One of the treatments initiated against the coronavirus, which affected the whole world, was plasma therapy. We have searched for you who are curious about this treatment method, which has started to be used in our country. It is transferred to people who are treated with plasma from people who have survived the disease. For this, blood donation is required. So how is immune plasma therapy done? Who can donate plasma?

Plasma therapy was first applied during the 2003 SARS epidemic, 2009 H1N1 influenza, 2012 Mers virus outbreaks. Plasma application, which has now been used for coronavirus, has provided positive effects, especially for the course of patients in the treatment phase. This method, which had positive results in studies conducted in the USA, is also applied in our country. For this, the Red Crescent asked people who survived the disease to donate blood. Plasma therapy is defined as “passive immune transfer” given for therapeutic purposes to hospitalized patients due to virus infection. In other words, blood taken from people who have survived the disease is given to patients in the treatment phase, increasing body resistance against the virus. The immune system switches to the production of antibodies against viruses. However, against very strong viruses, these antibodies remain immune. Plasma cells of survivors are stronger for coronavirus. Plasma B cells or plasmocytes produce stronger antibodies against this virus that they have become resistant to. Plasma cells are present in the body from birth. It is enriched with vitamins and minerals taken. It also contributes to development by protecting other body cells. It is present in the blood in liquid form all over the body. So it can be easily obtained by donating blood. Thus, when it is transferred from the person who has overcome the disease to the person who is fighting the disease, it can prepare the ground for a rapid recovery course.


The process of transferring blood from patients who have recovered for the treatment of the coronavirus epidemic to patients in critical condition is called immune plasma. Thanks to the antibodies in the blood of people who have survived the disease, resistance to the virus is increased. The process works as follows; Plasma, which is in the immunity of a patient who has survived the disease, enables the antibodies to become stronger and fight the virus more easily. These plasmas in the blood are transferred to the patients receiving treatment as blood. Attempts are made to strengthen immunity. However, this is not such an easy process. Because the eligible donor should not have any other disease. That’s why it goes through some tests. Just like in blood donation, the person fills out a form. From the appropriate ones, as much as the patient needs is taken by the method called apheresis. The process takes 45 minutes in total.
