Evaluation on gold immunochromatography assay and chemical method in detection of occult blood in gastric juice

Abstract:

Objective：To explore the value of gold immunochromatography assay（GICA） and chemical method in the detection of oc－cult 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 coinci－dence rate can reach 95.38%. The specificity and coincidence of GICA was better than those of chemical method with statis－tically significant differences（P<0.05）. Conclusion：GICA is su－perior to chemical method in negative predictive value and diagnostic accordance. The combination of both methods can improve the accuracy of the diagnostic therapy
