What is RBC Magnesium?

The RBC Magnesium test measures the amount of magnesium inside your red blood cells, providing a more accurate long-term assessment of your body's magnesium stores. This is often preferred over serum magnesium for evaluating chronic deficiencies.

Why is this test important?

Magnesium is crucial for muscle and nerve function, blood sugar control, and blood pressure regulation. This test helps diagnose chronic magnesium deficiency, which can contribute to fatigue, muscle cramps, heart rhythm abnormalities, and other health issues.
