Gain a thorough understanding of your kidney function and overall metabolic health with Scan4Health’s 24-Hour Urinary Creatinine Test. This gold-standard diagnostic accurately measures the amount of creatinine your body eliminates over a whole day. Because creatinine is a byproduct of muscle metabolism that is filtered solely by the kidneys, this test provides reliable insight into renal function. It can help detect or monitor kidney disease, muscle disorders, and related systemic conditions.

• Routine Preparation: No fasting is required. Maintain a regular diet and fluid intake unless your doctor instructs otherwise.
• Medication Guidance: Tell your care team about all medications, especially antibiotics, diuretics, and blood pressure drugs. Do not stop medicines without specific instructions.
• Samples: Collect all urine over a consecutive 24-hour period in the laboratory-provided container. Begin by voiding and discarding your first urine, then collect each subsequent urination—including the first one the next morning—for 24 hours.
• Storage: Keep the container refrigerated or on ice during the collection period for sample stability.
• Labeling: Record both the start and end times, and complete any forms provided for accurate reporting.
• Avoid Contamination: Inform your physician if you are menstruating or have active bleeding (hemorrhoids) during the test period.

This test measures the total amount of creatinine produced when your muscles break down creatine, which is passed into your urine over 24 hours. Creatinine is eliminated exclusively through the kidneys, so this test reflects how well your kidneys are filtering waste from the blood. The test is used to assess kidney function, help diagnose or stage chronic kidney disease, monitor those with known kidney problems, and occasionally evaluate muscle health and nutritional status. The process requires collecting your urine every time you void for 24 hours. Missed collections or errors can skew results, making accurate adherence essential. The laboratory calculates the total creatinine and compares it to blood creatinine (if ordered) for creatinine clearance—a measure of the efficiency of waste filtration in your kidneys. High or low creatinine levels can result from kidney disease, urinary tract obstruction, muscle disorders, certain medications, or extreme dietary protein intake. Doctors interpret your results alongside your medical history, symptoms, and other lab findings to create a complete clinical picture.
