Urine glucose in routine urine tests is helpful in the diagnosis of diabetes. Normally, urine glucose is negative, and when blood glucose is elevated it can appear positive, and with the degree of elevation of blood glucose, urine glucose can be expressed as (+) to (++++). However, the diagnosis and control of diabetes still needs to be determined by blood glucose, because when the renal glucose threshold decreases, a positive urine sugar may occur despite a low blood glucose level. Other common indicators in urine routine are: i. Ketone bodies, mainly used to determine whether there is diabetic ketosis, which is an acute complication of diabetes and can occur in severe cases of diabetic ketoacidosis. Urine protein, when the presence of urine protein should be considered combined with diabetic nephropathy or primary kidney damage, further examination is required. Third, urine red blood cells and occult blood, white blood cells and other indicators, mainly used to determine the urinary tract infection, the number of red blood cells and other indicators.
