In a 24-hour urine collection, what happens if any urine is missed?

• A. You must restart the process
• B. You can continue and not restart
• C. You should discard the collected urine
• D. You should collect more urine at the end

Answer: (A)

In a 24-hour urine collection, the goal is to capture all urine excreted over a full 24-hour period. If any urine is missed, the total cannot be trusted because part of the excretion history is missing. As a result, the collection is considered invalid and you need to start over with a new 24-hour collection. Begin with an empty bladder, record the start time, collect every void for the next 24 hours, and include the final void at the end. Trying to continue after a miss or adding extra urine at the end wouldn’t fix the gap and could skew the results. Restarting ensures the measurement reflects the full 24-hour period accurately.
