中文摘要:
      目的:浅析免疫金标法(gold immunochromatography assay,GICA)与化学法检测胃液隐血的方法学评价。方法:以我院2012年1月至2013年1月胃液隐血检测的311例患者为研究对象,对其送检的胃液或呕吐物同时行GICA和化学法检查。结果:GICA、化学法的阳性预测率、阴性预测率、诊断符合率分别为64.73%、100%、79.74%,70.00%、53.09%、65.59%;两者联合诊断时诊断符合率可达95.38%。结论:GICA的阳性预测值与化学法并无统计学差异,但阴性预测值、诊断符合率明显优于化学法。可通过两法联合诊断来提高检测结果准确性。
英文摘要:
      Objective:To explore the value of gold immunochromatography assay and chemical method in the detection of occult blood in gastric juice. Methods: Totally 311 patients were taken as test samples. Chemical method and GICA were used to detect the gastric juice and vomits. Results: The positive predictive rates of GICA and chemical method were 64.73% and 100%; the negative predicative rates of GICA and chemical method were 79.74% and 70%; diagnostic accordance rates of GICA and chemical method were 53.09% and 65.59%.The combined diagnosis coincidence rate can reach 95.38%. The specificity and coincidence of GICA was better than those of chemical method with statistically significant differences (P<0.05). Conclusion: GICA is superior to chemical method in negative predictive value and diagnostic accordance. The combination of both methods can improve the accuracy of the diagnostic therapy
