WebNov 15, 2022 · INTRODUCTION. The fractional excretion of sodium (FENa) measures the percent of filtered sodium that is excreted in the urine. This calculation is widely used to help differentiate prerenal disease (decreased kidney perfusion) from acute tubular necrosis (ATN) as the cause of acute kidney injury (AKI, formerly called acute renal failure).

WebIn this study, FENa (>1%) had a specificity of just 54% in detecting intrinsic kidney injury. However, it is important to note that an FENa of <1% may still provide value in patients on diuretics, as noted by the high negative predictive value of 82% in this study (table 3 in the work by Abdelhafez et al. [ 4 ]).

WebCalculate the fractional excretion of sodium given the serum and urine sodium, and the serum and urine creatinine. To accurately interpret FENa, patients should not have recently received diuretics. FENa is greater than 1% and usually greater than 3% with acute tubular necrosis and severe obstruction of the urinary drainage of both kidneys.
