【摘要】 目的 分析不同ELISA试剂在血液筛查梅毒的结果。 方法 使用全自动加样仪和酶免分析仪,分别用不同厂家ELISA试剂对血标本做梅毒螺旋体抗体筛查,阳性标本用TPPA试剂确诊。结果 2006—2008年共检测标本86788份,ELISA检测阳性476份,经TPPA确认阳性235份,真阳性率0.271%,假阳性率0.278%。 结论 采用灵敏度高、特异性好的试剂,切实做好无偿献血者梅毒血清筛查工作,进一步提高血液质量,确保输血安全;对梅毒筛查阳性的献血者,采用TPPA试剂确认,保障献血者的利益。 【关键词】 血液筛查;梅毒螺旋体抗体; ELISA 检出率 作者:孙昂,罗志红,彭海波 作者单位:414000 湖南岳阳,岳阳市中心血站 The examination result of microspironema pallidum antibody by different ELISA reagent SUN Ang, LUO Zhi-hong, PENG Hai-bo.The Central Blood Station of Yueyang City, Hunan 414000,China 【Abstract】 Objective To analyze the examination result of microspironema pallidum antibody by different ELISA reagents.Methods Blood samples were treated with automatic sample and automatic enzyme immunoassay analyzer, and examined by different ELISA reagents for screening of anti-TP and positive samples were confirmed by TPPA reagents.Results Since 2006 year to 2008 year, 86,788 blood’s samples were examined by ELISA reagent, 476 blood’s samples were positive and were confirmed by TPPA, 235 blood’s samples which confirmed by TPPA were positive, the true positive rate of 0.271%, the false positive rate of 0.278%.Conclusion Anti-TP is examined with high sensitivity and good specificity reagents, and done good job in examining blood donors for syphilis serum work, can further improve the quality of blood and ensure blood transfusion safety. Anti-TP positive blood donors are confirmed by TPPA reagents can protect the benefits of blood donors.

梅毒是由苍白螺旋体引起的,传播途径主要有三种,即性传播、母婴传播和血液传播。为了保证受血者安全,采供血机构一直将梅毒定为必检项目之一,1996年卫生部又规定使用两种不同厂家的试剂对血液进行初复检。梅毒血清学的筛查方法从TRUST、RPA发展到ELISA。自2006年1月开始,我站全部使用ELISA试剂筛查梅毒螺旋体抗体,并对筛查阳性标本用TPPA试剂确认。我们对两种不同厂家ELISA试剂检测梅毒螺旋体抗体的结果和确认结果报告如下。 1 材料与方法
1.3 试剂 梅毒螺旋体抗体初复检用ELISA 试剂盒A、B均为国产试剂,确认用TPPA试剂盒(日本富士瑞必欧株式会社)。所有试剂均经中国药品生物制品检定所批检合格,在有效期内使用。 1.4 方法 用两种ELISA试剂分别检测无偿献血者血液标本中是否存在梅毒螺旋体抗体,所有操作均严格按试剂使用说明书进行。两种试剂均阳性的标本不复检,一种试剂阴性另一种试剂阳性的,采用2孔复查,以复查结果为准。对结果呈阳性的标本(两种试剂阳性,1种试剂阴性1种试剂阳性),均用TPPA试剂进行确认。 |
