Diagnostic Blood Test:

Magnesium, RBC

Magnesium is a mineral and electrolyte essential for many important body processes, including controlling blood pressure, maintaining healthy blood sugar levels, and supporting healthy function of the nerves, muscles, bones, and heart. Abnormal magnesium levels may help explain symptoms like low energy levels, muscle cramps, heart palpitations, and breathing problems.

This test is a measure of magnesium within red blood cells, and a more accurate marker of magnesium deficiency.
