What Sodium measures
Sodium is the main electrolyte in blood and reflects the balance of salt and water in the body.
If your Sodium is low
Sodium below the range usually reflects extra water relative to salt, which can follow high fluid intake, some medications or illnesses.
Commonly associated with
- High fluid intake
- Diuretics and other medications
- Hormonal factors
- Illness with vomiting or diarrhea
If your Sodium is high
Sodium above the range usually reflects too little water relative to salt, as with dehydration.
Commonly associated with
- Dehydration
- High salt intake
- Certain medications
Typical reference range
| Group | Typical range |
|---|---|
| Adults | 134 – 144 mmol/L |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your sodium is within the range printed by your lab.
