Convalescent plasma

Our Scottish National Blood Transfusion Service (SNBTS) team has been part of UK-wide clinical trials collecting plasma from donors who have recovered from COVID-19, known as ‘convalescent plasma’, as a potential treatment for COVID-19 patients.

When someone recovers from COVID-19, they develop antibodies to fight the virus that causes the illness. These antibodies can be found in the recovered person’s plasma.

The clinical trials are researching whether plasma containing the antibodies is an effective treatment for COVID-19 patients.

SNBTS has been collecting convalescent plasma as a potential treatment for COVID-19 patients using two different methods. One is by giving blood in the usual way, where the plasma is separated from the blood after donation.

The second way is new – it’s called plasmapheresis and it’s where the donor is attached to a machine and only plasma is collected. It’s the first time plasmapheresis has been used in SNBTS to collect plasma although it's used regularly for platelet collection. A cross-specialty approach has allowed our team to introduce this new plasma collection method to support our efforts in finding a treatment for COVID-19.
