Screening of JK(a-b-) phenotypes of Kidd blood group in children of certain area

目的筛选深圳地区儿童Kidd血型中JK(a-b-)表型。方法采用96孔微量板法尿素溶血实验从20 453例样本中筛选溶血阴性样本,血清学实验确认JK(a-b-)表型。结果 20 453例样本中筛选出4例JK(a-b-)表型,检出率为4∶20 453,频率为0.019 6。结论深圳地区儿童Kidd血型JK(a-b-)表型的检出率略低于广东番禺地区,但明显高于广东韶关、上海、中国台湾、中国澳门、日本等其他地区。

Objective To screen the JK（a-b-） phenotypes of Kidd blood group in children of Shenzhen.Methods 20 453 cases of samples were screened for JK（a-b-） phenotypes by urea lysis test using 96-well microplates and the JK（a-b-） phenotypes were confirmed by serum test.Results Among the 20 453 cases of blood samples,4 cases were positive with JK（a-b-） phenotypes.Conclusion The positive rate of JK（a-b-） phenotypes in Shenzhen was slightly lower than that of Panyu district of Guangdong,but significantly higher than that of Shanghai,Shaoguan Guangdong,Taiwan China,Macao China,Japan and other regions respectively.
