Background of Study

Blood is characterized as the red gooey liquid that flows round the body providing O2 and nutritive substances consumed from the gastrointestinal lot to the tissues, returns CO2 to the lungs and different results of digestion to the kidneys, capacities in the guideline of internal heat level, and disseminates chemicals and different specialists that manage cell functional (Saladin, 2003; Barrett et al., 2010).

Blood has always had a special mystique. From time immemorial, people have seen blood flow in the body and with it, the life of individual depends. People thus presumed that blood carried a mysterious ―vital force, and Roman gladiators drank it to fortify themselves for battle. From ancient Egypt to nineteenth-century America, physicians drained ―bad blood‖ from their patients to treat everything from gout to headaches, from menstrual cramps to mental illness (Saladin, 2003).

Blood group can be defined as inherited allogeneic variation detected on the surface of blood cells (Daniels, 2002). The term applies to a defined system of red blood cell antigens (blood group substances) controlled by a genetic locus having a variable number of alleles e.g. A, B, and O in the ABO system (Murray et al., 2003; Daniels, 2002). The blood group is determined by the genetic make-up of the alleles of a system (Bakare et al., 2006; Bhuvnesh et al., 2011).

There are basically other 29 realized blood bunches with a sum of in excess of 240 antigens, including the MN, Duffy, Kell, Kidd, and Lewis gatherings (Storry and Olsson, 2004). These seldom cause bonding responses. The Kell, Kidd, and Duffy bunches sporadically cause. Haemolytic Disease of the Newborn (Iyiola et al., 2011).The most renowned blood bunches are those of ABO and Rhesus (Rh) series (Khan et al., 2009). The ABO blood bunch are the main red cell antigens while the Rhesus blood bunch are the most immunogenic red cell antigens found (Chima et al., 2012). Both are regularly composed for in any blood donation center or blood bonding administration (Bakare et al., 2006; Enosolease and Bazuaye, 2008).
