Objective: To analyzed a novel commercial pancreatic amylase reagent and to identify whether its performance is acceptable for medical use of the test results. 目的:对商品化血清胰淀粉酶试剂盒进行性能评价,判断其分析性能是否满足临床要求。
Let's take a white blood count and a blood amylase test, a kind of test for acute pancreatitis. 让我们做个白细胞计数和淀粉酶试验,这是一种专为查急性胰腺炎的试验。
The clinical value of the ratio of urine amylase to urine creatinine assay and urinary trypsinogen-2 dipstick test in the diagnosis of acute pancreatitis 尿淀粉酶/尿肌酐及尿胰蛋白酶原-2诊断急性胰腺炎的评价
Conclusion Because the sensitivity and negative predictive values of urinary trypsinogen-2 are better than those of serum amylase and urine amylase, it can be used for screening test in the diagnosis of acute pancreatitis. 结论尿胰蛋白酶原-2的敏感性和阴性预期值均高于血、尿淀粉酶,可以作为急性胰腺炎诊断的筛选指标。
Conclusion The ratio of urine amylase to urine creatinie assay and urinary trypsinogen-2 test strip are useful and better than the traditional assays for the diagnosis of acute pancreatitis in the early stage. 结论尿淀粉酶/尿肌酐比值及尿胰蛋白酶原2检测是较好的早期诊断急性胰腺炎的指标。
Methods: These methods included check-up by hands, ultrasound B, puncture, amylase test and cyst radiography+ CT. 方法:检查方法包括手法检查、B超、穿刺、淀粉酶检查、囊腔造影+CT。
The sensitivity and specificity of serum amylase test were 86.2% and 84.9% respectively, and of urinary amylase test were 82.8% and 82.1% respectively. 而血淀粉酶敏感性为86.2%,特异性84.9%;尿淀粉酶敏感性82.8%,特异性82.1%。
