Description

The Serum Electrolytes panel measures sodium, potassium, and chloride to assess hydration status, acid‑base balance, nerve conduction, and cardiac rhythm. Abnormalities can result from dehydration, kidney disease, medications (diuretics), vomiting, or diarrhea. This test is frequently ordered in emergencies, hypertension follow‑up, and chronic disease management. Results guide fluid therapy and medication adjustments. No fasting is required.
