Abstract： Objective To analyze the value of blood glucose test and urine glucose test in diabetic patients.Methods A total of 80 patients with suspected diabetes mellitus admitted to the Third Hospital of Fuqing from June 2021 to January 2022 were selected as the study objects.Blood glucose and urine glucose were tested,and the results of clini-cal comprehensive analysis were the gold standard.The diagnostic values of blood glucose test and urine glucose test were analyzed.Results 64 cases were confirmed positive by comprehensive diagnosis,and the positive detection rate of diabetes was 80.00%.The positive rate of diabetes in urine glucose test was 70.00%,the positive detection rate of diabetes by blood glucose test was 80.00%,and the positive detection rate of blood glucose text was significantly higher than that of urine glucose text,and the difference was statistically significant(χ2=6.533,P=0.011).The sensitiv-ity,specificity and accuracy of blood glucose test were significantly higher than that of urine glucose test,and the dif-ferences were statistically significant(all P<0.05).Conclusion Blood glucose test is more valuable than urine glucose in the diagnosis of diabetes.
