A urine test is generally referred to as a routine urine test, which can be used to screen for diabetes, but cannot diagnose diabetes.
Routine urine tests can check urine sugar levels, if there is a positive urine sugar need to consider the possible occurrence of diabetes, but positive urine sugar can also be seen in a large number of high-sugar foods, or familial renal glycosuria, etc., so a positive urine sugar can only play a role in screening for diabetes, but can not be diagnosed with diabetes.
To determine the presence of diabetes should be fasting blood glucose test and glucose tolerance test and other tests. People who are found to have a positive urine glucose test are advised to go to the hospital and ask the doctor to make a judgment.
