In Australia, we rely on voluntary, non-remunerated donations for blood and blood products, and only import blood products where needed. Each year ~3% of Australians donates blood (whole blood) and plasma (via plasmapheresis). According to Australian Red Cross Lifeblood, about 1 in 3 of us will need blood or blood products at some stage in our lives to treat existing conditions or following an emergency.
Blood contains approximately 55% plasma. Plasma is the clear to straw coloured liquid portion of blood that remains after red cells, white cells and platelets are removed. Plasma has multiple components with different clinical uses, and it cannot be manufactured in a laboratory.
