Magnesium is an essential mineral in the human body that plays a vital role in various biochemical processes, including muscle and nerve function, blood glucose control, and protein synthesis. A magnesium test is a blood test that measures the level of magnesium in a person’s blood. The test is usually ordered to help diagnose magnesium deficiency, which can cause a range of symptoms, such as muscle weakness, fatigue, and irregular heartbeat. It is also used to monitor the effectiveness of magnesium supplementation or treatment of certain medical conditions, such as kidney disease and gastrointestinal disorders. A normal magnesium level is typically between 1.7 and 2.3 milligrams per deciliter (mg/dL) in adults, and the test is generally considered safe and straightforward. However, abnormal magnesium levels can indicate underlying health problems, and additional testing may be necessary to determine the cause of the imbalance.
