Step by step

  1. Start in the morning. When you wake, pass urine into the toilet as usual. Do not collect this one. Write down the exact time. This is your start time.
  2. From now on, collect every drop of urine, day and night, into the container.
  3. Next morning, at the same time as your start time, pass urine one last time and add it to the container. The collection is complete.
  4. Write your name, the start date and time, and the finish date and time on the label.
  5. Bring the container to the laboratory the same morning.

Do

  • Keep the container closed, in a cool place away from sunlight. A fridge is best.
  • Pass urine into a clean, dry jug or mug, then pour it into the container.
  • Pass urine before you pass stool, so that none is lost.
  • Drink your normal amount of fluids.
  • Take the container with you if you go out.

Do not

  • Do not throw away any liquid or powder already in the container. It keeps the urine from spoiling. It may be an acid: do not touch it and do not pass urine straight into the container.
  • Do not let stool or toilet paper get in.
  • Do not start on a day when you cannot return the container next morning.
