Thoroughly wash the area around the urethra. Open a urine collection bag (a plastic bag with an adhesive paper on one end), and place it on the infant. For males, the entire penis can be placed in the bag and the adhesive attached to the skin. For females, the bag is placed over the labia. Place a diaper securely over the bag. Check your baby frequently and remove the bag after the infant has urinated into it. For active infants, this procedure may take a couple of attempts--lively infants can displace the bag, causing an inability to obtain the specimen. In children under age 3, the discovery of a urinary tract infection is very important, as it may indicate the presence of some anatomical abnormalities. In these cases, a catheterized urine sample is preferred because of greater accuracy. The urine is drained into a container for transport back to the health care provider.
