Anion Gap

OVERVIEW Anion Gap = Na+ – (Cl- + HCO3-) The Anion Gap (AG) is a derived variable primarily used for the evaluation of metabolic acidosis to determine the presence of unmeasured anions The normal anion gap depends on serum phosphate…

Normal Anion Gap Metabolic Acidosis

Normal Anion Gap Metabolic Acidosis (NAGMA). HCO3 loss and replaced with Cl- -> anion gap normal. if hyponatraemia is present the plasma [Cl-] may be normal despite the presence of a normal anion gap acidosis -> this could be considered a 'relative hyperchloraemia'.

Metabolic Acidosis Evaluation

A metabolic acidosis is a process which, if uncorrected, would lead to an acidaemia. It is usually associated with a low bicarbonate concentration (or total CO2), but an acidosis may be masked by a co-existing metabolic alkalosis.
