The Food and Drug Administration announced on Friday that it has authorized the first serology test that screens for neutralizing antibodies caused by a previous coronavirus infection.
Neutralizing antibodies prevent viruses from infecting cells, though questions remain about how long antibodies against Covid-19 last and how much protection they provide. The new serology test will help researchers study the neutralizing antibodies, said Dr. Tim Stenzel, director of the Office of In Vitro Diagnostics and Radiological Health in the FDA’s Center for Devices and Radiological Health.
