Does this test have other names?
What is this test?
A urine glucose test is used to find out if your levels of blood sugar (glucose) are
within a healthy range. It may be used to monitor both type 1 and type 2 diabetes.
Your kidneys get rid of the extra glucose in your urine if your blood glucose rises
above normal. That's why a urine glucose test may help to find out if your blood glucose
is too high.
A urine test for glucose is easier to do than a blood test, but it's not as accurate.
Urine tests are usually used only when blood testing for glucose is difficult or can't
Why do I need this test?
You may need this test if you have symptoms of diabetes. These include increased thirst,
unexplained weight loss, increased pee, tiredness, blurred vision, or sores that don't
heal. Sometimes people with prediabetes or diabetes don't have any symptoms.
Your healthcare provider may check your glucose levels if you have risk factors for
diabetes. These include:
Being overweight or obese
Not getting much exercise
Having high blood pressure
Having high cholesterol
Having a family history of diabetes
If you don't have these risk factors, you should also be checked for diabetes beginning
at age 45. You should get checked every 3 years as long as your results are normal.
If you are pregnant and are at risk of developing gestational diabetes, you may be
screened often during and after your pregnancy.
What other tests might I have along with this test?
A urine glucose test may be done along with more sensitive and accurate blood tests.
A urine test alone is not typically used to screen for or diagnose diabetes. Other
tests that are used to screen for or diagnose diabetes or monitor blood glucose include
blood glucose and A1c blood testing. Because heart health is so closely tied to diabetes,
regular checks of blood pressure, cholesterol, and triglycerides are important, too.
What do my test results mean?
Test results may vary depending on your age, gender, health history, and other things.
Your test results may be different depending on the lab used. They may not mean you
have a problem. Ask your healthcare provider what your test results mean for you.
Urine glucose testing involves checking the color of a test strip to see if your glucose
is too high. Depending on the results, you may have blood sugar problems that need
more testing or management.
How is this test done?
A healthcare provider will usually test your urine glucose only if a blood test can't
If you need to self-monitor urine glucose levels, your healthcare provider will likely
give you test strips or tell you which ones to buy. Self-monitoring urine glucose
levels involves holding a test strip under a stream of pee. Or you may place a test
strip into a sample of pee you collect. After a set amount of time, you check the
color of the urine strip to figure out your glucose levels.
Does this test pose any risks?
The test poses no known risks.
What might affect my test results?
Urine glucose tests are not as accurate as blood glucose tests. Many things can cause
false positives or false negatives. For instance, the test actually reflects what
your blood glucose level was a few hours earlier, so it might not be very accurate.
Other factors that can affect your test results include certain medicines and vitamin
C. Even the light that the test strip is checked under can lead to a false reading.
Because of all these issues, a blood glucose test is done whenever possible.
How do I get ready for this test?
You don't need to prepare for this test. Your healthcare provider will give you specific
instructions on when to collect or test your urine and what to do before and after
each collection. Be sure your healthcare provider knows about all medicines, herbs,
vitamins, and supplements you are taking. This includes medicines that don't need
a prescription and any illegal drugs you may use.
