Anion Gap Calculator for Interpreting Acidic Metabolic States
What the anion gap is and why it counts The anion gap is a helpful way to analyze an electrolyte panel and recognize patterns in acid-base balance . It measures the main measured cations and anions in serum chemistry , helping clinicians detect hidden acids that do not appear directly on routine lab values. In practical terms, an elevated anion gap can be an useful clue in metabolic acidosis , especially when the cause is not obvious from the first evaluation
