SODIUM (Na), URINE

Sodium Serum test, also known as Sodium Blood test, is used to measure the amount of sodium in the blood. It is used to detect abnormal sodium levels, including low sodium (hyponatremia) and high sodium (hypernatremia) levels in the blood. 

Sodium is important for efficient muscle and nerve function in the body. Sodium also helps maintain the right balance of fluids in the body.   

The body gets most of the sodium through food and beverages and is passed through the urine, stool, or sweat. 

High levels of sodium in the blood results in high blood pressure. Lack of sodium can cause symptoms such as dizziness, fatigue, nausea, or vomiting.
