Anion Gap Calculator
Calculate anion gap from electrolyte measurements
Note: The anion gap helps identify acid-base disorders.
Clinical judgment should always be used in conjunction with other laboratory values and patient assessment.

Anion Gap Reference Ranges
Normal Anion Gap: 8-16 mEq/L
High Anion Gap: > 16 mEq/L
Low Anion Gap: < 8 mEq/L
Formula: Anion Gap = Na+ - (Cl- + HCO3-)
High Anion Gap: > 16 mEq/L
Low Anion Gap: < 8 mEq/L
Formula: Anion Gap = Na+ - (Cl- + HCO3-)

Clinical decisions should be based on comprehensive patient assessment, including
history, physical examination, and other laboratory values. Always consider the
underlying cause of acid-base disturbances.
