This test measures the total protein passed in urine during a timed 24-hour collection. It assesses protein loss across a day.

Understanding the test
Also called 24-Hr Urine Protein
The amount of protein excreted across a full day can help a clinician assess persistent protein in urine or follow known kidney disease.
Collecting urine across the full 24 hours lets the laboratory assess total protein excretion over a day.
A clinician may use other kidney tests and the context of the specimen to guide follow-up.
Before your sample
Use the 24-hour container provided. Discard the initial urine and record its time. Collect every subsequent void and include the final one exactly 24 hours later. Report a missed portion and confirm storage requirements.
Collect urine across the 24-hour period specified by the laboratory. Record the start and finish times. If any urine is missed, let the team know before returning the container.

An incomplete collection can underestimate loss. Interpretation uses the total over the recorded period and, where relevant, kidney function and urine findings.

Bring the exact collection period and mention any missed urine. Ask whether the result represents a change from earlier complete collections.
Patient questions
The amount is interpreted over the collection period. An incomplete day or a missed specimen can alter the calculated daily loss.
Fever or strenuous exercise can temporarily raise urine protein. Tell the team if you are ill, have urinary symptoms or are menstruating. They can advise whether to collect as planned and how to interpret the result, especially if the test was requested urgently.
Urine left warm allows bacteria to grow and some components to break down, which distorts the measurement. A closed, cool container preserves the sample across the collection period.
