Abstract
The aim of this research is to search for the distribution of blood groups in all the regions of Morocco. This study, done for the first time, aimed to provide the frequency of the Rhesus system and Kell (K) in more than 55000 blood donors from nine different regions around the country. In addition, the frequency of the Cellano, Duffy, Kidd, and MNS blood antigens was searched for 500 blood donors from the Rabat's region. Frequency of blood donors with rare blood groups was characterized for the first time in the country and compared to results found from other populations.
Highlights
Blood group phenotypes have been used for several applications as for blood transfusion practices and population genetic studies [1,2,3].In Morocco, no study has identified yet the distribution and frequency of different blood groups
We have conducted a study to determine the frequencies of the k, Fya, Fyb, Jka, Jkb, S, and s antigens in blood donors (BD) from the Rabat region
We examined the composition of RBC antigens in Moroccan BD
Summary
Blood group phenotypes have been used for several applications as for blood transfusion practices and population genetic studies [1,2,3]. In Morocco, no study has identified yet the distribution and frequency of different blood groups. In this perspective we tried to identify the Rhesus phenotypes in nine different regions spanning the whole country. We have conducted a study to determine the frequencies of the k (cellano), Fya, Fyb, Jka, Jkb, S, and s antigens in blood donors (BD) from the Rabat region
