Measurement of fractional excretion of sodium
(C0428601)
Definition (NCI_CDISC)
|
A measurement of the fractional excretion of sodium that is computed based upon the concentrations of sodium and creatinine in both blood and urine.
|
Definition (NCI)
|
The percentage of the total sodium filtered by the kidney that is excreted in the urine. The fractional excretion is calculated by multiplying urinary sodium concentration by the plasma creatinine concentration, then dividing by the urinary creatinine concentration multiplied by the plasma sodium concentration. The resulting ratio is multiplied by 100.
