The Serum Sodium test measures the level of sodium in the blood, an essential electrolyte that helps regulate fluid balance, nerve function, and muscle activity in the body. Sodium plays a key role in maintaining proper hydration and supporting normal cellular functions.
Abnormal sodium levels can indicate various health conditions. Low sodium levels (hyponatremia) may be seen in conditions such as dehydration, kidney disorders, heart failure, or excessive fluid intake, and can cause symptoms like confusion, weakness, or seizures. High sodium levels (hypernatremia) are often associated with dehydration, excessive salt intake, or certain hormonal imbalances, leading to symptoms like thirst, irritability, or neurological changes. Doctors commonly recommend this test as part of routine check-ups or when evaluating fluid and electrolyte balance.
The Serum Sodium test is simple and requires a small blood sample. Accurate results help doctors diagnose electrolyte imbalances, monitor treatment, and ensure proper management of a patient’s overall health.
