FENa is calculated in two parts—figuring out how much sodium is excreted in the urine, and then finding its ratio to the total amount of sodium that passed through (aka "filtered by") the kidney. First, the actual amount of sodium excreted is calculated by multiplying the urine sodium concentration by the urinary flow rate. This is the numerator in the equation. The denominator is the total amount of sodium filtered by the kidneys. This is calculated by multiplying the plasma s… WebCalculate the fractional excretion of sodium given the serum and urine sodium, and the serum and urine creatinine.

WebUrinary creatinine clearance, usually calculated from 24-hour urine collections, is a relatively easy method to determine GFR using the standard U×V/P clearance equation.
