Magnesium is a vital mineral, which is responsible for the formation of bones, proteins, and fatty acid. Magnesium is also responsible to build new cells, and activate B vitamins in the body. It also helps in comforting muscles and forming blood clots. Magnesium is also responsible to manufacture Adenosine Triphosphate (ATP), which is the energy source for the body. Other than this, our body requires magnesium for the action and release of insulin.

Magnesium also improves our natural immunity and thus protects the cells against various diseases. Human body consists of 20-28 g of magnesium, 99% of which is found within the cells. Magnesium in the cells controls multiple enzyme systems. The greatest part of magnesium is concentrated in the bones and in the muscles and the heart. However, only 1% of magnesium is present in the fluids between the cells.

Magnesium testing is required to diagnose deficiency of calcium and potassium. It is also recommended for a person showing symptoms, such as muscle weakness, jolts, cramping, cardiac arrhythmias, and seizures. Magnesium testing also helps in monitoring kidney functions in patients with diabetes and kidney disorders. In such cases, magnesium test is required to ensure that they are not passing or retaining undue amounts of Magnesium.

Though nutritional deficiencies of magnesium are highly uncommon, but sometimes, doctors may recommend this test. At times, such deficiency occurs due to the instances of malabsorption, diarrhea, undernourishment, and alcohol addiction.

In certain cases, medications also cause the kidneys to pass Magnesium. In such situations, the patient may be recommended magnesium or calcium supplements. However, magnesium level in blood needs to be periodically checked to ensure the success of the treatment.
