Autologous blood donations are very common. Current FDA guidelines allow patients to donate as many whole blood units as needed (within the 42 day shelf life of AS-1 red cell units) as long as the pre donation hematocrit is 33% or higher. Most facilities do not recommend autologous donations within 7 days of the scheduled surgical procedure.
