Testing Insights

Johns Hopkins experts are working to fill the void of publicly accessible COVID-19 testing data. This initiative reflects an interdisciplinary collaboration between several groups at Johns Hopkins University: The Bloomberg School of Public Health, Applied Physics Laboratory, Center for Health Security, Center for Systems Science and Engineering (CSSE) in the Whiting School of Engineering, and the Centers for Civic Impact, with generous support from Bloomberg Philanthropies and the Stavros Niarchos Foundation.

Tracking serology-based tests for COVID-19

The Johns Hopkins Center for Health Security is tracking the development and availability of serology tests. Serology tests are blood-based, and can be used to determine whether individuals have been exposed to a particular pathogen by looking at antibodies, or proteins produced by the body in response to an infection. Serology tests can be helpful in determining whether someone was infected with the SARS-CoV-2 virus, which causes COVID-19, regardless of whether they ever developed symptoms of the disease. Serology tests can better quantify the number of cases of COVID-19 in the population, including those that may be asymptomatic or have recovered.
