Abstract

Relationship between Rhesus factor and bleeding time in blood group O subjects selected randomly from Niger Delta University, Bayelsa State, Nigeria was investigated, using standard antisera and Duke’s method. Group O+ subjects had shorter bleeding time (1.32 ± 0.41min) than O- (1.33 ± 0.37 min). Gender-wise, group O+ females had shorter bleeding time (1.30 ± 0.40 min) than male O+ (1.34 ± 0.42 min), and males with O- blood type had shorter bleeding time (1.20 ± 0.39 min) than female O- (1.39 ± 0.37 min). Comparison within same gender shows that group O+ males had longer bleeding time (1.34 ± 0.42 min) than O- males (1.20 ± 0.39 min), and the females with blood type O+ had shorter bleeding time (1.30 ± 0.40 min) than O- females (1.39 ± 0.37 min). All these observed differences were statistically significant at p< 0.05. In conclusion, the current study suggests that generally, blood group O+ individuals have shorter bleeding time than O-. Bleeding time appear prolonged in O+ males than O+ females and prolonged in O- females than O- males. Within gender, O+ males appear to have longer bleeding time than O- males, while O+ females have shorter bleeding time than O- females.

Key words: Rhesus factor, Blood group O, Bleeding time, male, female.
