Blood fractionation

Definition

Blood fractionation is the process of separating whole blood into its individual components, such as red blood cells, plasma, and platelets. This process allows for the targeted use of specific blood components in medical treatments.

5 Must Know Facts For Your Next Test

1. Blood fractionation is crucial for creating different blood products used in transfusions and therapies.
2. The main components separated during fractionation are red blood cells, white blood cells, platelets, and plasma.
3. Plasma from fractionated blood can be further processed to extract clotting factors essential for treating hemophilia patients.
4. Fractionated blood products are often used in total parenteral nutrition (TPN) to ensure patients receive necessary nutrients intravenously.
5. Proper storage conditions vary for each fractionated component; red blood cells require refrigeration while plasma is often frozen.
