Protein/Creatinine Ratio, 24 Hr details
What Protein/Creatinine Ratio, 24 Hr shows
The protein/creatinine ratio is calculated by dividing the total protein in your 24-hour urine collection by the creatinine in the same collection. Creatinine is released at a fairly steady rate, so the ratio helps adjust for urine concentration and gives a check on whether the collection was complete. It is used to assess and monitor protein loss through the kidneys, for example in kidney disease, diabetes, high blood pressure or pregnancy. A higher ratio indicates more protein leaking into the urine, which can reflect kidney damage, while temporary rises can follow fever or hard exercise. It is interpreted alongside kidney function tests and repeat measurements.
Tests that include Protein/Creatinine Ratio, 24 Hr
Urinary total proteins are negligible in healthy individuals. Concentrations are increased in patients with a wide variety of diseases that impair renal function, including diabetes, hypertension, nephritic syndrome, and drug nephrotoxicity.
- Creatinine, 24 Hour Measures the total creatinine passed in a 24-hour urine collection, used to check the collection is complete and to calculate kidney function and other urine results.
- Protein/Creatinine Ratio, 24 Hr A ratio calculated from protein and creatinine in a 24-hour urine collection, used to assess how much protein your kidneys are leaking.
- Protein, Total, 24 Hr Measures the total protein passed in your urine over 24 hours, used to quantify and monitor protein loss through the kidneys.
