Phenotype blood transfusion

ABSTRACT

The study was carried out on 98 patients who needed to be transfused regularly. Phenotyped red blood cells of groups were used for this purpose. Only immunogenic antigens of the common blood groups were included in this study, such as Rh, MNSs, Duffy and Kidd systems. The highest quantity of units transfused depassed the number 44. After a period of thirteen months, there was no antibody detected. But in the other hand, we found 4 cases of immune antibodies in patients who previously received multiply transfusions of non phenotyped blood. These antibodies belong to Rh, Duffy and Kidd systems which are highly immunogenic. These results showed the need and importance of performing adequate compatibility testing for multiply transfused patients and the benefit of using phenotyped blood for those who need regular transfusions.
