"Plasma therapy is really helpful in saving lives.We cannot say it is 100 percent successful... but the death rate has reduced in Delhi and plasma has a role in it," the chief minister said at the launch. The LNJP Hospital is located in central Delhi, so it is easily accessible to those willing to donate plasma, he said. COVID-19 patients can donate their plasma 14 days after recovery. Such people should be aged between 18 and 60 and weigh not less than 50 kg.
