Explain the anion gap and how it is calculated.

What will be an ideal response?


Anion gap is the relationship of the cations [sodium (Na+) and potassium (K+)] to the anions [chloride (Cl-) and bicarbonate (HCO3-)] . The normal range is 15 to 20 mEq/L when K+ is included in the calculation (10 to 14 mEq/L when K+ is excluded). When the anion gap is outside this range, electrolyte replacement may be necessary.
