重复献血者与初次献血者携带肝炎病毒可能性的比较

目的分析重复献血者与初次献血者携带肝炎病毒的可能性。方法以2002～2005年及2007～2010年间献血者资料为例,将献血者分为重复献血者和初次献血者,分析两类献血者的构成、献血间隔、血液筛查结果等资料,并对部分HBsAg和抗-HCV筛查结果进行确证。结果重复献血者捐献的血液占全部献血的比例由2002～2005年度的25.2%,上升到2007～2010年度的29.9%,平均年龄由38岁降至32岁;重复献血者捐献的血液HBsAg和抗-HCV不合格率明显低于初次献血者,且不合格样本的阳性确证率也明显低于初次献血者。结论重复献血者携带肝炎病毒的可能性较初次献血者低,是较安全的献血人群,应巩固和发展固定的无偿献血者队伍,保障血液安全。

The Comparative Analysis on the Possibility of Carrying Hepatitis Virus between Repeat Donors and First-time Donors

Objective To compare and analyze the possibility of carrying hepatitis virus between repeat donors and first-time donors. Methods The data from routine blood collection and screening during 2002 to 2005 and 2007 to 2010 were used. The donations were divided into repeat donations and first-time donations according to the donation time of the donors, and the donation interval of repeat donors were analyzed. The blood screening data were also analyzed and some of the reactive results of HBsAg and anti-HCV were confirmed. Results The composition rate of repeat donations was in- creased from 25.2% in 2002~2005 to 29.9~ in 2007~2010. The average age of repeat donors was decreased from 38 to 32 years old. The reactive rate of HBsAg and anti-HCV of repeat donations was significantly lower than that of the first- time donations. And the confirmation rate of reactive donations from repeat donors was also lower than that from the first- time donors. Conclusion The viral carrying possibility of repeat donors is lower than that of the first-time donors. Repeat donors are the safety donors and the non-remunerate voluntary blood donors should be emphasized and developed in order to improve the blood safety.
