目的：对临床疑为急性胰腺炎的 ９８ 例患者，同时测定淀粉酶和脂肪酶活力，以观察它们对急性胰腺炎的诊断价值． 方法：运用临床流行病学诊断试验的方法，分别计算淀粉酶、脂肪酶及淀粉酶和脂肪酶联合对急性胰腺炎诊断的敏感度、特异度和准确度． 结果：淀粉酶对急性胰腺炎诊断的敏感度、特异度和准确度分别是 ８９．６％ ，９４０％ ，９１．８％ ；脂肪酶对急性胰腺炎诊断的敏感度、特异度、准确度分别是 ９５．８％ ，９４０％ ，９４９％ ． 淀粉酶和脂肪酶联合诊断的敏感度是１００％ 、特异度为９８０％ 、准确度是９９０％ ． 结论：淀粉酶和脂肪酶联合检测可提高诊断的阳性率和符合率．
OBJECTIVE: To determine the diagnostic value of amylase and lipase in 98 patients with clinically suspected acute pancreatitis in order to observe their diagnostic value for acute pancreatitis. Methods: Using the method of clinical epidemiological diagnostic test, the sensitivity, specificity and accuracy of amylase, lipase, amylase and lipase in the diagnosis of acute pancreatitis were calculated respectively. Results: The sensitivity, specificity and accuracy of amylase in the diagnosis of acute pancreatitis were 89.6%, 940% and 91.8% respectively. The sensitivity, specificity and accuracy of lipase in the diagnosis of acute pancreatitis Degrees were 95.8%, 94 0%, 94 9%. The combined sensitivity of amylase and lipase was 100%, the specificity was 98.0% and the accuracy was 99.0%. Conclusion: Combined detection of amylase and lipase can improve the diagnostic positive rate and coincidence rate.
