Two more coronavirus patients have been administered plasma in Hyderabad, according to the head of Diagnostic and Research Laboratory of Liaquat University of Medical and Health Sciences (LUMHS), Dr Ikram Ujjan.

This brings the total number of patients who have been administered the said treatment in Hyderabad to six.

Plasma therapy involves collecting blood from someone who has recovered from Covid-19 and transfusing separated plasma to a critically sick patient. The transfusion of plasma with its antibodies provides a form of "passive immunity" to the sick recipient to fight the infection.
