Protein Creatinine Ratio Calculator
Calculate urine protein creatinine ratio (UPCR) to assess proteinuria and kidney function
Calculate Protein Creatinine Ratio
Normal range: <15 mg/dL
Typical range: 20-300 mg/dL (varies with diet, body mass, exercise)
Protein Creatinine Ratio Results
Formula: UPCR = Urine Protein (mg/dL) ÷ Urine Creatinine (mg/dL)
Calculation: 0 ÷ 0 = 0.000 g/day
Clinical Reference Ranges
Ginsberg Classification
KDIGO Classification
Example Calculation
Normal Sample
Urine protein: 2 mg/dL
Urine creatinine: 120 mg/dL
UPCR: 2 ÷ 120 = 0.017 g/day
Interpretation: Normal range
Abnormal Sample
Urine protein: 100 mg/dL
Urine creatinine: 80 mg/dL
UPCR: 100 ÷ 80 = 1.25 g/day
Interpretation: Requires investigation
Clinical Significance
Early Detection
Identifies kidney disease early
Risk Stratification
Assesses cardiovascular risk
Monitoring
Tracks disease progression

UPCR values should be considered alongside clinical symptoms and other diagnostic tests.
Understanding Protein Creatinine Ratio
What is UPCR?
The urine protein creatinine ratio (UPCR) is a laboratory test that measures the amount of protein in urine relative to creatinine concentration. It's used to detect and monitor proteinuria, which can indicate kidney disease.
Why Use This Ratio?
- •More convenient than 24-hour urine collection
- •Corrects for urine concentration variability
- •Provides reliable screening method
- •Suitable for spot urine samples
Clinical Applications
Diabetes Monitoring
Early detection of diabetic nephropathy
Hypertension
Assessment of kidney damage from high blood pressure
Pregnancy
Screening for preeclampsia
Normal Values
- • Urine protein: <15 mg/dL
- • UPCR: <0.2 g/day (normal)
- • 24-hour protein: <150 mg/day
