Prevalence, Gender Distribution, and Allelic Distribution of ABO and Rh-D Blood Groups in AL-Salim Laboratory for Medical Analysis, Ajdabiya, Libya

Objective: To determine the prevalence of ABO, ABO blood groups, Rh factor frequency, gender distribution, and allelic distribution in the AL- Salim laboratory for medical analysis at Ajdabiya City. Methodology: ABO and Rh blood group tests. The study of blood group determination (hemoclassification) and Rh factor determination was carried out between January and December 2019. Results: Total number of 2095 individuals were collected from the AL-Salim laboratory for medical analysis at Ajdabiya City show that phenotype O is the most common with a frequency of 38.56801 %, followed by phenotype A (29.642004 %), B (16.5632458 %), and AB (15.22673031 %). The calculated allelic frequencies were 0.2048624908, 0.1741059592, and 0.6210315539, for IA (p), IB (q), and IO (r), respectively. In Addition, it was found that 78.9498806 % of the individuals were Rh+ and 21.050119 % were Rh-. Conclusion: Blood group O and Rh+ factor were dominant in both genders. There is no relationship between gender and the distribution of ABO and Rh blood groups.
