Calculate and interpret Urine Protein to Creatinine Ratio (PCR) to assess the degree of proteinuria and kidney disease severity.
The Urine Protein to Creatinine Ratio (PCR) is a test used to estimate the amount of protein excreted in the urine, which helps assess kidney function and detect kidney damage.
Normal PCR values are typically less than 0.2 mg/mg (or less than 200 mg/g). Values above this range suggest abnormal protein loss in the urine (proteinuria).
Higher PCR values can indicate kidney disease, infection, or other medical conditions affecting the kidneys.
- Normal PCR: Less than 0.2 mg/mg – suggests normal kidney function.
- Mild proteinuria: 0.2 to 0.5 mg/mg – may indicate early kidney damage.
- Significant proteinuria: Above 0.5 mg/mg – often indicates kidney disease requiring further evaluation.
If your urine protein is 150 mg/dL and urine creatinine is 100 mg/dL, your PCR is calculated as 1.5 (150/100), which indicates significant proteinuria.
- PCR is a convenient alternative to 24-hour urine protein collection but may be influenced by factors like hydration status.
- Results should be interpreted alongside clinical findings and other tests.
- Consult your healthcare provider for accurate diagnosis and treatment.
