Measures sodium, potassium, chloride, and CO2 to evaluate your body's fluid balance and acid-base status. The Electrolyte Panel measures four key minerals in your blood that carry an electric charge. These electrolytes help regulate nerve and muscle function, hydration, blood pH, and more. Imbalances can cause fatigue, muscle cramps, irregular heartbeat, and confusion. **Clinical use:** Metabolic testing evaluates how your body processes energy — looking at glucose handling, lipids, organ function, and electrolytes to detect early signs of metabolic disease. ## Who should order it? Adults wanting a comprehensive metabolic baseline, anyone with metabolic syndrome risk factors, and patients tracking response to lifestyle, GLP-1 medications, or other metabolic therapy. ## Biomarkers measured - [Sodium](https://www.test-well.com/biomarkers/sodium) - [Potassium](https://www.test-well.com/biomarkers/potassium) - [Chloride](https://www.test-well.com/biomarkers/chloride) - [CO2](https://www.test-well.com/biomarkers/carbon-dioxide) ## Price by lab | Lab | Test price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $19.99 | $25.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | Labcorp | $20.99 | $26.99 | Choose at checkout; walk-in patient service centers nationwide (not NY/NJ) | | BioReference (NY & NJ) | $24.99 | $30.99 | New York and New Jersey orders route here automatically | Rhode Island is not served.
