What is Protein Creatinine Ratio?
The protein creatinine ratio calculator helps assess kidney function by measuring protein levels in urine. This vital medical tool detects proteinuria, indicating potential kidney damage. Essential for monitoring diabetic patients and hypertension cases, it provides quick results for early intervention. Regular checks help prevent chronic kidney disease progression. Healthcare professionals use this ratio for accurate diagnosis and treatment planning.
PCR Calculator
| Ratio (mg/g) | Interpretation |
|---|---|
| <150 | Normal |
| 150-500 | Microalbuminuria |
| >500 | Macroalbuminuria |
Calculation Formula
Protein Creatinine Ratio (PCR) = (Urine Protein in mg/dL) / (Urine Creatinine in mg/dL) × 1000
How to Use
Enter protein and creatinine values from your urine test results. Our calculator instantly computes the ratio, classifying results into normal, microalbuminuria, or macroalbuminuria. Save time on manual calculations while ensuring accuracy. Regular monitoring helps track kidney health effectively. Always consult your doctor for clinical interpretation and next steps.
Derivation Process
The protein-creatinine ratio was developed to simplify 24-hour urine protein tests. Researchers found strong correlation between random spot PCR and daily protein excretion. Approved by nephrology associations, it reduces collection errors and improves patient compliance. Standardized through clinical trials involving thousands of patients worldwide.
