Ammoniuria
Definition
The urinary excretion of ammonia or ammonium ions, representing an essential clinical indicator of how the kidneys regulate systemic acid-base balance. In states of metabolic acidosis, its values increase significantly due to the amplification of compensatory renal ammoniogenesis, transforming ammonium excretion into a physiological barrier against blood pH decrease.
