Use our Acute Tubular Necrosis (ATN) Renal Kidney Failure Index Calculator to quickly assess acute kidney injury (AKI) severity and differentiate ATN from other causes like prerenal azotemia. Input essential lab values to calculate the Fractional Excretion of Sodium (FENa) for crucial diagnostic insights and guide timely patient management decisions.

Formula:

The Fractional Excretion of Sodium (FENa) is calculated using the following formula:

FENa = (U_Na × P_Cr) / (P_Na × U_Cr) × 100

U_Na: Urine Sodium (mEq/L)
P_Cr: Plasma Creatinine (mg/dL)
P_Na: Plasma Sodium (mEq/L)
U_Cr: Urine Creatinine (mg/dL)
