Name/Description
Formula
URNaEx mmol/24h Urine sodium excretion URNaEx (mmol/24h) = URNa
(mmol/L) × Urine (ml/24h)/1000
URKEx mmol/24h Urine potassium excretion URKEx (mmol/24h) = URK
(mmol/L) × Urine (ml/24h)/1000
Na/K % Sodium potassium ratio Na/K (%) = URNa (mmol/L)/URK
(mmol/L) × 100
CNa ml/24h Clearance of sodium CNa (ml/24h) = URNa (mmol/L) ×
Urine (ml/24h)/SerNa (mmol/L)
CCr ml/min Creatinine clearance rate CCr (ml/min) = UCr (μmol/L) ×

FENa % Fractional excretion of
sodium
FENa (%) = [URNa (mmol/L) × SCr

FEUr % Fractional Excretion of
Urea
FEUr (%) = [SCr (μmol/L) × UUN
