A longitudinal study of convalescent plasma ( <scp>CCP</scp> ) donors and correlation of <scp>ABO</scp> group, initial neutralizing antibodies ( <scp>nAb</scp> ), and body mass index ( <scp>BMI</scp> ) with <scp>nAb</scp> and anti‐nucleocapsid ( <scp>NP</scp> ) <scp>SARS‐CoV</scp> ‐2 antibody kinetics: Proposals for better quality of <scp>CCP</scp> collections

Abstract

Selection of CCP donors for multiple collections based on initial high nAb titers (≥1280) or BMI ≥ 30 kg/m² provides a simple strategy to achieve higher quality in CCP programs. High IgG anti-NP levels can also be used as surrogate markers for high nAb screening.
