What is the normal range for HCO3- in mEq/L?

The normal range for bicarbonate (HCO3-) in milliequivalents per liter (mEq/L) is generally accepted to be between 22 and 26 mEq/L. This range is considered critical for assessing acid-base balance in the body, as bicarbonate is an essential buffer that helps maintain pH levels within a narrow range, which is vital for normal physiological function.

Maintaining bicarbonate levels within this range allows the body to effectively manage metabolic processes and counteract any excess acids that may be produced. If HCO3- levels fall outside of this normal range, it could indicate metabolic acidosis (if too low) or metabolic alkalosis (if too high), each associated with different clinical conditions that could require further investigation or intervention. Thus, understanding the normal range aids healthcare professionals in diagnosing and treating various metabolic disorders.
