常规尿液检验与生化检验对诊断糖尿病的价值分析

Value of Routine Urine Test and Biochemical Test in the Diagnosis of Dia⁃betes Mellitus

目的探讨常规尿液检验与生化检验对诊断糖尿病(diabetes mellitus,DM)的价值。方法选取2023年1月—2024年1月福清市第二医院收治的80例疑似DM患者,以口服葡萄糖耐量试验为金标准,均接受常规尿液检验及生化检验,比较两种检验方法诊断结果、诊断效能(灵敏度、特异度、准确度、阳性预测值、阴性预测值)。结果80例疑似DM患者中,确诊DM患者47例,非DM患者33例;生化检验诊断的灵敏度为82.98%(39/47),特异度为78.79%(26/33),阳性预测值为84.78%(39/46),阴性预测值为76.47%(26/34),准确度为81.25%(65/80),高于常规尿液检验的53.19%(25/47)、48.48%(16/33)、59.52%(25/42)、42.11%(16/38)、51.25%(41/80),差异有统计学意义(χ^(2)=9.596、6.548、7.062、8.719、16.101,P均<0.05)。结论生化检验较常规尿检验结果更准确,对DM的诊断价值更高。

Objective To explore the value of routine urine test and biochemical test in the diagnosis of DM.Methods A total of 80 suspected DM patients admitted to the Second Hospital of Fuqing from January 2023 to Janu-ary 2024 were selected.All suspected DM patients were underwent routine urine and biochemical tests and oral glu-cose tolerance test was used as the gold standard.The diagnostic results,diagnostic efficacy(sensitivity,specficity,accuracy,positive predictive value and negative predictive value)in both testing methods were compared.Results Among 80 suspected DM patients,47 cases were diagnosed with DM and 33 were non DM patients.The sensitivity of biochemical test was 82.98%(39/47),specificity was 78.79%(26/33),positive predictive value was 84.78%(39/46),negative predictive value was 76.47%(26/34),and accuracy was 81.25%(65/80),respectively,which were higher than 53.19%(25/47),48.48%(16/33),59.52%(25/42),42.11%(16/38),and 51.25%(41/80)of routine urine test,respec-tively,and the differens were statistically significant ruine tests(χ^(2)=9.596,6.548,7.062,8.719,16.101,all P<0.05).Conclusion Biochemical test is more accurate than routine urine test and has higher diagnostic value for DM.
