A magnesium levels blood test measures the amount of magnesium in your blood. Magnesium is a mineral that helps muscles, nerves, and the heart work properly. This test is ordered when a doctor suspects your magnesium level is too high or too low, often due to kidney problems, digestive issues, or certain medications.

What it measures

  • Total Magnesium — The main measurement of magnesium in your blood.
  • Ionized Magnesium — The active form of magnesium, sometimes measured separately.
  • Albumin — A protein that binds magnesium; may be checked to interpret total magnesium.

Who it is for

Doctors typically order this test for people with symptoms of magnesium imbalance, such as muscle cramps, weakness, irregular heartbeat, or fatigue. It may also be ordered if you have kidney disease, take certain diuretics, or have long-term digestive problems.

Preparation

Usually no special preparation is needed. You can eat and drink normally unless your doctor tells you otherwise. Some medications can affect magnesium levels, so tell your doctor about all medicines you take.

Results and what they mean

Results are reported as a number in milligrams per deciliter (mg/dL). Your doctor will interpret the result based on your health history and other tests. A low or high result does not always mean a problem, and only a clinician can determine what it means for you. This is general information, not medical advice.
