Use Our Anion Gap Calculator

The Anion Gap Calculator estimates the difference between positively charged ions (cations) and negatively charged ions (anions) present in your blood, aiding in the evaluation of acid-base imbalances.

Calculate Anion Gap with Formula:

Anion Gap = (Na⁺) -(Cl⁻ + HCO₃⁻) or AG=[Na+]−([Cl−]+[HCO3−​])

Just input the values below:

Sodium (Na⁺):
Chloride (Cl⁻):
Bicarbonate (HCO₃⁻):

Result: Your calculated anion gap will appear instantly.

How to Calculate Anion Gap?

If you’re wondering how to calculate anion gap, it’s simple. Use this formula:

Na⁺ − (Cl⁻ + HCO₃⁻)

For example, if:

• Sodium = 140
• Chloride = 105
• Bicarbonate = 24

Then:
Anion Gap = 140 − (105 + 24) = 11

A normal anion gap is typically 8–16 mEq/L.

Clinical Significance of a High or Low Anion Gap Calculation

• Anion Gap High may indicate:
  • Lactic acidosis
  • Ketoacidosis
  • Renal failure
  • Toxic ingestions (e.g., methanol, ethylene glycol)
• Anion Gap Low may be caused by:
  • Hypoalbuminemia
  • Lab errors
  • Multiple myeloma
