Keyword:  磁微粒化学发光法术前四项定量应用价值;
Abstract: 目的了解术前四项检查的临床价值。方法用磁微粒化学发光法对6212例患者在术前进行乙肝表面抗原(HBs Ag)、丙型肝炎病毒抗体(抗-HCV)、梅毒螺旋体抗体(抗-TP)、人类免疫缺陷病毒抗体(抗-HIV)定量检测,对其阳性的标本再用酶联免疫吸附法(ELISA)进行定性检测。结果 6212例标本中,定量检测阳性率分别为HBs Ag8.24%(512/6212)、抗-HCV阳性0.097%(6/6212)、抗-TP阳性1.92%(119/6212),查出1例抗-HIV1/2阳性标本,经ELISA法检测也为阳性,再送HIV确证实验室确证为阳性。两种方法 HBsAg检测阳性率差异有统计学意义(χ~2=345.8,P<0.001)。抗H-CV和抗-TP检测阳性率差异无统计学意义。结论术前四项定量检测可发现低浓度的标本,降低漏诊率,对加强医护人员的自我保护和防范意识,减少职业暴露的风险和医源性感染具有重要意义。
