The Formula Explained
The Anion Gap is calculated as:
\[ \text{Anion Gap} = \text{Na}^+ - (\text{Cl}^- + \text{HCO}_3^-) \]
\[ \text{Anion Gap} = \text{Na}^+ - (\text{Cl}^- + \text{HCO}_3^-) \]
Glossary of Terms
- Sodium (Na⁺): A key electrolyte in the blood.
- Chloride (Cl⁻): An electrolyte that helps maintain fluid balance.
- Bicarbonate (HCO₃⁻): A form of carbon dioxide in the blood.
- Anion Gap: The difference between primary measured cations and anions.
Frequently Asked Questions (FAQ)
What is the anion gap?
The anion gap is a measurement used to identify the causes of metabolic acidosis.
How do you calculate the anion gap?
The anion gap is calculated using the formula: Na⁺ - (Cl⁻ + HCO₃⁻).
Why is the anion gap important?
It helps in diagnosing the underlying cause of metabolic acidosis.
What is a normal anion gap range?
The normal range is typically between 8 and 12 mmol/L.
What does a high anion gap mean?
A high anion gap can indicate conditions such as lactic acidosis, ketoacidosis, or renal failure.
