PROPORTION OF RHESUS BLOOD TYPE PHENOTYPES OF ROUTINE BLOOD DONORS AT BLOOD DONOR UNIT INDONESIAN RED CROSS IN BANDUNG CITY

Abstract

Blood type phenotype incompatibility including Rhesus between donors and patients may result in cross-matching problems, triggering alloimmunization, and caused Hemolytic Transfusion Reaction (HTR). Rhesus blood type incompatibility between mother and fetus may cause Hemolytic Disease of Fetus and Newborn (HDFN). Pretransfusion phenotypic blood groups matching also reduce cost efficiently which means antibody screening is no longer needed. The purpose of the study is to find the proportion Rhesus blood type phenotypes in routine blood donors at Blood Donor Unit, Indonesian Red Cross in Bandung city, Indonesia.The study is a descriptive and observational with cross sectional design. The study was done at Blood Donor Unit, Indonesian Red Cross in Bandung city from April 2016 to September 2017. The subjects were 142 routine blood donors, blood sampling was done simultaneously with blood donation. Rhesus antigen examination of ethylenediaminetetraacetic acid (EDTA) blood was done by gel method. Subjects characteristics were male (68%) and female (32%), with the mean age was 39 years. Examination of Rhesus antigen were found antigen D(100%), antigen e(98,6%), antigen C(97,9%), antigen c(38,7%) and antigen E(31,7%). Results of Rhesus phenotypes were DCe/DCe(61,3%), DCe/DcE(29,6%), DCe/dce(7%), DcE/DcE(1,4%) and DcE/dce(0.7%). The distribution of Rhesus blood type were affected by factors such as genetics, race, ethnicity, marriage, demography, and migration. Rhesus blood phenotypes proportion in routine blood donors at Blood Donor Unit, Indonesian Red Cross in Bandung city sorted from the most are DCe/DCe, DCe/DcE, DCe/dce, DcE/DcE and DcE/dce.Keywords: blood donor, phenotype, Rhesus
