These components include red blood cells‚ plasma and platelets where these products are then used for many purposes in the medical field. Red blood cells (RBC)‚ which can be turned into a concentrate with 2 times more red blood cells than whole blood‚ is critical in treating patients with anaemia (a deficiency in the quantity or efficiency of red blood cells)
