Blood fractionation immune globulin. Human serum albumin prepared by this process is used in some vaccines, for treating burn victims, and other medical applications. Blood fractionation Blood fractionation is the process of fractionating whole blood, or separating it into its component parts. This is typically done by centrifuging the blood. The resulting components are: Serum separation tubes (SSTs) are tubes used in phlebotomy containing a silicone gel; when centrifuged the silicone gel forms a layer on top of the buffy coat, allowing the blood serum to be removed more effectively for testing and related purposes. Plasma proteins are separated by using the
Packed red blood cells Packed red blood cells Packed red blood cells, also known as packed cells, are red blood cells that have been separated for blood transfusion. They are typically used in anemia that is either causing symptoms or when the hemoglobin is less than usually 70–80 g/L (7–8 g/dL). In adults, one unit brings up hemoglobin levels by about 10 g/L (1 g/dL). Repeated transfusions may be required in people receiving cancer chemotherapy or who have hemoglobin disorders. Cross matching is typically required before the blood is given. It is given by injection into a vein. Side effects include allergic reactions such
