Urine sugar test; Urine glucose test; Glucosuria test; Glycosuria test DefinitionThe glucose urine test measures the amount of sugar (glucose) in a urine sample. The presence of glucose in the urine is called glycosuria or glucosuria. The glucose level can also be measured in other bodily fluids using a blood test or a cerebrospinal fluid test. How the Test is PerformedAfter you provide a urine sample, it is tested right away. The health care provider uses a dipstick made with a color-sensitive pad. The color of the dipstick changes to tells the provider the level of glucose in your urine. If needed, your provider may ask you to collect your urine at home over 24 hours. Your provider will tell you how to do this. Follow instructions exactly so that the results are accurate. How to Prepare for the TestCertain medicines can change the result of this test. Before the test, tell your provider which medicines you are taking. DO NOT stop taking any medicine before talking to your provider. How the Test will FeelThe test involves only normal urination. There is no discomfort. Why the Test is PerformedThis test was commonly used to test for and monitor diabetes in the past. Now, blood tests to measure glucose level in the blood are easy to do and are usually used instead of the glucose urine test. The glucose urine test may be ordered when your provider suspects renal glycosuria. This is a rare condition in which glucose is released from the kidneys into the urine, even when the blood glucose level is normal. Normal ResultsGlucose is not usually found in urine. If it is, further testing is needed. Normal glucose range in urine: 0 to 0.8 mmol/l (0 to 15 mg/dL) The examples above are common measurements for results of these tests. Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results. What Abnormal Results MeanHigher than normal levels of glucose may occur with:
