Fractional Excretion of Sodium Solution

STEP 0: Pre-Calculation Summary

Formula Used

Fractional Excretion of Sodium = (Urine Sodium Concentration*Creatinine Concentration in Plasma)/(Sodium Concentration in Plasma*Creatinine Concentration in Urine)*100
FE_Na = (Sodium_urinary*Creatinine_plasma)/(Sodium_plasma*Creatinine_urinary)*100
This formula uses 5 Variables

Variables Used

Fractional Excretion of Sodium - Fractional Excretion of Sodium is the percentage of the sodium filtered by the kidney which is excreted in the urine.
Urine Sodium Concentration - (Measured in Mole per Cubic Meter) - Urine Sodium Concentration measures the amount of sodium in a certain amount of urine.
Creatinine Concentration in Plasma - (Measured in Mole per Cubic Meter) - Creatinine Concentration in Plasma is a measurement of creatinine in blood plasma.
Sodium Concentration in Plasma - (Measured in Mole per Cubic Meter) - Sodium Concentration in Plasma is the concentration of sodium present in blood plasma.
Creatinine Concentration in Urine - (Measured in Mole per Cubic Meter) - Creatinine Concentration in Urine is measures of the amount of creatinine in a certain amount of urine.

STEP 1: Convert Input(s) to Base Unit

Urine Sodium Concentration: 0.010365 Mole per Liter --> 10.365 Mole per Cubic Meter (Check conversion here)
Creatinine Concentration in Plasma: 12 Mole per Liter --> 12000 Mole per Cubic Meter (Check conversion here)
Sodium Concentration in Plasma: 3.55 Mole per Liter --> 3550 Mole per Cubic Meter (Check conversion here)
Creatinine Concentration in Urine: 13.5 Mole per Liter --> 13500 Mole per Cubic Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

FE_Na = (Sodium_urinary*Creatinine_plasma)/(Sodium_plasma*Creatinine_urinary)*100 --> (10.365*12000)/(3550*13500)*100

Evaluating ... ...

FE_Na = 0.259530516431925

STEP 3: Convert Result to Output's Unit

0.259530516431925 --> No Conversion Required

FINAL ANSWER

0.259530516431925 ≈ 0.259531 <-- Fractional Excretion of Sodium

What is Pharmacokinetics?

Pharmacokinetics is currently defined as the study of the time course of drug absorption, distribution, metabolism, and excretion. Clinical pharmacokinetics is the application of pharmacokinetic principles to the safe and effective therapeutic management of drugs in an individual patient.
