Anion Gap Calculator

Calculate the anion gap from serum electrolytes to help diagnose metabolic acidosis and other acid-base disorders.

Serum Electrolytes

Sodium (Na+)

mEq/L

Normal: 136-145 mEq/L

Include potassium in calculation

Chloride (Cl-)

mEq/L

Normal: 98-106 mEq/L

Bicarbonate (HCO3-)

mEq/L

Normal: 22-26 mEq/L

Albumin

g/dL

For albumin-corrected AG (Normal: 3.5-5.0 g/dL)

Anion Gap

14.0 mEq/L

High Anion Gap

🧪Standard AG

14.0 mEq/L

📊Corrected AG

14.0 mEq/L

📈Delta Ratio

N/A
