Overview

Hypochloremia (or Hypochloraemia) is an electrolyte disturbance whereby there is an abnormally depleted level of the chloride ion in the blood. It rarely occurs in the absence of other abnormalities. If it occurs together with metabolic alkalosis (decreased blood acidity) it is often due to vomiting.

Normal values of Chloride: 99-111 mEq/L (99-111 mmol/L)

Primary anion of extracellular fluid compartment; aids in maintenance of acid-base balance.
