White Blood Cells | Time 4 hours *
White blood cells are cells of the immune system that protect the body against infectious disease. This makes them invaluable to researchers working on new therapies in the fight against cancer, autoimmune diseases, and other rare illnesses.
Collection process: White blood cells are collected from an arm vein by leukapheresis, a type of blood collection that removes whole blood from the donor, separates the white blood cells, and returns the remaining blood components back to the donor in the other arm.
