尿胰蛋白酶原-2、淀粉酶在急性胰腺炎诊断中的应用评价
International Journal of Laboratory Medicine(2013)
Abstract
目的探讨血液淀粉酶、尿液淀粉酶、尿胰蛋白酶原-2联合测定在急性胰腺炎诊断中的应用价值。方法对89例急腹症患者进行尿胰蛋白酶原-2(TPGⅡ),血、尿淀粉酶联合测定,其中38例确诊为急性胰腺炎。结果 38例急性胰腺炎患者中有35例尿胰蛋白酶原-2阳性,敏感度为92.1%;51例非急性胰腺炎患者中有4例尿胰蛋白酶原-2阳性,特异度为92.1%。血AMY特异度为82.4%,敏感度为76.3%;尿AMY特异度为88.2%,敏感度为78.9%。结论尿胰蛋白酶原-2在急性胰腺炎诊断中的灵敏度和特异度均高于血、尿淀粉酶,三者同时检测能减少漏诊误诊。
