What is the normal range for Chloride?

• A. 95-105
• B. 85-95
• C. 100-110
• D. 90-100

Answer: (A)

Chloride is a major extracellular anion that works with sodium to maintain fluid balance and acid-base status; it often tracks with bicarbonate and total body water. The normal serum chloride range is about 95–105 mEq/L, which is the window most labs use as the reference for a typical adult. This range is centered around where chloride balance with sodium and bicarbonate stays stable, so values within it generally indicate no acute chloride disturbance. If chloride falls below or rises above this range, it points to an imbalance that often pairs with changes in acid-base status or fluid balance. For example, high chloride (hyperchloremia) can occur with excess saline administration or dehydration, while low chloride (hypochloremia) can accompany vomiting, NG suction, diuretics, or certain metabolic alkaloses. In practice, clinicians interpret chloride alongside bicarbonate and other electrolytes to assess the overall acid-base and volume status. So the best choice is the 95–105 mEq/L range because it matches the widely accepted reference interval used in clinical practice.
