- A sample
collected in a sterile plastic 24-hour urine container is required.
- On the chosen
day, the first urine of the morning will be discarded. From that moment, the
urine emitted throughout the day will be collected, including the first urine
of the following morning.
- All urine passed
during the 24 hours should be collected. If it is estimated that more will be
urinated from the container, more containers should be obtained.
