不同采血模式无偿献血者HBsAg阳性率的调查

Study on HBsAg carrying rate among unpaid blood donors of different blood colletion model in Liuzhou City

目的了解2002～2007年柳州市149035名无偿献血者血液HBsAg感染状况和民族分布，以确保输血安全和保护受血者利益。方法使用ELISA法对2002～2007年33个民族149035名无偿献血者进行HBsAg测定。结果检测无偿献血者149035人次，不合格1762人次，HBsAg阳性率为1．18％，不同采血模式无偿献血者血清学样本HBsAg阳性率比较有显著性差异。模式2中首次献血者血清样本HBsAg阳性率为1．57％。重复献血者血清样本HBsAg阳性率为0．62％，两者比较有显著性差异；但模式1中两者比较无统计学意义。结论严格无偿献血者HBsAg检测，对减少医疗纠纷的发生，避免输血后感染起到重要作用。

Objective To survey the status of HBsAg infection in 149 035 unpaid blood donors from 2002 to 2007. Methods The infection rate of HBsAg in149 035 samples from unpaid blood donors of 33 nationaUities with sampling model one and sampling model two were detected with ELISA from 2002 to 2007.and the results were analyzed. Results The HBsAg positive rate among these unpaid blood donors was 1.18% with significant difference between blood sampling model one and tow . The HBsAg positive rate in unpaid blood donors for the first time was 1.57% and 0.62% in the repeated unpaid blood donors. The prevalent rates of HBsAg were significant difference between first time donors and repeated donors among model mone and model two. Conclusion The detection of HBsAg in unpaid blood donors is necessary for reducing HBV infection and medical disppute.
