Many different manipulations are performed with donated blood. First, it is checked for the presence of diseases, foreign particles and other things. Then special preparations are added to it. This helps to stop the process of blood clotting in storage tanks. This allows the blood to be stored for quite a long time.

Special solutions can also be added to the blood to increase the volume in case of emergency transfusion.
