CREATININE – 24HRS URINE Test

The Creatinine – 24 Hours Urine Test measures the total amount of creatinine excreted in the urine over a 24-hour period. Creatinine is a waste product produced by normal muscle metabolism and is removed from the body by the kidneys. Measuring urinary creatinine over a full day helps evaluate how effectively the kidneys are filtering and eliminating waste products. This test is often performed along with a blood creatinine test to calculate creatinine clearance, which provides an estimate of the glomerular filtration rate (GFR) and overall kidney function.

The test is commonly used to diagnose and monitor kidney diseases, assess kidney function in individuals with diabetes, high blood pressure, chronic kidney disease (CKD), or acute kidney injury (AKI), and evaluate patients before certain medical treatments or surgeries. It is also used to help interpret other 24-hour urine tests, such as those measuring protein, calcium, or other substances, by confirming that the urine collection was complete and accurate.

CREATININE – 24HRS URINE Test is Recommended for Individuals:

• Individuals with suspected or diagnosed kidney disease.
• People with diabetes or high blood pressure requiring kidney function assessment.
• Patients undergoing evaluation for chronic kidney disease (CKD) or acute kidney injury (AKI).
• Individuals requiring creatinine clearance testing.
• Patients undergoing 24-hour urine protein or metabolic evaluations.
• People being monitored for kidney function before or during certain medical treatments.
• Anyone advised by a healthcare provider to assess kidney health.

FAQs

1. What is the Creatinine 24-Hour Urine Test used for?
The Creatinine 24-Hour Urine Test measures the amount of creatinine excreted in urine over 24 hours to evaluate kidney function, calculate creatinine clearance, and monitor kidney health.

2. How do I collect a 24-hour urine sample?
You must collect all urine passed during a continuous 24-hour period in the container provided by the laboratory. Following the collection instructions carefully is essential to ensure accurate results.

3. What does an abnormal 24-hour urine creatinine result indicate?
Abnormal results may indicate impaired kidney function, reduced muscle mass, dehydration, or other medical conditions affecting creatinine production or excretion. Your healthcare provider will interpret the results together with blood creatinine, eGFR, and other kidney function tests.
