It is sometimes necessary to get a urine sample from a baby to do testing. Most the time, urine is collected in the doctor’s office. A sample can also be collected at home.
To collect a urine sample from an infant:
Thoroughly wash the area around the urethra (the hole where urine flows out). Use the soap, or cleansing wipes that your health care provider gave you.
You will be given a special bag to collect the urine. It will be a plastic bag with a sticky strip on one end, made to fit over your baby's genital area. Open this bag and place it on the infant.
Put a diaper on the baby (over the bag).
Check the infant often, and change the bag after the infant has urinated. (An active infant can cause the bag to move, so it may take more than one try to collect the sample.)
Empty the urine from the bag into the container provided by your doctor. Do not touch the inside of the cup or lid. If at home, place the container in a plastic bag in the refrigerator until you return it to your health care provider.
When finished, label the container and return it as instructed.
Thoroughly wash the area around the urethra. Clean from the front to the back on a female infant, and from the tip of the penis down on a male infant.
There is no preparation for the test. If you collect the urine at home, have some extra collection bags available.
There is no discomfort.
The test is performed to get a urine sample from an infant.
Normal values depend on what tests will be performed on the urine after it is collected.
There are no major risks to the infant. Rarely, a mild skin rash from the adhesive on the collection bag may develop.
