A chloride blood test measures the amount of chloride in your blood. Chloride is an electrolyte, which means it is an electrically charged mineral that helps regulate the balance of fluids and the acid-base (pH) balance in your body. It works closely with other electrolytes like sodium and potassium to maintain proper hydration, blood volume, blood pressure, and acid-base balance
. You get chloride mainly from salt in your diet, and your body controls chloride levels by excreting excess amounts through urine. Abnormal chloride levels can indicate various health issues such as kidney disease, heart failure, liver disease, dehydration, or acid-base imbalances. The test is often part of routine blood panels or ordered if symptoms like prolonged vomiting, diarrhea, weakness, or breathing difficulties suggest an electrolyte or fluid imbalance
. In summary, the chloride blood test helps assess your body's electrolyte and fluid balance and can aid in diagnosing or monitoring conditions affecting your kidneys, lungs, or metabolic state
