title: [Significance and Clinical Application of the Establishment of RhD/C/c/E/e Blood Group Base in Chinese Nanyang City].
abstract: OBJECTIVE
  To understand the regularity of Rh blood typing of valunteary blood donors in Chinese Nanyang city, and to estabbish a Rh DC/c/E/e antigen negative donor base so as to provide the help for clinical emergent blood transfusion to patients and ensure the safety of blood transfusion.
  
  
  METHODS
  The Rh D blood group of blood samples from 81462 voluntary blood donors in Chinese Nanyang city in 2014 was identified by serologic method; after first screening and confirmation, the RhE/e/C/c typing of Rh D negative samples was performed; the detailed infornation of donors was registered seriously by using unified creteria; the data base and base in kind of RhE/e/C/c types of valuntary donors were established by means of compater-mamayement system.
  
  
  RESULTS
  300 cases (0.37%) were RhD negative blood donors, and the Rh antigen was Ccdee and ccdee in 83%.
  
  
  CONCLUSIONS
  The proportion of RhD negative donors accounts for 4% of Chinese Nanyang peoples, the RhE/e/C/c types of RhD negative donors are ccdee (50.67%)>Ccdee (33.00%)>ccdEe(5.67%)>CCdee (5.33%)>CcdEe(5.33%). The establisment of RhE/e/C/c subbase can show importent significance for clinical blood transfusion.
