应用血清学和分子生物学方法筛选浙江汉族人群中部分稀有血型

本研究探讨浙江汉族人群部分红细胞血型系统稀有表型的分布情况。利用血清学技术或分子生物学方法分别筛选H系统H-、MNS系统GPA-和s-、Rh系统Rhnull、Rhmod、D--、CCDEE和CCdEE、Gerbich系统GPC-、I系统i+、Lutheran系统Lub-、Kell系统k-和Jsb-、Duffy系统Fya-、Ok系统Oka-、Diego系统Dib-。利用尿素溶血试验筛选Kidd系统Jk(a-b-)表型。结果表明:1 618例献血者中检出1例Di(a+b-),1 007例献血者检出3例Fy(a-b+),633例Rh阴性献血者检出1例CCdEE。大规模筛选中未发现Jk(a-b-)、H-、GPA-、s-、GPC-、成人i+、Lub-、k-、Jsb-、Lub-和Oka-稀有血型。结论:在献血人群中发现Di(a+b-)、Fy(a-b+)、CCdEE稀有表型,提供了浙江汉族人群部分红细胞稀有血型的分布数据。

Rare blood group screening by serological and molecular methods in Zhejiang Han population

This study was aimed to investigate the distribution of rare blood group in Zhejiang Han population. The H(-) (H system), GPA(-) and s(-) (MNS), Rhnull, Rhmod, D--, CCDEE, CCdEE (variations of Rh), GPC(-) (Gerbich), i(+) (I), Lu(b-) (Lutheran), Js(b-) and k(-) (Kell), Fy(a-) (Duffy), Ok(a-) (Ok), Di(b-) (Diego) phenotypes were screened by serological or molecular methods. Jk (a-b-) phenotype was detected by urea hemolytic test. The results showed that one Di (a+b-) individual was found in 1618 blood donors, three Fy (a-b+) individuals in 1007 donors and one CCdEE individual in 633 Rh negative donors. No Jk (a-b-), H(-), GPA(-), s(-), GPC(-), i(+) (adult), Lu(b-), k(-), Js(b-), Lu(b-) and Ok(a-) phenotypes were found in this large scale survey. It is concluded that Di (a+b-), Fy (a-b+), CCdEE phenotypes are confirmed in the blood donors and this study provides the distribution data of erythrocyte rare blood group in Zhejiang Han population.
