For this test, a clean-catch (midstream) urine sample is needed. For more information, see: Urine collection - clean catch.
Some tests require that you collect all of your urine for 24 hours.
Your doctor will order certain tests, which will be done on the urine sample in a laboratory.
For detailed information about how to prepare for the test, how the test will feel, risks with the test, and normal and abnormal values, please see the test your health care provider ordered:
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your doctor about the meaning of your specific test results.
