What is the typical extracellular concentration of chloride (Cl-) in mEq/L?

The typical extracellular concentration of chloride (Cl-) is approximately 103 mEq/L. Chloride is one of the main electrolytes found in extracellular fluid and plays a vital role in maintaining osmotic pressure and acid-base balance in the body.

This concentration is crucial for various physiological functions, including regulating fluid balance and contributing to the formation of gastric acid (HCl) in the stomach. A concentration of around 103 mEq/L reflects the normal physiological state, and any significant deviation from this value can indicate a disturbance in electrolyte balance or an underlying health issue.

Understanding the normal levels of electrolytes like chloride is essential for assessing patient health and making informed medical decisions based on laboratory results.
