Metabolic acidosis is typically classified according to whether the anion gap (AG) is normal (ie, non-AG) or high. Non-AG metabolic acidosis is also characterized by hyperchloremia and is sometimes referred to as hyperchloremic acidosis. Calculation of the AG is thus helpful in the differential diagnosis of metabolic acidosis. [3, 5]
