Magnesium Blood Test

The Magnesium Blood Test measures the amount of magnesium in the blood, which is a vital mineral involved in nearly all metabolic processes of the body. Most magnesium is stored in the bones and inside body cells, while a small portion circulates in blood.

Magnesium plays a critical role in:

• Maintaining normal muscle and nerve function

• Keeping heart rhythm stable

• Supporting strong bones

• Regulating blood pressure

• Controlling blood sugar levels

• Strengthening the immune system

Abnormal magnesium levels may indicate:

• Renal insufficiency or chronic kidney disease

• Uncontrolled diabetes and diabetic acidosis

• Addison’s disease

• Hypothyroidism

• Malabsorption and malnutrition

• Hypoparathyroidism

• Chronic alcoholism

This test is extremely helpful in diagnosing electrolyte imbalance and preventing complications related to heart rhythm, muscles, and nerves.

The Serum Magnesium Test is a blood test used to measure the concentration of magnesium circulating in the bloodstream. It helps evaluate electrolyte balance and is frequently ordered as part of metabolic and kidney function assessments.
