Sodium

Electrolytes are minerals that have an electrical charge when they are dissolved in water or body fluids. You have electrolytes in your blood, urine, tissues, and other body fluids.

An electrolyte panel is often part of a routine blood screening or a comprehensive metabolic panel. The test may also be used to find out if your body has a fluid imbalance or an imbalance in acid and base levels.
