Urine Cultures
A sterile container with a lid supplied in the urine collection kit must be used for urine cultures, and these specimens must be delivered to the laboratory as soon as possible after collection or refrigerated immediately. Refrigeration must be maintained until delivery of the specimen to the laboratory.
24-Hour Urine Collections
Incorrect collection and preservation of a 24-hour urine collection will cause inaccuracy in lab testing.
The 24-hour urine specimen should be submitted in a wide-mouth, chemical clean, and properly labeled urine container. The laboratory will supply the proper preservative with the container, and the container will be given to the patient prior to the collection. This preservative may consist of boric or hydrochloric acid, which may burn if it touches the skin.
Instructions to the patient:
Instructions to the patient should clearly explain the following points:
- The collection of the 24-hour urine starts with the
patient voiding (completely emptying bladder) and discarding the first urine
passed in the morning.
- Except for this first discarded urine, all of the
urine passed during that day and night, up to and including the first voiding
the following day, should be collected.
- If possible, the entire specimen should be
refrigerated during the entire collection and delivered to the laboratory as
soon as possible after completion of the collection.
- The container should be labeled with patient’s name and the time and date the collection started and ended.
