Magnesium Blood Test

Also Known As

Mag, Mg, Magnesium-Serum

The Purpose of a Magnesium Test

Your body thrives on magnesium. It’s an important mineral that’s essential for many functions, which is why a deficiency shouldn’t be ignored. If left untreated, poor magnesium levels raise your risk for brittle bones, slow metabolism, and kidney, heart, or muscle issues, as well as serious health concerns such as heart disease, diabetes, arrhythmia, high blood pressure, and osteoporosis.

Factors that can contribute to magnesium deficiency include a poor diet, alcohol use disorder, certain medications, or diabetes, Crohn’s disease, and other health conditions. Magnesium level tests can help you stay proactive and make sure your body has what it needs to remain healthy.

What Does the Mg Blood Test Measure?

This test measures the body’s magnesium level.

Who Should Take a Magnesium Lab Test?

Testing may be recommended if you are experiencing symptoms linked to inadequate magnesium levels, such as:

• Appetite loss
• Nausea
• Fatigue
• Muscle weakness or spasms

A magnesium blood test is also helpful to monitor your levels if you have a medical condition or take medication that can raise the risk of deficiency.

Magnesium Level Test Preparation

There are no special instructions for taking a magnesium test.

Mg Blood Test Results

The normal range for magnesium lab test results is 1.7 to 2.2 mg/dL, although there may be slight variations depending on the lab. Your doctor may order some more tests, like the RBC magnesium test, or suggest lifestyle modifications, such as including more magnesium-rich foods in your diet if your levels aren’t where they should be. (Recommended daily magnesium intake is 310 to 320 mg for women and 400 to 420 mg for men.) Need more guidance? Schedule a telehealth appointment with one of our board-certified doctors.
