About Albumin-Corrected Anion Gap Calculator
Anion gap adjusted for low albumin. The Albumin-Corrected Anion Gap Calculator on Picscaler gives you the answer instantly in your browser, with no sign-up.
Inputs: Sodium (mmol/L), Chloride (mmol/L), Bicarbonate (mmol/L) and Albumin (g/dL). Results shown: Anion gap and Corrected anion gap.
Formula: Corrected AG = (Na - Cl - HCO3) + 2.5 x (4.0 - albumin g/dL). Low albumin lowers the anion gap and can hide a true high anion gap.
