Sodium Blood Test
The key electrolyte for fluid balance and nerve function.
This test measures the level of sodium in your blood, a vital electrolyte that helps regulate fluid balance, nerve function, and muscle contraction. It is commonly requested as part of a routine health check, when investigating symptoms such as confusion, fatigue, or swelling, or when monitoring conditions that affect hydration and kidney function. It is suitable for anyone who needs a straightforward assessment of their sodium status.
Biomarkers included
- Sodium (Serum): The primary electrolyte measured, essential for maintaining proper fluid balance and supporting normal nerve and muscle activity.
Why it matters
Sodium is crucial for keeping your body's fluids in balance and for the proper functioning of nerves and muscles. Abnormal sodium levels can indicate dehydration, overhydration, kidney problems, or hormonal imbalances. Early detection helps guide appropriate management and supports overall health.

No special preparation required.
