Why is this test important? Magnesium is a mineral involved in many processes in the body including nerve signaling, the building of healthy bones, normal muscle contraction and heart rhythm, and helps keep blood pressure low (good for hypertension). Magnesium deficiency can irritate the nervous system and cause muscular cramps, and an excess of magnesium is dangerous and sometimes fatal.
