What is a normal anion gap range?

A normal anion gap is typically between 8 and 12 mEq/L (if potassium is not included in the calculation).

Anion Gap Calculator

Determine the anion gap from electrolyte values to help diagnose causes of metabolic acidosis.

The Anion Gap is a clinical calculation that represents the difference between measured cations (positive ions) and measured anions (negative ions) in the blood. While the body's total charge is always neutral, a 'gap' in these common measurements helps doctors identify the presence of hidden acids, which is a vital step in diagnosing the cause of metabolic acidosis.

Include potassium in calculation

Na⁺ (Sodium)

Cl⁻ (Chloride)

HCO₃⁻ (Bicarbonate)

K⁺ (Potassium)

Result

14mmol/L

Anion Gap is 14 mmol/L

Na - (Cl + HCO₃) = 140 - (102 + 24)

Na⁺ (Sodium)140

Cl⁻ (Chloride)102

HCO₃⁻ (Bicarbonate)24

K⁺ (Potassium)4

Include PotassiumNo

工作原理

The calculator subtracts the sum of Chloride and Bicarbonate from the Sodium concentration. You can optionally include Potassium in the cation sum, though most clinical protocols exclude it.

计算公式

Gap = Na⁺ - (Cl⁻ + HCO₃⁻)

计算示例

1. **DKA**: Na 140, Cl 100, HCO3 10 = **Gap 30** (Severe).
