Chloride blood test
Normal Reference Range
95 – 108 mmol/L
Test Information
In addition to serving as an indicator of acid-base balance, serum chloride changes according to the body's homeostasis of water and electrolytes. Chloride levels are generally controlled by the kidneys' function, and abnormal quantities usually indicate renal dysfunction.
Clinical Indications
• Dehydration is indicated by hyperchloraemia, which is also linked to hypernatraemia. Additionally, elevated levels are associated with respiratory alkalosis or metabolic acidosis (caused by excessive breathing).
• Hypochloraemia: Usually linked to hyponatraemia, but it can also be brought on by persistent diarrhoea, prolonged vomiting or gastric suction, emphysema, COPD, and metabolic alkalosis.
