Magnesium Mg Blood Test

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.

A wide variety of foods contain small amounts of magnesium, especially green vegetables such as spinach, and most magnesium in the body comes from dietary sources. The body maintains magnesium levels in its blood, cells, and bone by regulating how much it absorbs from the intestines and by how much it excretes or conserves in the kidneys.

What is being tested? The Magnesium blood test measures the amount of magnesium in your blood. Normally, only a very small amount (about 1%) of total body magnesium is present in the blood.

Magnesium is a mineral that is found in every cell of your body. It is vital to energy production, muscle contraction, nerve function, and maintenance of strong bones. About half of the body's magnesium is combined with calcium and phosphorus to form bone.
