Convalescent plasma therapy has been used in Austin to treat COVID-19 patients. However, as health officials expect a second spike in cases in November, We Are Blood, Central Texas’ blood bank, will be testing all blood donations for COVID-19 antibodies as an effort to identify more convalescent plasma donors. Jeff Yorio, M.D., hematologist and medical oncologist at Texas Oncology–Austin Central, explains that hundreds of local COVID-19 patients have received convalescent plasma transfusions as part of their treatment.
