Collecting clean void urine specimen boys (2017)

Key points below

Why does my child need to collect a clean void urine specimen?

Your child’s doctor has asked for this specimen. Everyone has bacteria on their skin.  A clean void is done to keep skin bacteria from getting into the urine.  If skin bacteria gets into the urine, the test results will not be accurate. 

How do I collect the urine? 

Gather the supplies:

When your child feels ready to urinate (pee), follow these steps:

1. Wash your hands with soap and water.

2. Take the cap off the collection cup. Do not touch the inside of the cap.  Put the cap on a clean paper towel or surface.  The inside of the cap should be facing up.  

3. Open the three towelettes. 

4. Use the wipes one at a time to clean your child’s penis. Use each wipe one time only. If your child has a foreskin, pull it back before cleaning if possible.  In young boys, you may not be able to pull the foreskin back.  Hold back the foreskin during the whole collection.

5. Clean the penis three times.  Each time, start on the tip and make circles with the wipe as you clean and work towards the base. Once the whole penis is cleaned with one wipe, use another wipe and clean the whole penis again. 

6. When the cleaning is done, ask your child to urinate (pee).  Do not stop the urine flow. Put the collection cup in position to catch the urine. Do not let the cup touch your child’s skin.

7. When the urine is collected, remove the cup. Your child may then finish urinating.

8. Put the cap tightly on the collection cup and wipe the outside of it.

9. Wash your hands with soap and water.

10. Write your child’s name, date and time on the cup.

11. If you are at the lab, give the specimen to the staff person. If you are at home, put the cup into a plastic bag.  Put it in the refrigerator.  Bring it to the lab within 8 hours. 

12. If you are not able to collect a specimen, tell the lab staff.  Your child’s doctor may ask that the specimen be collected a different way. 



Call your child’s doctor, nurse, or clinic if you have any questions or concerns or if your child has special health care needs that were not covered by this information.
