How should I collect 24-hour Urine sample?
- It is very important that you collect all the urine that you pass during an exact 24-hour period. Do not void urine directly into the 24-hour container but into a suitable clean detergent-free jug and then pour into the 24-hour container.
- Ensure that the container is labeled with patient’s full name, date of birth and address, date and time collection of specimen started and finished.
- Loss of any urine, or a collection made for either more or less than 24 hours, will invalidate the test and might lead to an incorrect diagnosis.
- If this container contains acid as a preservative and/or has a warning label, then care needs to be exercised when adding urine to it from your collection vessel. The following points should also be noted: Hydrochloric Acid (fuming liquid) causes burns and is irritating to eyes, skin and respiratory system. If in contact with skin, wash immediately with plenty of water and seek medical advice. Keep out of reach of children. Not to be taken internally – would cause severe irritation and damage.
- Empty your bladder at 7am on rising (or at a more convenient time) and throw away the sample.
- Only after this sample has been passed is the collection started.
- Write start time on container label.
- Collect all your urine in the container provided on every occasion that it is passed during the following 24 hours and store refrigerated if possible.
- Empty your bladder at 7am on rising the next morning (or at the more convenient time chosen) and add this sample to the collection.
- Write the finish time on the container label.
- Please ensure that the label on the container and the request form are fully completed and that the cap is closed securely.
- Bring the collection to the hospital on the day of completion.
If you forget and lose a sample down the toilet, then please throw away all the urine collected up to that time and start again the following morning. If you are making an acid collection, return the container with the acid to the laboratory and request a new container from the laboratory.
