How the Test is Performed

For this test, you must urinate into a special bag or container every time you use the bathroom for a 24-hour period.

For an infant:

Thoroughly wash the area around the urethra (the hole where urine flows out). Open a urine collection bag (a plastic bag with an adhesive paper on one end).

Check the infant often, and change the bag after the infant has urinated. Empty the urine from the bag into the container provided by your health care provider.

An active infant can cause the bag to move. It may take more than one try to collect the sample.

When finished, label the container and return it as instructed.

How to Prepare for the Test

Certain drugs can also affect the test results. Your provider may tell you to stop taking certain medicines before the test. Never stop taking medicine without first talking to your provider.

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 Mean
