The Sodium (Na⁺) – Body Fluid test is used to measure the concentration of sodium in various body fluids such as pleural fluid, peritoneal fluid (ascitic fluid), synovial fluid, or other collected fluids.
Sodium is a vital electrolyte that helps regulate fluid balance, nerve function, and cellular activity. Measuring sodium levels in body fluids can provide important information about the underlying cause of fluid accumulation or disease.
Abnormal sodium levels in body fluids may indicate infections, inflammation, kidney disorders, or metabolic imbalances.
