Sodium vs Potassium: Key Differences Explained
Compare Sodium and Potassium to learn which marker is more relevant for health assessment.
Why Compare Sodium and Potassium?
Comparing Sodium and Potassium is crucial because they are often used to assess similar yet distinct health conditions. Understanding their differences helps in selecting the right test and interpreting the results accurately.
Sodium vs Potassium: Which Biomarker Matters?
Sodium and Potassium are essential biomarkers used to evaluate different health conditions. Knowing when and how to interpret these biomarkers can significantly impact clinical decision-making.
Quick Comparison Table:
Biomarker | Purpose | Ideal Range | When to Test | Key Differences |
|---|---|---|---|---|
Regulates fluid balance | 135-145 mmol/L | Assess electrolyte balance | Low levels indicate hyponatremia | |
Maintains muscle and nerve function | 3.6-5.2 mmol/L | Evaluate electrolyte disturbances | High levels indicate hyperkalemia |
Key Takeaways:
Sodium regulates fluid balance; potassium is critical for heart and muscle function.
Imbalances may lead to dehydration, cramps, arrhythmias, or fatigue.
Use both to monitor electrolyte status and kidney or adrenal function.
