Apheresis and Photopheresis may sound intimidating, but they’re really just high-tech terms for minimally-invasive procedures. Apheresis is a method of removing part of the blood, separating it into its various components, and returning the healthy portions to the body. Photopheresis treats those components with medications that are activated by exposure to ultraviolet light. Our state-of-the-art Apheresis and Photopheresis Program advances your child’s recovery following treatment for cancer, blood disorders, or other autoimmune diseases. The scientists at Children’s Hospital Oakland Research Institute (CHORI) have helped pioneer these procedures, making us a leading provider of photopheresis treatments in California.
