Various antibodies of the ABO blood group systems and the Rh factor (anti-A, anti-B, anti-D) and phenotype systems (anti-E and anti-c of phenotypes E and c) were used for the blood analysis.

The results of present study were strongly in favor of these past studies expressing the similar order of frequency of ABO blood groups.
