimistic group.”
