Magnesium, RBC Blood Test

  • Item # LC080283

Assesses red blood cell magnesium levels

This test measures red blood cell (RBC) levels of magnesium, which is the best way to assess intracellular magnesium status. With the growing recognition of the need for this mineral, knowing our levels can help guide supplementation.

Magnesium plays many vital roles in preventing heart disease, controlling blood pressure, and maintaining healthy cholesterol levels. Red blood cell (RBC) magnesium is the most precise way to assess intracellular magnesium status, and has been shown to be inversely related with hypertension.


Fasting is not required for this test. Take all medications as prescribed.


If you would like to order serum magnesium, use test code LC001537.
