Serum electrolytes

Serum electrolytes are minerals in your blood that carry an electric charge, helping to regulate important body functions. Key electrolytes include sodium, potassium, chloride, and bicarbonate. They balance fluid levels, control nerve signals, and support muscle contractions. When electrolyte levels are too high or too low, it can cause symptoms like weakness, irregular heartbeat, or confusion. Blood tests measure these levels to assess your body's fluid balance and overall health, guiding treatment for various medical conditions. Maintaining proper electrolyte balance is essential for your body's normal function and overall well-being.
