Urine must be collected over a 24-hour period into a sterilized container.
On the first morning, discard the initial urine and note the time.
Then, collect all urine passed during the next 24 hours, including the final portion at the same time the next day.
Measure and record the total volume of collected urine.
Transfer at least 20 ml of the well-mixed sample into a single-use sterile container.
Deliver the sample to the clinic within 2 hours.
