24 Hour Urine Specimen
Your physician has ordered a 24 hour urine specimen for laboratory analysis. Follow these directions carefully:
- Use the bottle given to you by your physician for collection of the specimen.
- The first step in the collection process should start between 6am and 8am (before breakfast). Write the exact time you start on the bottle.
- Empty your bladder and discard this urine. Collect all other urine during the next 24 hour period.
- WARNING: Acids are used as preservatives in the collection bottle. Collect the urine in a clean drinking cup each time and add to the collection bottle. These acids are corrosive if accidentally spilled or contact is made with the skin.
- Urinate at the end of the collection period (next morning) and include this urine in the 24 hour collection.
- The entire urine specimen should be refrigerated during the collection with each specimen added during the 24 hour collection period. Urinate before a bowel movement to eliminate contamination of the specimen.
- Do not add anything except urine to the container and do not discard any urine during this collection period.
- Normal intake of fluids during the collection period is desirable unless otherwise indicated by the physician.
- Transport to your physician’s office as soon as possible after the collection period and keep the specimen cool.
- If the specimen is for a creatinine clearance, you will need your blood drawn when you bring your specimen back.
