The urine protein creatinine ratio calculator is a medical test that measures how much protein and creatinine are in your urine. It serves as a reliable indicator of kidney function — helping detect proteinuria, a condition where the kidneys leak excess protein into urine. Learn more from Cleveland Clinic about UPCR testing and why it’s done.
Instead of a 24-hour urine collection, doctors often use UPCR for quick screening and monitoring.
Why the UPCR Test Matters
A high urine protein creatinine ratio may signal early kidney damage from conditions like diabetes, high blood pressure, or chronic kidney disease. It’s also important in pregnancy monitoring for preeclampsia.
Protein in urine — also called proteinuria — can be an early indicator of kidney involvement in chronic conditions. Mayo Clinic explains proteinuria and related diagnostic testing.
How to Use the Urine Protein Creatinine Ratio Calculator
Enter two simple values:
🧪 Urine protein (mg/dL)
🧪 Urine creatinine (mg/dL)
Formula:
UPCR = Urine Protein ÷ Urine Creatinine
This gives your UPCR result quickly.
Understanding Your UPCR Result
| UPCR Result | What It Means |
|---|---|
| < 0.2 mg/mg | Normal – little proteinuria |
| 0.2 – 0.5 mg/mg | Mild protein leakage |
| 0.5 – 3.0 mg/mg | Moderate kidney damage |
| > 3.0 mg/mg | Severe proteinuria / kidney disease |
These categories are used by clinicians to assess severity and next steps.
What Causes a High UPCR?
Common causes of elevated urine protein creatinine ratio:
- Diabetes-related kidney damage
- Hypertension / high blood pressure
- Chronic kidney disease (CKD)
- Glomerulonephritis
- Preeclampsia in pregnancy
Kidneys normally prevent proteins from leaking into urine — when damaged, more protein passes through. Learn more about UPCR from the Cleveland Clinic.

When to See a Doctor
Tell your healthcare provider if:
✅ Your UPCR is above 0.2 mg/mg
✅ You have swelling, foamy urine, or fatigue
✅ You have underlying conditions like diabetes or hypertension
Persistent proteinuria requires medical evaluation to plan proper care.
