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.
Metabolic testing evaluates how your body processes energy — looking at glucose handling, lipids, organ function, and electrolytes to detect early signs of metabolic disease.
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.

Your Electrolyte Panel results will include values for each of the 4 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–3 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
No fasting required. Stay normally hydrated.
A Electrolyte Panel test costs $19.99 at TestWell — $25.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $59.00 at Quest Health and $49.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $80.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible.
