OBJECTIVES Hereditary resistance to activated Protein C (Factor V Leiden) is the commonest genetic defect known to confer a predisposition to thrombosis. This study aims to determine the prevalence of activated protein C resistance (APCr) in Lagos, and to determine if any association exists between APCr and ABO, Rhesus blood types, and hemoglobin phenotypes. MATERIALS AND METHODS A functional...

OBJECTIVES ABO and RhD blood groups are key factors affecting blood transfusion safety. The distribution of ABO and RhD blood groups varies globally, but limited data exist for ethnic distributions of these blood groups in Asian populations. We aimed to evaluate the distribution of ABO and RhD blood groups among Chinese ethnic groups. DESIGN A population-based cross-sectional study. SETTING...

BACKGROUND Up till now about 400 red cells antigen have been identified. The majority are inherited by Mendelian Fashion. The ABO blood group system was first to be identified and RH blood group system was the 4th one, both are most important for blood transfusion purposes. This study is conducted to determine the frequency of ABO and Rhesus (Rh) blood groups in District Swat, NWFP, Pakistan. I...

62 Abstract : On a sample of more than eleven thousand individuals residing in the wilaya of Tlemcen, we have determined the frequencies of blood groups A,B,O, rhesus plus and rhesus minus and the frequencies of the gene of these two systems A, B, O, D and d. Differences in phenotypic and genic frequencies have been revealed between the population Tlemcen town (urban area) it self on one side a...

The incidence of ABO and Rh blood group has been found to vary in various populations. The present investigation was undertaken with the aim to study ABO blood group frequency amongst a subset of population of Sikkim. A total of 5098 individuals were included in the study out of which 215 were students of Department of Zoology, Sikkim University and Government College, Tadong, East Sikkim, 3000...
