Southern California: Looking for plasma donation for a covid-19 hospitalized physician. Are you aware of any local patients blood type A+ or AB+ that recovered from covid-19 that might be willing to donate plasma?

He has received all known experimental treatments for which he is eligible other than transfusion of convalescent plasma. Additional considerations for donor eligibility should be addressed, as follows:
Prior diagnosis of COVID-19 documented by a laboratory test

Complete resolution of symptoms at least 14 days prior to donation
Female donors negative for HLA antibodies or male donors
Negative results for COVID-19 either from one or more nasopharyngeal swab specimens or by a molecular diagnostic test from blood.
