What Does Your Chloride Blood Test Tell You?

But combined with other tests on a blood panel, it can give important clues about the balance of fluids and acids in the body. If your chloride level is off, there could be an underlying condition that needs treatment. For most laboratories, a normal chloride test result is between 96 and 106 mEq/L or mmol/L.
