Anion Gap Calculator for Electrolyte Analysis
What Is the Anion Gap? The anion gap is a calculated value helping evaluate plasma and serum electrolytes in a basic electrolyte panel. It shows the discrepancy between the major measured cations and anions, mainly sodium on one side and chloride plus bicarbonate on the other. Because routine lab testing does not measure every charged particle in blood chemistry, the anion gap helps estimate the amount of unmeasured anions and supports assessment of
