In water-electrolyte imbalance, Fractional excretion of uric acid (FEUA) is defined as fraction of uric acid filtered by the kidneys that is then excreted by the kidneys.
The normal values are:
A value of 4% for less suggests prerenal causes of hyponatremia[2].
If the FEUA is high (higher than 11%), this suggests SIADH, thiazide-induced hyponatremia, or renal salt wasting[2].
