| Interpretation | &UGAPP " In the setting of normal anion gap metabolic acidosis a positive urine anion gap suggests reduced ammonium excretion and is consistent with type I (distal) renal tubular acidosis or hypoaldosteronism. (Ann Clin Biochem 1999: 36:408-422)" &UGAPN "In the setting of a normal anion gap metabolic acidosis a negative urine anion gap is consistent with appropriate ammonium excretion or type II (proximal) renal tubular acidosis. (Ann Clin Biochem 1999: 36: 408-422)." |
