Timed Urine Sample

A sample of urine collected over a specified period of time; for a short collection (2 hours), you may be asked to do this at the laboratory. For longer collections (such as 12 hours or 24 hours), you will do this at home. At the beginning of the time period, empty your bladder and discard that urine. Note the time. Collect all urine voided for the specified period of time in the container provided. At the end of the time period, empty your bladder and ADD this urine to the container. Note the time. Bring all of the urine collected to the lab or doctor's office. If you miss collecting one or more voids, consult your doctor or the laboratory for further instructions. (See 24-hour urine sample)
