　　　　用于诊断泌尿系统感染。肾移植后发生排斥反应时，尿中以淋巴细胞为主．因此白细胞酯酶检测呈阴性。此时，应以镜检白细胞结果为准。\\

　　1.灵敏度和特异性\\
　　灵敏度5～15／µl；特异性较强。只对粒细胞灵敏，而与淋巴细胞不发生反应。\\
　　2.干扰因素 \\
　　(1)假阳性：发生率较高，主要见于尿标本被阴道分泌物污染，也见于尿中污染甲醛、在酸性尿环境中呈红色或深色的药物或食物，如高浓度胆红素、非那吡啶等。\\
　　(2)假阴性：见于尿白细胞少于10～25／µl；尿蛋白≥5g／L、葡萄糖≥30g／L、高比重尿液，尿中含维生素c、庆大霉素、头孢菌素等。正常人尿液pH≥4.5，草酸多以草酸盐的形式存在，如尿标本中加酸化剂使尿pH≤4.4，草酸盐被还原为草酸，则酯酶反应偏低或出现阴性。\\
