Plasma is a yellowish liquid in your blood that carries platelets, red blood cells and white blood cells around the body.
Plasma makes up approximately 55% of your blood, and contains antibodies, known as immunoglobulins, which fight infection.
These antibodies are made into medicines to help people with cancers, rare diseases, immune disorders and genetic conditions.
