Abstract

High anion gap (AG) metabolic acidoses can be identified by a decrease in pH, decrease in HCO3- or base excess, and an increased AG. The AG represents the difference between unmeasured cations and unmeasured anions; it increases secondary to the accumulation of anions other than bicarbonate and chloride. The most common causes of high AG acidosis are renal failure, diabetic ketoacidosis, and lactic acidosis. Severe increases in concentration of phosphorus can cause hyperphosphatemic acidosis.

Keywords: Acidosis; Anion gap; Unmeasured anions.
