Anion Gap • Represents unmeasured anions in plasma such as, lactate, ketoacids, phosphate, and other organic anions. • It is used mainly in diagnosing different causes of metabolic acidosis
Anion Gap • An increase in the AG is most often due to increase in unmeasured anions • Thus, the presence of a high anion gap should result in a search for conditions that lead an excess of these substances.
Anion Gap • Plasma anion gap = ( [Na+]) - ( [Cl-]+[HCO3-] ) = 138.0 – (108.0 + 10.0) = 20meq/L NV = 8 -16 meq/L
