It is always suggested to consult with a doctor before taking any serious decision on the result of this app because this app provides only estimated results that need to be rechecked and confirmed by a doctor for accurate results.

Definition
Fractional excretion of sodium is the amount of salt (sodium) that leaves the body through urine compared to the amount filtered and reabsorbed by the kidney. Fractional excretion of sodium (FENa) is not a test. Instead, it is a calculation based on the concentrations of sodium and creatinine in the blood and urine.

FENa Formula
(FENa = (Urine Na/Plasma Na) ÷ (Urine creatinine/Plasma creatinine) × 100)

How to Use
