🩺 Anion Gap Metabolic Acidosis: A Clinical Guide for Students
Metabolic acidosis is a common acid-base disturbance, and understanding the anion gap helps clinicians narrow the differential fast. Whether you're prepping for Step 1, rounding on internal medicine, or reviewing ABGs on the fly, this blog is your shortcut to diagnosing, remembering, and applying high-yield concepts around anion gap metabolic acidosis.
📘 What Is the Anion Gap?
The anion gap (AG) is calculated as:
AG = Na⁺ – (Cl⁻ + HCO₃⁻)
Normal AG: 8–12 mEq/L
High AG: > 12 mEq/L
Helps determine if unmeasured acids are accumulating
🔍 Causes of High Anion Gap Metabolic Acidosis
The most classic mnemonic is:
| MUDPILES | GOLDMARK |
|---|---|
| Methanol | Glycols (ethylene, propylene) |
| Uremia (renal failure) | Oxoproline (acetaminophen) |
| Diabetic ketoacidosis | L-Lactic acidosis |
| Propylene glycol | D-Lactic acidosis |
| Iron, INH | Methanol |
| Lactic acidosis | Aspirin (salicylates) |
| Salicylates (late) | Renal failure |
| Ketoacidosis |
