Red Blood cells can be stored for up to 42 days. Frozen red Blood cells can be stored for 10 years. Platelets can be stored for only five days. Platelets must be used within five days. Platelets help Blood to clot and give those with leukemia and other cancers a chance to live.
Platelets are small Blood cells that help control bleeding.
Frozen Plasma can be stored for up to one year. Plasma is a pale yellow mixture of water, protein and salts. Plasma, which is 90 percent water, constitutes 55 percent of Blood volume. Plasma helps maintain Blood pressure, carries Blood cells, nutrients, enzymes and hormones, and supplies critical proteins for Blood clotting and immunity. Red Blood cells, white Blood cells, platlets and platelets are made naturally by the body in the bone marrow.
