The Chlorides Serum test is a fundamental part of your health assessment. It measures the level of chloride, a critical electrolyte, in your bloodstream. Chloride works with sodium and potassium to maintain your body's fluid balance and acid-base (pH) balance. An abnormal level is a key indicator of dehydration, kidney disease, or other metabolic imbalances. This test is a standard part of our Electrolyte Panel, requiring a simple blood draw. It’s an essential check on your body's 'electrical' system, ensuring your fundamental wiring is functioning perfectly.
