Feurea — free online calculator.
Formula
- Feurea calculates its result from Urine Urea (mg/dL), Plasma Creatinine (mg/dL), Plasma Urea (mg/dL), Urine Creatinine (mg/dL). It uses the formula FEUrea = (Urine Urea × Plasma Creatinine) / (Plasma Urea × Urine Creatinine) × 100. Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Urine Urea, Plasma Creatinine, Plasma Urea, 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: Feurea
- Urine Urea: 500 mg/dL
- Plasma Creatinine: 1 mg/dL
- Plasma Urea: 20 mg/dL
- Urine Creatinine: 100 mg/dL
Using Urine Urea (mg/dL) = 500, Plasma Creatinine (mg/dL) = 1, Plasma Urea (mg/dL) = 20, Urine Creatinine (mg/dL) = 100, the calculated result is 25.
