Prevalence Study of the Blood Groups and Their Rhesus Groups in Some Western Coast Regions - Libya

الملخص

Determination of blood groups of the ABO system and Rhesus (Rh) groups has significant impact on people health during blood transfusion. Therefore, understanding the prevalence of blood group in a particular area is important to know any shortages of any blood group particularly during disasters. To Study the prevalence of blood groups of the ABO system and Rh groups in in West Coast regions (Regdalin, Aljmail and Zaltan- Libya, the ABO and Rh systems were determined by presence of antigen A and antigen-B for the ABO system and antigen D for Rh groups on erythrocytes. Which, detected by agglutination on the slide when mixed drops of blood with specialized sera to enable us for identification the most common and lowest blood groups and their Rh among the donors in the study regions. Among the 354 of examined samples (i.e., 354 persons), we found that percentage of blood groups as following: In Ragdalin; (O+) was 41.3%, (A+) was 28.6%, (AB+) was 7.4%, (O ─) was 6.9%, (B+) was 6.8%, (A─) was 4.3%, (AB─) was 3.2% and (B─) was 1.6%. While, in Al jmile; (A+) was 29.3%, (O+) was 27.3%, (AB+) was 16%, (B+) was 10.3%, (A─) was 7.5%, (AB─) was 4.7%, (O─) was 3.7% and (B─) was 0.9%. Whereas, In Zaltan; (O+) was 32.3%, (A+) was 27.1%, (AB+) was 10.2% = (A─) was 10.2%, (B─) was 6.8%, (B+) was 5.7%, (O─) was 5.7% and (AB─) was 3.4%. This finding reveled that positive Rh of (O) blood group was the most common, followed by (A) group, (AB) group, and (B) blood group; negative Rh blood groups were the lowest. The outcomes of this study are important to identify donors and their blood (ABO) system in the region, to establish blood donation database which would be used to build up blood bank, in addition to call them in case of emergency need of blood donation.
