Interactive Anion Gap calculator with albumin correction. Requires the calculator gadget.

Usage: {{Anion Gap Calculator}}

Anion Gap Calculator
Parameter Value
Sodium (Na⁺) mEq/L
Chloride (Cl⁻) mEq/L
Bicarbonate (HCO₃⁻) mEq/L
Albumin (g/dL) — optional, for correction
Results
Anion Gap mEq/L
Corrected AG (for albumin) mEq/L
Delta-Delta Ratio (ΔAG / ΔHCO₃)
Interpretation
AG <12 Normal anion gap — Consider non-AG metabolic acidosis (HARDUPS mnemonic).
AG ≥12 Elevated anion gap — Consider MUDPILES: Methanol, Uremia, DKA, Propylene glycol, Isoniazid/Iron, Lactic acidosis, Ethylene glycol, Salicylates.
Delta-Delta Ratio
<1 Concurrent non-AG metabolic acidosis (mixed).
1–2 Pure anion gap metabolic acidosis.
>2 Concurrent metabolic alkalosis (or pre-existing elevated HCO₃).
