Which Test Should You Choose?
The choice depends on whether the concern is hydration, pH balance, or electrolyte function. Each biomarker plays a distinct role and may be prioritized differently based on clinical suspicion.
Pros and Limitations
While each test provides valuable information, it may not capture the full clinical picture on its own. Used together, they offer better insight into homeostasis and organ function.
Using Both Together
Combining these biomarkers helps identify imbalances in fluid regulation, acid-base levels, and nerve-muscle function.
When to Test
Testing is often recommended for symptoms like muscle weakness, irregular heartbeat, or signs of dehydration or acidosis.
FAQs
