Convalescent plasma (plasma) is yellow liquid portion of the blood which contain
antibodies to fight against the novel coronavirus (SARS-COV2). It is obtained from blood
donated by fully recovered COVID-19 patients, who are asymptomatic. The blood is processed
by blood bank to extract plasma. Convalescent plasma is being used to treat severe SARS-COV2
infection as it was clinically shown to be helping some patients recovering from serious illness.
Current evidence of its effectiveness is based on clinical experience and its previous use
during Ebola pandemic. Increased number scientific papers are being produced on this topic.
As there is no effective proven treatment available for SARS-COV2 at this time, convalescent
plasma is being used as drug under
investigation in some countries and on ethical grounds in other countries.
