Widespread Testing for COVID-19

Worldwide, individuals and organizations are working together to supply accurate and accessible COVID-19 testing. Support and follow these projects that are coordinating widespread testing efforts. If you are part of or would like to suggest other projects contributing to widespread testing please add those to the Team Earth map here.

Widespread testing

is an effective way to identify asymptomatic carriers, stop contagions from spreading, and allow people to safely return to work and social interaction. One of the most efficient ways to implement widespread testing is by group testing, or batch testing, via ddPCR. Using a highly sensitive test on groups of people that live or work together, we can identify early and asymptomatic carriers on an ongoing basis while conserving scarce testing resources.


The processes causing bottlenecks in testing can be aided by professional scientists available to help with reagent sourcing, testing personnel, and testing validation. As these processes are refined, it’s essential that the average person has access to accurate and timely information about where to get tested, driven by publicly available data. Projects included here are examples of critical components of an effective widespread testing strategy.

Individual Projects

Highly-Sensitive ddPCR group testing involves testing up to 1200 individuals in two-phase tests. The strategy uses Droplet Digital Polymerase Chain Reaction (ddPCR) for pooling samples.

Our database of U.S. testing centers provides a consolidated map of nationwide testing centers, searchable by ZIP Code. Volunteers keep location information up-to-date with input from users.

In support of open data access, our project aggregates and normalizes public data for researchers and journalists to promote informed decision-making for the common good.

Providing Response Advisory Teams to local decision makers in the U.S. Thousands of professional scientists help with COVID-19 research, testing, lab space, analytics, and materials.
