Serum Electrolytes test

A Serum Electrolytes test measures the levels of 3 significant electrolytes, namely sodium (Na+), potassium (K+), and chloride (Cl-), in the body. This test evaluates your overall health and detects or monitors issues with the kidneys, nerves, or heart. It may be done as part of routine health checkups or if symptoms of electrolyte imbalance are present.
