DETROIT – Versiti said the supply level for convalescent plasma from COVID-19 survivors is dwindling. Convalescent plasma from those who have recovered from COVID-19 contains antibodies that can bind to the virus that causes COVID-19, neutralizing it. Versiti is asking community members who have tested positive for COVID-19 and recovered to donate plasma. You are eligible if you’ve had a confirmed diagnosis of COVID-19 by a physician and laboratory testing. READ: Michigan Medicine awarded funding for COVID-19 plasma therapy trial
