Objective To analyze the diagnostic value of urinary albumin,immunoglobulin G and β2 microglobulin in the diagnosis of elderly patients with diabetes.Methods Forty-five elderly patients with simple diabetes admitted to Nanjing County Hospital from January 2021 to June 2023 were selected as the simple elderly diabetes group,twenty-five elderly patients with diabetic nephropathy admitted during the same period were selected as the elderly diabetic nephropathy group,and seventy healthy patients during the same period were selected as the control group.Urinary al-bumin,immunoglobulin G and β2 microglobulin were tested in groups.The test results of the two groups were com-pared and analyzed.The various detection indexes were compared and analyzed.The specificity,sensitivity and accu-racy of urine albumin,immunoglobulin G and β2 microglobulin single and combined test methods for the diagnosis of diabetic nephropathy in the elderly were analyzed.Results The levels of urinary albumin,immunoglobulin G and β2 microglobulin in simple diabetic group and diabetic nephropathy group were higher than those in control group,the above indexes in simple diabetes group were lower than those in diabetic nephropathy group,and the differences were statistically significant(all P<0.05).The sensitivity of the three methods combined test was 92.00%,higher than that of β2 microglobulin 60.00%,and the difference was statistically significant(P<0.05).Conclusion The application of urinary protein,immunoglobulin G and β2 microglobulin in the diagnosis of diabetes in elderly patients can effec-tively determine whether patients have diabetes,with high accuracy and sensitivity,which is conducive to improving the diagnosis and detection rate of diabetic nephropathy,and evaluating the severity of patients'disease,and can be an important auxiliary diagnostic indicator.
