Protein-to-Creatinine Ratio Calculator Calculate protein-to-creatinine ratio (PCR) from urine test results. PCR > 0.2 g/g (or 22 mg/mmol) indicates significant proteinuria. Used to screen for kidney disease and monitor diabetic nephropathy. — free online calculator.

Formula

PCR = Urine Protein (mg/dL) ÷ Urine Creatinine (mg/dL)
  • Protein-to-Creatinine Ratio Calculator calculates its result from Urine Protein (mg/dL), Urine Creatinine (mg/dL). It uses the formula PCR = Urine Protein (mg/dL) ÷ Urine Creatinine (mg/dL). Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
  • The main inputs are Urine Protein, Urine Creatinine. Enter them in the units and format shown in the calculator.
  • Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Protein-to-Creatinine Ratio

Inputs
  • Urine Protein: 30 mg/dL
  • Urine Creatinine: 100 mg/dL

Using Urine Protein (mg/dL) = 30, Urine Creatinine (mg/dL) = 100, the calculated result is 0.3.
