A normal urine sugar count is between 0 and 15 milligrams per deciliter, according to MedlinePlus. In general, glucose is not present in urine, so further testing is required if glucose is detected.
Higher than expected levels of glucose in the blood can be due to diabetes, preganancy, or renal glycosuria, which is a condition in which the kidneys release glucose into the urine, says MedlinePlus. Different labs may use different methods to test for glucose in the urine, so each lab has its own normal range. When receiving lab results, it is important for a person to discuss the specifics of the results with the doctor.
