Anion Gap
12 mEq/L
Anion Gap vs Sodium (Na+)
Formel
Anion Gap Formula
AG = Na+ - Cl- - HCO3-
Normal Range
Normal anion gap: 8-12 mEq/L (without potassium)
Albumin Correction
Corrected AG = AG + 2.5 x (4.0 - Albumin)
Low albumin can mask an elevated anion gap.
Common Causes of Elevated Anion Gap (MUDPILES)
Methanol, Uremia, Diabetic ketoacidosis, Propylene glycol, Iron/Isoniazid, Lactic acidosis, Ethylene glycol, Salicylates
Lösungsbeispiel
Na 140, Cl 104, HCO3 24, Albumin 4.0.
- 01AG = 140 - 104 - 24 = 12 mEq/L
- 02Corrected AG = 12 + 2.5 x (4.0 - 4.0) = 12
- 03Normal anion gap (8-12)
Häufig Gestellte Fragen
What is the anion gap?
The anion gap represents the difference between measured cations and anions in the blood. It helps identify the cause of metabolic acidosis.
What causes a high anion gap?
Common causes include diabetic ketoacidosis (DKA), lactic acidosis, kidney failure, and toxic ingestions like methanol or ethylene glycol.
Why correct for albumin?
Albumin is a negatively charged protein. Low albumin levels reduce the anion gap, potentially masking an acidosis. The correction adds 2.5 for each g/dL albumin is below 4.0.
