What is the normal range for HCO3 in the body?

The normal range for HCO3, or bicarbonate, in the body is essential for maintaining acid-base balance. Bicarbonate serves as a buffer, helping to regulate the pH of the blood and other bodily fluids. The correct range, from 22 to 26 mEq/L, indicates the typical concentration of bicarbonate present in the bloodstream under normal physiological conditions.

When bicarbonate levels fall outside this range, it can signify various metabolic or respiratory disorders. Lower levels may indicate metabolic acidosis, while higher levels may suggest metabolic alkalosis. Understanding the normal range helps healthcare providers diagnose and manage these conditions effectively.

In contexts where other ranges are presented, they do not represent the typical physiological values for bicarbonate in the human body, which reinforces the importance of recognizing the standard range for proper clinical assessment.
