Supplies

  • 24-hour urine collection jug
    • Note: The jug may contain acid. Do not urinate directly into the urine collection jug. Use the provided urine collection transfer device to safely transfer urine into the collection jug.
  • Urine collection transfer device (fits on the rim of the toilet to enable safe transfer of urine to the collection jug)

24-Hour Collection Instructions

  1. Follow your provider’s directions regarding food, drink, or medications before and during collection.
  2. Empty your bladder completely when you get up in the morning. DO NOT SAVE THIS URINE SPECIMEN. Discard your first morning urine in the toilet. This is your START time.
  3. Record the START date and time on the collection jug label (example: 9/20/09 at 7:00 AM).
  4. For the next 24 hours, ALL urine that you pass must be transferred into the collection jug provided. Urinate into the urine collection transfer device and then carefully transfer the urine into the collection jug. Do this all day and night. Keep the collection jug refrigerated during the collection period.
  5. Urinate for the last time the next morning at the same time the collection started. SAVE THIS URINE SPECIMEN and add it to the collection jug using the urine collection transfer device. The STOP time must be the same as the START time or the collection is not considered a 24-hour urine.
  6. Record the STOP date and time on the collection jug label (example: 9/21/09 at 7:00 AM). The stop time must match the start time.
  7. Bring the specimen to the laboratory drop-off location as soon as possible after the 24-hour collection is complete.
  8. Certain testing requires a blood draw. Check with lab staff before leaving.
