Why is Anion Gap important?

Anion gap is crucial for diagnosing metabolic acidosis and identifying its underlying cause. A high anion gap indicates accumulation of acids (ketoacidosis, lactic acidosis, toxic ingestions, renal failure). It helps differentiate between various causes of acid-base disturbances and guides treatment decisions.

What are the symptoms of abnormal Anion Gap levels?

High anion gap: Rapid breathing (Kussmaul respirations), confusion, nausea, vomiting, fatigue, abdominal pain. These symptoms reflect the underlying condition causing the acidosis.

The Anion Gap measures the difference between measured cations (sodium, potassium) and measured anions (chloride, bicarbonate) in blood, indicating unmeasured anions.

High anion gap: Diabetic ketoacidosis (DKA), alcoholic ketoacidosis, lactic acidosis, kidney failure, toxic ingestions (methanol, ethylene glycol, salicylates).
Low anion gap: Hypoalbuminemia, multiple myeloma, lithium toxicity, laboratory error.

This is a calculated biomarker derived from other test results in your panel. It provides additional clinical insights by combining multiple measurements into a single meaningful ratio or index.
