摘要:
Objective To understand the distribution of Rh blood group antigen in voluntary blood donors in Lishui district. Methods Rh blood group antigens were detected and analyzed by serological tests. The resalts were compared with other reports naitonwide. Results A total of 377 Rh-negative blood donors were identified in 76050 samples. Among them, 128 (33.95%), 102 (27.06%), 119 (31.56%), and 28(7.43%) samples were blood type A, B, O and AB, respectively. The results showed that ccdee (64.72%) was predominant in Lishui, followed by Ccdee of 23.34%, CCdee of 5.57%, and other phenotypes were relatively low. Compared with Eastern, Central, Southwest and Northeast China, the proportion of ccdee in Lishui was slightly higher, while the proportions of Ccdee, CCdee and ccdEe were the same as those in China. Conclusions The proportion of Rh-negative blood donors in Lishui area is simiar to the average level in China. The distribution of blood group antigen is unbalanced , which is dominated by ccdee.%目的 了解丽水地区无偿献血者Rh血型抗原分布情况.方法 应用血清学方法对献血者进行Rh血型抗原检测和分析,并与国内各地分布情况比较.结果 在76050人份样本中共确认Rh阴性377例,其中Rh阴性献血者中ABO血型分布为A型128例(33.95%),B型102例(27.06%),O型119例(31.56%),AB型28例(7.43%).血清学表型分布比例结果显示,丽水地区以ccdee为主占64.72%,Ccdee次之占23.34%,CCdee仅占5.57%,其他表型均比较低.与华东、华中、西南、东北地区相比,丽水地区ccdee比例略高,而Ccdee、CCdee、ccdEe比例则与我国各地区持平.结论 丽水地区无偿献血人群的Rh阴性比例符合我国平均水平,其血型抗原分布不平衡,以ccdee为主.
