Convalescent plasma is being evaluated for effectiveness against COVID-19.  With no vaccines or proven, effective drugs against this disease, convalescent plasma may be effective treatment for patients battling the disease.

Cascade Regional Blood Services is currently collecting COVID-19 convalescent plasma for MultiCare Tacoma General Hospital, MultiCare Good Samaritan Hospital, MultiCare Allenmore Hospital, and MultiCare Auburn Medical Center.

“Community blood centers are at the forefront of delivering convalescent plasma to patients in critical need. This promising investigational product must get to patients without delay, and blood centers across the country have mobilized in response”

Kate Fry, CEO of America’s Blood Centers
