A urine glucose test is a quick and simple way to check for abnormally high levels of glucose in the urine. Glucose is a type of sugar that your body requires and uses for energy. Your body converts the carbohydrates you eat into glucose. Having too much glucose in your body can be a sign of a health problem. If you don’t receive treatment and your glucose levels remain high, you can develop serious complications.
A urine glucose test is often performed to check for diabetes. In addition, known diabetics can use the urine glucose test as a way of monitoring the degree of sugar control, or efficacy of treatments.
In some cases, a urine glucose test may also be done to check for kidney problems or a urinary tract infection.
The test involves taking a sample of urine. Once the sample is provided, a small cardboard device known as a dipstick will measure glucose levels. The dipstick will change color depending on the amount of glucose in the urine. If one has a moderate or high amount of glucose in their urine, the doctor will perform further testing to determine the underlying cause.
The normal amount of glucose in the urine is 0 to 0.8 mmol/L (millimoles per liter). A higher measurement could be a sign of a health problem. It could either be diabetes, pregnancy or a kidney disorder. The doctor would then perform further blood tests to confirm the diagnosis.
