FENa Calculator (Fractional Excretion of Sodium)

FENa(%)
= (Na clearance / Cr clearance) × 100
= (((Urine Na × V)/ Serum Na) / ((Urine Cr × V) / Serum Cr)) × 100
= (Urine Na × Serum Cr) / (Serum Na × Urine Cr) × 100

Serum Sodium (mmol/L) :

Serum Creatinine (mg/dL) :

Urine Sodium (mmol/L) :

Urine Creatinine (mg/dL) :




FENa ＜ 1% : Suggests Prerenal AKI
FENa ＞ 1% : Suggests Intrinsic Renal AKI
