Description: • Most often, the urine is often obtained from a voided specimen.
• In children who are not toilet trained, a urine collection device, such as a bag, is placed over the genitalia, and the urine is cultured from the bagged specimen.

• Urine obtained from a urinary catheter is less invasive than a suprapubic aspiration and is less likely to be contaminated than that from a voided specimen.
