What is Convalescent Plasma Therapy?


This treatment involves taking plasma taken from patients who have recovered from COVID-19 and transfusing it into patients currently battling the virus.


How does it work?


As people fight the COVID-19 virus, their body produces antibodies to attack it. These antibodies are secreted by immune cells known as B lymphocytes. These are found in plasma -the liquid part of blood – which helps the blood clot and increases immunity.

Once a person recovered the antibodies stay in their body to fight the virus if it returns.


How much plasma is needed for each patient?

Plasma from one recovered patient can be used to treat two infected patients. One transfusion is enough to see results.


Who can donate plasma?

Anyone who has recovered from COVIDO19 can donate.


Is it being used in Qatar?

Yes, the treatment is being used on COVID-19 patients in Qatar. A Plasma Donation Center has been set up at the Communicable Disease Center.
