Abstract: Determination of blood groups of the ABO system and Rhesus(Rh)groups hassignificant impact on people health during blood transfusion.Therefore, understanding the prevalenceof blood groupin a particular areais important to know any shortages of any blood groupparticularly during disasters.To Study the prevalence of blood groups of the ABO system and Rhgroupsin inWest Coast regions (Regdalin, Aljmail and Zaltan-Libya,the ABO and Rh systems weredeterminedby presence of antigenA and antigen-B for the ABO system and antigen D for Rh groups on erythrocytes.Which, detected byagglutination on the slide when mixed drops of blood with specialized sera to enable us for identification themost common and lowest blood groups and their Rh among the donorsinthestudy regions. Among the 354 of examined samples (i.e.,354 persons), we found that percentage of blood groupsas 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, inAl 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 findingreveledthat positive Rh of (O)blood groupwasthe most common, followed by (A)group, (AB)group, and (B)blood group; negative Rhblood groups were the lowest. The outcomes of this study areimportant 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 tocall them in case of emergency need of blood donation.
