Are you tired of calculating Anion Gap using pen and paper? Fear not, for the Anion Gap Calculator is here to save the day! No more worrying about math mistakes or illegible handwriting. Let’s dive into the world of Anion Gap calculation!

Anion Gap Categories

Category Range Interpretation
Normal 8-16 mmol/L No acid-base disorder
High >16 mmol/L Metabolic acidosis
Low <8 mmol/L Hypoalbuminemia

Example Anion Gap Calculations

Name Sodium (mmol/L) Chloride (mmol/L) Bicarbonate (mmol/L) Anion Gap
Alice 140 100 22 18
Bob 135 105 20 10
Charlie 145 95 26 24

Anion Gap = (Sodium + Potassium) – (Chloride + Bicarbonate)

Different Ways to Calculate Anion Gap
