Magnesium Test 425

A magnesium test helps determine the level of magnesium in your blood.

Magnesium is a mineral that plays a pivotal role by assisting in energy production, muscle contraction, nerve function, and the maintenance of strong bones. It comes into the body through the diet and is absorbed by the small intestine and colon, after which it gets stored in the bones, cells, and tissues. Normally, only about 1% of total body magnesium is present in the blood and this makes it difficult to gauge an estimate of magnesium based on blood levels alone. However, it still holds value in evaluating a person's magnesium status.

More about Magnesium

The normal range for blood magnesium level is 1.7 to 2.2 mg/dL (0.85 to 1.10 mmol/L). Normal value ranges may vary slightly among different laboratories.

Low blood levels of magnesium may indicate one or more of these possibilities:

  1. Person is not consuming enough magnesium
  2. The person is consuming sufficiently, but the body is not able to absorb it
  3. The body is excreting too much of magnesium

Increased blood levels of magnesium are not usually because to dietary sources but are usually the result of an excretion problem or excessive supplementation.
