Formula
URNaEx (mmol/24h) = URNa
(mmol/L) × Urine (ml/24h)/1000
URKEx (mmol/24h) = URK
(mmol/L) × Urine (ml/24h)/1000
Na/K (%) = URNa (mmol/L)/URK
(mmol/L) × 100
CNa (ml/24h) = URNa (mmol/L) ×
Urine (ml/24h)/SerNa (mmol/L)
CCr (ml/min) = UCr (μmol/L) ×
Urine (ml/24h)/[SCr (μmol/L) × 24
× 60]
CUUN (ml/min) = UUN (mmol/L) ×
Urine (ml/24h)/[BUN (mmol/L) ×
24 × 60]
FENa (%) = [URNa (mmol/L) × SCr
(μmol/L)]/[Ucr (μmol/L) × SerNa
(mmol/L)] × 100
FEUr (%) = [SCr (μmol/L) × UUN
(mmol/L)]/[UCr (μmol/L) × BUN
(mmol/L)] × 100
Cosm (ml/min) = [Uosm
(mOsm/kgH O) × Urine
2
(ml/24h)]/[Posm (mOsm/kgH
24 × 60]
CH O (ml/24h) = Urine (ml/24h) -

Uosm (mOsm/kgH O) × Urine

(ml/24h)/Posm (mOsm/kgH
U/Posm = Uosm
(mOsm/kgH O)/Posm

BUN/SCr = [BUN (mmol/L)/SCr
(μmol/L)] × 1000
