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.

What can throw off this result
Physician-reviewed “Before your test” pages — what each factor does, for how long, and what to do about it.
An Electrolyte Panel 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.

No, fasting is not required for an Electrolyte Panel — you can eat normally and book any time of day. Stay normally hydrated.
Ibuprofen and other NSAIDs, dehydration, caffeine and keto and high-protein diets can change an Electrolyte Panel result without anything being wrong. Ibuprofen and other NSAIDs can raise Potassium and can lower Sodium — tell the clinician about NSAID use if potassium is high. Dehydration can raise Sodium — hydrate normally. Caffeine can raise Sodium — drink water; caffeine is not a substitute for hydration. Keto and high-protein diets can lower Sodium — hydrate and mention the diet if a metabolic panel is drawn in the transition. Each factor is covered on our physician-reviewed "Before your test" pages; when one applies, the fix is usually to remove it and retest.
