Analysis of the effect of biochemical test in the diagnosis of diabetes
Objective To analyze the value of biochemical test in the diagnosis of diabetes.Methods A total of 60 diabetic patients and 20 healthy subjects were selected as the study subjects,all of which underwent routine test and biochemical tests.The diagnostic results of the two test methods were analyzed.The diagnostic efficacy(sensitivity,specificity,accuracy)and test time of the two tests were compared.The blood lipid and blood glucose levels of diabetic patients and healthy subjects were compared.Results In biochemical test,there were 55 true positive cases,15 true negative cases,5 false negative cases and 5 false positive cases;in routine test,there were 46 true positive cases,8 true negative cases,14 false negative cases and 12 false positive cases.The sensitivity,specificity and accuracy of biochemical test were 91.67%,75.00%,87.50%,91.67%and 75.00%respectively.The sensitivity,specificity,accuracy,positive predictive value and negative predictive value of routine test were 76.67%,40.00%,67.50%,79.31%and 36.36%respectively.The sensitivity,specificity,accuracy and negative predictive value of biochemical test were significantly higher than those of routine test(P<0.05).The levels of total cholesterol,triglyceride and low density lipoprotein cholesterol in diabetic patients were higher than those in healthy subjects,but the level of high density lipoprotein cholesterol was lower than that in healthy subjects,and there were differences in comparison(P<0.05).Fasting blood glucose and 2 h postprandial blood glucose(11.08±2.46)mmol/L in diabetic patients were(8.22±1.72)and(11.08±2.46)mmol/L,which were significantly higher than(5.71±1.19)and(7.50±3.12)mmol/L in healthy subjects,and there were differences in comparison(P<0.05).The test time of biochemical test was(19.34±5.34)min,which was shorter than(36.21±4.82)min of routine test,and there was a difference in comparison(P<0.05).Conclusion The diagnostic sensitivity,specificity and accuracy of biochemical test were better than those of routine test.At the same time,by testing the blood glucose and blood lipid levels,the results can prevent the complications of patients,and provide an important reference for clinical treatment,which is worthy of clinical promotion.
