A magnesium blood test measures the amount of magnesium in a sample of your blood. Magnesium is a mineral that you get from many kinds of foods you eat.
Check orderable catalog codes, specimen types, fasting requirements, and demographic reference ranges across laboratories.
Laboratory assay overview
Evaluate magnesium deficiency
3.7–7.0 mg/dL
Labcorp test directory, test code 080283
Laboratory assay overview
Magnesium is an essential trace element. Deficiency leads to irritability, neuromuscular abnormalities, cardiac and renal damage. Its salts are used as antacids and cathartics. Excessive amount may cause CNS depression, loss of muscle tone, respiratory and cardiac arrest.
4.0-6.4 mg/dL

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
