Turn Around Time

No more than 450 mL of whole blood is usually drawn from the patient at any one time. The goal is to reduce the hematocrit to less than 50% for secondary polycythemia. Procedure can be repeated subsequently. Therapeutic phlebotomies for emergency reduction of blood volume to treat cardiogenic failure and other serious conditions in inpatients should be performed at the patient’s bedside by clinical staff. Apheresis staff are not approved to perform inpatient therapeutic phlebotomies.
