Magnesium TestElectrolytes are necessary for basic cell function and help the body perform and maintain important processes. Magnesium is an electrolyte responsible for proper muscle, nerve, and heart function, and helps to control blood pressure and blood sugar in the body. Read more
This test can help determine the amount of magnesium you have in your blood. Low levels cause a magnesium deficiency (hypomagnesemia) and is more common than high levels (hypermagnesemia). Magnesium is critical to maintain proper muscle and brain function. It also helps turn nutrients into energy at the cellular level. Health problems that may cause a magnesium deficiency include malnutrition, alcoholism, and diabetes.
When electrolytes are imbalanced, normal bodily functions are disrupted and can cause life threatening complications. By testing your magnesium levels, you and your healthcare provider may be able to better understand the cause of your symptoms and identify next steps.
