What is Apheresis?
Hemapheresis, (also called Apheresis), is a procedure used in the treatment of a variety of illnesses by which blood is removed from the body and separated into its 4 components: plasma, platelets, white blood cells, and red blood cells. The targeted blood component is then removed and the remaining blood cells, with or without a replacement fluid, are returned to the patient. This removal and replacing of the blood is done simultaneously to maintain proper fluid balance.
Most procedures are performed on an outpatient basis, during normal business hours. However, we have a team of apheresis physicians and nurses on call at any time for patients with urgent medical needs, and can provide apheresis treatment in any location in the hospital.
For more information, please refer to our HATS Apheresis Patient Education Brochure.
Our mission is to provide excellent quality healthcare to all patients in a safe, compassionate manner. We work closely with physicians to provide the therapy selected for your care.
