FENa and FEUrea Calculator

Serum Creatinine is required

Urine Creatinine is required


To Calculate FENa - Enter values for Urine Sodium and Serum Sodium

To Calculate FEUrea - Enter values for Urine Urea and BUN or Serum Urea

To Calculate Both - Enter values for all fields

Fractional Excretion of Sodium (FENa) = [(Urine Sodium * Serum Creatinine) / (Serum Sodium * Urine Creatinine)]

Fractional Excretion of Urea (FEUrea) = [(Urine Urea * Serum Creatinine) / (Serum Urea * Urine Creatinine)]
