An electrolyte panel includes the evaluation of your blood levels of sodium, potassium and chloride. It may be ordered as part of a routine screening or as a diagnostic aid when you have symptoms, such as edema, nausea, weakness, confusion, or cardiac arrhythmias which might be due to an electrolyte imbalance. It is frequently ordered as part of an evaluation when you have an acute or chronic illness. Electrolyte tests are commonly used to monitor treatment of certain problems, including high blood pressure (hypertension), heart failure, and liver and kidney disease.
