摘　　要：目的　探讨氧化酶和尿素酶对幽门螺杆菌 (HP)感染的检出率和鉴别诊断。方法　采用氧化酶和尿素酶和涂片对 1738例胃病患者进行 HP检测。结果　 1738例中氧化酶试验、尿素酶试验和涂片试验阳性检出率分别为 47.41%、89.99% ,阳性预测值为 89.76 % ,阴性预测值为 95 .3% ;尿素酶试验的敏感性为 99.72 % ,特异性为 96 .0 2 % ,阳性预浊值为 95 .36 % ,阴性预测值为 9.76 % ,两者相比较各个参数间均无明显差 (P>0 .0 5 )。结论　氧化酶试验和尿毒酶试验一样对检测 HP快速有效 ,两者联合应用可提高对 HP感染诊断和鉴别诊断的准确性。Objective:In order to study the examination and differential diagnosis of helicobacter pylori(HP) infection in patients with chronic gastritis and peptic ulcer.Method:We examined the HP in 1738 cases with oxydase test and urease test and for gastrodoudenal diseases under going upper endoscopy.Results:The rusults showed that the finding rate of HP infection was 47.41%,47.18% and 45.06% respectively in oxydase test.urease test and paint slice test.The paint slice test was basic standard,The sensiive rate was 94.87%,specific rate was 89.99%,positive prediction valus was 89.76%,negative prediction valus was 95.53% in oxydase test,The sensitive rate was 99.72%,specific rate was 96.02%,positive prediction valus was 95.36%,negative prediction valus was 99.76% in urease test,Conclusions:These data suggest that urease oxydase test was fast and effect on examintion of HP as urease test,If they combination appling are raise accueracy on examination HP for diagnosis and differential diagnosis.
