Hospital-Based Donor Recruitment and Predonation Serologic Testing for COVID-19 Convalescent Plasma.

Objectives: Serologic testing for antibodies to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in potential donors of coronavirus disease 2019 (COVID-19) convalescent plasma (CCP) may not be performed until after blood donation. A hospital-based recruitment program for CCP may be an efficient way to identify potential donors prospectively.

Methods: Patients who recovered from known or suspected COVID-19 were identified and recruited through medical record searches and public appeals in March and April 2020.
