Bottom Line: To avoid and reduce such complications, blood products are modified as leukoreduced products, irradiated products, volume reduced products, saline washed products and pathogen inactivated products.PRBCs can be stored for years using cryopreservation techniques.New researches in red cell cultures and blood substitutes herald new era in blood banking.

ABSTRACT
The whole blood which is a mixture of cells, colloids and crystalloids can be separated into different blood components namely packed red blood cell (PRBC) concentrate, platelet concentrate, fresh frozen plasma and cryoprecipitate. Each blood component is used for a different indication; thus the component separation has maximized the utility of one whole blood unit. Different components need different storage conditions and temperature requirements for therapeutic efficacy. A variety of equipments to maintain suitable ambient conditions during storage and transportation are in vogue. The blood components being foreign to a patient may produce adverse effects that may range from mild allergic manifestations to fatal reactions. Such reactions are usually caused by plasma proteins, leucocytes, red cell antigens, plasma and other pathogens. To avoid and reduce such complications, blood products are modified as leukoreduced products, irradiated products, volume reduced products, saline washed products and pathogen inactivated products. The maintenance of blood inventory forms a major concern of blood banking particularly of rare blood groups routinely and common blood groups during disasters. PRBCs can be stored for years using cryopreservation techniques. New researches in red cell cultures and blood substitutes herald new era in blood banking.

Mentions: Blood component preparation was developed in 1960 to separate blood products from one unit whole blood by a specialised equipment called as refrigerated centrifuge.[3] Preparing only PRBC and fresh frozen plasma (FFP) is by single-step heavy spin centrifugation; however preparing platelet concentrates (PLTCs), PRBC concentrates and FFP is by two step centrifugation. The two main procedures of preparing PLTC are either by platelet-rich plasma (PRP) method or BC method. The algorithm for the separation by the two methods is given as Algorithm no. 1 and 2. PRP method is simple, easily done manually and comparatively cheaper, but platelet and plasma yield is less. BC is a better method but complicated if done manually and hence needs automation.
