Tips For Diabetic Home Care and Monitoring
Urine Glucose Tests

Urine tests are not very accurate because they only record results if there is glucose in the urine and the level has to be quite high (180 mg/dL) to show up. The result usually comes up negative at levels below 180 mg/dL. As well, the results do not represent the glucose levels at the time of testing, but the time between when the sample was taken and the previous time the diabetic urinated. They are not recommended to be used to change insulin doses.
