24-hour urine collection is a crucial diagnostic tool used to assess kidney function and diagnose a variety of renal and metabolic disorders. This non-invasive test measures various substances excreted in the urine over a full day. Understanding the procedure, patient preparation, and potential pitfalls is essential for nurses involved in patient care.
Preparation and Patient Education
Proper patient education is critical for accurate results. Explain the purpose of the test and the importance of collecting all urine over the 24-hour period. Advise the patient to avoid excessive physical activity and maintain a consistent diet during the collection period. Some medications may interfere with the test results, so discuss any medications with the healthcare provider.Procedure
The collection process begins in the morning. Here are the detailed steps: On the first day, the patient should urinate into the toilet upon waking and record the time.
For the next 24 hours, all urine should be collected in a special container provided by the healthcare facility.
Store the container in a cool place, preferably a refrigerator, to prevent bacterial growth.
On the second day, at the same time as the first urination, the patient should urinate once more and include this sample in the container.
Deliver the container to the laboratory as soon as possible after the final collection.
