On May 13, 2020, Thermo Fisher Scientific announced it will expand its response to the COVID-19 pandemic by developing a total antibodies test in collaboration with WuXi Diagnostics and Mayo Clinic.

The new test is the result of ongoing collaboration between all three organizations, including clinical evaluation and support from Mayo Clinic. Thermo Fisher will seek U.S. FDA Emergency Use Authorization (EUA) and international regulatory authorizations for the test over the next few weeks.
