Normal
anion gap
5 - 11 mEq/L
(8 mEq/L)
What are implications of
high anion gap
?
Strongly suggests:
=
lactic acidosis
(lactate)
=
ketoacidosis
(BOH butyrate)
=
renal failure
(sulfates, phosphates)
=
ingestion of certain poisons
- salicylates (produce excess acid metabolites)
What is
anion gap
if
HCO3- decreased
and
Cl- increased
?
Normal range = 5 - 11 mEq/L
Examples:
=
gut
(laxative abuse)
=
kidney disorders
Anion Gap formula
(Be able to calculate)
Anion Gap = [
Na+
] - [
Cl-
] + [
HCO3-
]
Osmolol Gap
high osmolol gap
=
solutes present in plasma that are not normally there
strongly suggests
methanol
or
ethylene glycol intoxication
(esp. if greater than 25 mOsmol/kg)
