Magnesium, RBC

Magnesium is a critical electrolyte necessary for proper muscle, nerve, heart, and bone function. While a standard serum magnesium test only measures a fraction, the Magnesium, RBC test provides a more accurate assessment by measuring the magnesium stored inside your red blood cells. Since the majority of magnesium is stored in tissues and cells, this test is often preferred for uncovering true deficiency. It is particularly valuable for individuals managing chronic stress, metabolic dysfunction, or cardiovascular concerns, offering a crucial window into your long-term magnesium status. Understanding your intracellular magnesium level supports overall health maintenance and mineral balance.
