长沙地区无偿献血者血液检测结果分析

目的:了解长沙地区无偿献血人群中检测不合格情况及变化规律并分析原因,为今后开展工作提供参考。方法:采用回顾性调查方法,收集2005²012年长沙地区812 088名无偿献血者血液检测结果,并采用χ2检验进行统计分析。结果:812 088份检测结果中总体不合格率为6.46%。ALT、HBs Ag、Anti-HCV、Anti-HIV、Anti-TP五项检测结果不合格率均有显著差异(χ2值分别为25 438.708、253.495、747.226、260.777、295.934,均P<0.05)。ALT不合格率呈现先升后降的趋势,丙肝与梅毒的不合格率大致为上升趋势,HBs Ag阳性检出率呈先降后升趋势,Anti-HIV初检阳性率变化不大。结论:血液检测不合格情况与相应疾病的流行病学趋势相关,献血前严格筛查与建立一支固定的无偿献血队伍是降低血液不合格率的有效途径。
