ABO; Blood groups; Population genetics; Rh (D) Abstract Background: Frequency distribution of blood groups is important as it is used in modern medicine, genetic research, anthropology, and tracing ancestral relations of humans. The ABO and Rh blood groups are the most important blood groups despite the long list of several other blood groups discovered so far. Aim of the study: To study and do...

OBJECTIVE Aim of our study was to evaluate distribution of ABO and Rh blood type groups in children after hip surgery regarding transfusion administration and fever presence. METHODS Four types of ABO blood groups (A; B; AB; O) and 2 types of Rh blood groups (Rh+; Rh-) were evaluated in group with administered transfusion (tr+) and without given transfusion (tr-); and in group with fever (fev...

Objective: To study phenotypic prevalence of ABO, Rh and Kell blood group system Material and Method: Voluntary blood donors were tested for red cell antigen of ABO, Rh (D, C, c, E, e) and Kell (K) blood group systems. Each sample was tested using LISS/Coombs ABO-Rh gel card and DiaClon Rh subgroups +K gel card. Calculations of antigen and phenotypes frequencies were expressed as percentages an...

OBJECTIVE To determine the distribution of ABO blood group and rhesus (RH) factor among pregnant women, to estimate the prevalence of Rh alloimmunization, and report the perinatal outcome of all cases of Rh alloimmunization at King Abdul-Aziz University Hospital (KAUH). METHODS This is a retrospective study of pregnant women attending the antenatal clinics in KAUH, Jeddah, Saudi Arabia betwe...

The Rhesus (Rh) blood group system is one of the most complex systems. Over 46 different antigens have been serologically defined. Rh antigens are associated with the red cell membrane and are considered important fortheir integrity. The genes for Rh antigens are encoded together on the short arm of chromosome. One gene codes for Rh D antigen while the other gene encodes the polypeptide carryin...

The frequencies of ABO and rhesus blood groups vary from one population to another. We studied blood group distribution in 120 Nepalese students; 34% were blood group A, 29% group B, 4% group AB and 32.5% group O. The frequency of Rh-negative blood was 3.33% and Rh-positive 96.66%.

AIM To investigate the correlation between breast cancer in Greek women and ABO blood groups. MATERIAL-METHODS In 166 female patients with breast cancer factors such as blood group, histological type, family history, presence or absence of nodal and/or distant metastases were examined. These patients had similar demographic, clinical, surgical, immunohistochemical, laboratory, and follow-up d...
