Abstract
Background: ABO and RH D systems are related to ethnicity and diseases.
Objectives: To study the ABO and Rh groups in Fazzan area where the population are of mixed origin.
Setting: The 2nd March Hospital's blood transfusion unit.
Material and Methods: The population in this study are those attending delivery room and Obstetric units and those who donate blood during the period between January 2003 and December 2003.
Results: Blood group O is found to be the most frequent blood group in this study(48.2%): 50.4 % in male donors and 45.9 in female recipients. ORh+ is 42.4%in female recipients and 45.4% in male donors. On the other hand, the least frequent group is group AB (4.8%). The highest percentage of blood group O is found in Obari area (63.5%) and the least in Morzok (41%). About ninety two per cent (92.3%) of the donors are Rh positive, and 91% of the recipients are Rh positive. Both recipients and donors are 91.6 % Rh positive. Attendants with Rh negative were 8.4%: female recipient are 9% and male donors are 7.7%. There is no significant difference in the distribution of blood groups and Rh D system between male donors and female recipients.
Conclusion: Our results show that the most frequent blood group in Libyans of Fazzan province is group O and is nearly similar to that of Africans. Blood group A is similar to that of Arabs and Africans. Blood group B is nearer to Africans more than Arabs. The least frequent blood group is AB which is similar to that of Africans. The study of blood groups in Libya is very important for Blood Banks and transfusion service policies. Knowledge of blood group phenotype distribution is also important for clinical studies (for example disease association) as well as for population studies
