What is the normal bicarbonate (HCO3-) range?

Explanation:
Normal bicarbonate range reflects the metabolic component of acid-base balance and is typically 22 to 26 mEq/L. Bicarbonate acts as a base that buffers carbonic acid in the blood, and the kidneys regulate its level to help keep pH stable. When HCO3- falls below 22, it suggests metabolic acidosis; when it rises above 26, it suggests metabolic alkalosis. The other ranges fall outside the standard reference interval used in most laboratories, so 22-26 mEq/L is the best standard answer.
