Term Description

The fractional excretion of sodium is calculated as follows, where the asterisk is being used to indicate multiplication: 100 * (urine Na * plasma creatinine)/(plasma Na * urine creatinine). Fractional excretion of sodium is used to try to distinguish pre-renal azotemia (FE Na <1% ) from m actute tubular necrosis (FE Na > 1%) and post renal azotemia (FE Na > 4%).

Part Description

LP64200-6   Fractional excretion of sodium
The fractional excretion of sodium (FENa) is a measure of the percentage of sodium excreted in the urine versus the sodium reabsorbed by the kidney. 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 resorption. Therefore the urinary and plasma concentrations of sodium must be compared to get an accurate picture of renal clearance. In clinical use, the fractional excretion of sodium can be calculated as part of the evaluation of acute renal failure.
