The 24 hrs urinary protein-creatinine ratio test is performed to screen for excessive proteins excreted in the urine in 24 hours to monitor kidney function. Creatinine protein is a byproduct of muscle metabolism and is normally released into the urine at a constant rate.

SPECIMEN: 10 mL (5 mL min.) aliquot of 24-hour urine. Refrigerate during collection. Record 24-hour volume on test request form and urine container.
STABILITY: Room: 6 hrs; Refrigerated: 72 hrs; Frozen: 1 week
REPORT: Daily
USAGE: Urinary Total Proteins are negligible in healthy adults. Urine Protein-Creatinine ratio is a simple & convenient method to quantitate & monitor proteinuria in adults with Chronic kidney disease.
