Sodium (Na)

About Test

The Sodium (Na) test measures the level of sodium, a key electrolyte, in the blood. Sodium is essential for maintaining fluid balance, regulating blood pressure, and ensuring proper muscle and nerve function. It works in conjunction with other electrolytes, such as potassium and chloride, to help regulate the body's fluid levels and acid-base balance.

This test is often included in an electrolyte panel and is used to assess overall electrolyte balance and kidney function. Abnormal sodium levels, whether too high (hypernatraemia) or too low (hyponatraemia), can indicate various health conditions such as dehydration, kidney disease, heart failure, or hormonal imbalances.

Regular monitoring of sodium levels is important for managing conditions that affect fluid and electrolyte balance. It allows healthcare providers to make informed decisions about treatments, such as adjusting medications or dietary recommendations, to maintain healthy sodium levels and support overall health and well-being.
