Rare blood group screening by serological and molecular methods in Zhejiang Han population / 中国实验血液学杂志

ABSTRACT

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.
