The fractional excretion of sodium (FENa) is the percentage of the sodium filtered by the kidney which is excreted in the urine. It is measured in terms of plasma and urine sodium, rather than by the interpretation of urinary sodium concentration alone, as urinary sodium concentrations can vary with water reabsorption.
FENa has traditionally been considered as lacking validity in patients on diuretics. In this study, FENa (>1%) had a specificity of just 54% in detecting intrinsic kidney injury.
15 lis 2022 · Learn how to calculate and interpret FENa, a measure of the percent of filtered sodium excreted in the urine, to help differentiate prerenal disease from acute tubular necrosis. Find out the limitations, alternatives, and novel biomarkers for FENa in AKI.
Fractional excretion of sodium (FENa) provides an accurate assessment of volume status than the urine sodium alone because it corrects for the effect of variations in urine volume on the urine sodium.
Learn how to calculate fractional excretion of sodium (FENa), a measure of kidney function, based on blood and urine tests. Find out why and how FENa is used to diagnose acute kidney disease or heart failure.
25 mar 2024 · FENa is the percentage of sodium filtered by the kidney that is excreted in the urine. Use this calculator to evaluate acute kidney failure and differentiate pre-renal, post-renal and intrinsic causes based on blood and urine tests.
