blood components and their uses.

Blood Components:- Blood components are prepared from a single blood donation by simple physical separation methods e.g. by centrifugation. The use of plastic bags instead of glass bottles has facilitated separation of blood components. The separated components can then be transferred aseptically into other container bags, stored and transfused individually, avoiding the hazard of contamination of components.

Blood Fractions or Derivatives:- Blood fractions or derivatives are prepared by pooling the plasma from many donors which is then subjected to more complex physical and chemical processes. Unlike blood components, which can be prepared in any well equipped blood blank, blood fractionation is still a very complex manufacturing process usually undertaken-by the pharmaceutical industry.

Transfusion by Haemapheresis:- Haemapheresis is a process in which whole blood is taken from a person, the required component separated and retained, and the remainder returned to the individual's blood stream. The whole process is done in one sitting. This procedure is useful for two purposes: to obtain certain blood components from a donor for transfusion, and to remove harmful components from patient's blood (therapeutic apheresis or plasma exchange).
