The electrolyte panel is used to identify an electrolyte, fluid, or pH imbalance in the blood. 

An electrolyte panel may be ordered as part of a routine screening or as a diagnostic aid when a person has signs and symptoms, such as: 

• Fluid accumulation (edema)
• Nausea or vomiting
• Weakness
• Confusion
• Irregular heart beat (cardiac arrhythmias)

Electrolyte measurements may be used to help investigate conditions that cause electrolyte imbalances such as dehydration, kidney disease, lung diseases, or heart conditions. 

Test Includes: Carbon dioxide; chloride; potassium; sodium.
