浓缩集菌法诊断粪便幽门螺杆菌的实用价值

Wang RuiFang Laboratory of Bacteriology

目的:探讨浓缩集菌法诊断HP的实用价值。方法:采用ELA和浓缩集菌法检查了经胃镜确诊的31例胃病患者粪便标本中的HP。结果:组织学法与ELA二者间值和比数无显著性意义P>0.05(X^2=0.0),ELA的敏感性为90％,特异性为83.3％,准确性为95％,阳性预测值为94.7％,阴性预测值为71.4％,组织学法与浓缩集菌法二者间结果比较无显著性差异P>0.05(X^2=0.0),浓缩集菌法敏感性为92％,特异性为83.3％,准确性为96％,阳性预测值为95.8％,阴性预测值为71.4％。结论:ELA与浓缩集菌法是临床诊断胃病较好的方法,浓缩集菌法更适用于基层。

Objective to study the practical values of concentration method diagnosis in stool Method HP in feces specimens of 31 patients was detected by ELA and concentration method after gastroscope makes a definite diagnosis. Results ELA was no significance than hitopogic techniques P > 0. 05 (X2 = 0. 0). The sensitivity, specificity,accuracy,positive and negative predictive. Values of ELA were 90%,83. 3%,95%,94. 7%,71. 4% respectively. The concentration method was no significance than hitologic techniques P>0. 05 (X2 = 0. 0). The sensitivity specificity accuracy positive and negative predictive values of concentration method were 92%,83%, 96%,95. 8%.71. 4% respectively. Conclusion : ELA and concentration method were better in the diagnosis of gastric diseases. Concentration method more applied to the basic level than to ELA.
