葡萄糖尿试验

定义

The 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.

Glucose level can also be measured in other bodily fluids using a 血液测试 或者一个 cerebrospinal fluid test.

选择的名字

Urine sugar test; Urine glucose test; Glucosuria test; Glycosuria test

How the Test is Performed

After 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 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 Test

Certain 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 Feel

The test involves only normal urination. There is no discomfort.

Why the Test is Performed

This test was commonly used to test f或者一个nd monitor diabetes in the past. 现在, 血液测试s to measure glucose level in the blood are easy to do and are used instead of the glucose urine test.

The glucose urine test may be ordered when the doctor 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.

正常的结果

Glucose 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 health care provider about the meaning of your specific test results.

What Abnormal Results Mean

Higher than normal levels of glucose may occur with:

• 糖尿病: Small increases in urine glucose levels after a large meal are not always a cause for concern.
• Pregnancy: Up to half of women have glucose in their urine at some time during pregnancy. Glucose in the urine may mean that a woman has gestational diabetes.
• Renal glycosuria: A rare condition in which glucose is released from the kidneys into the urine, even when blood glucose levels are normal.

风险

There are no risks with this test.
