What does Glucose - Fasting Urine Measure?

The Glucose - fasting urine test measures the levels of glucose in urine during the period of fasting. The most common cause of high levels of glucose in the urine is diabetes. In diabetes, the way the body processes the glucose gets affected. The insulin hormone is responsible for controlling the metabolism of glucose in the blood. In diabetic patients, the body is either not able to make enough insulin or the body is not able to utilize the insulin produced. Due to this, the glucose starts to build up in the blood and the kidneys are not able to control it to release it into the urine.

The presence of glucose in the urine is termed as glycosuria or glucosuria. This could be due to side effects caused by certain medicines or problems in the kidney, such as renal glycosuria.
