What is a Magnesium Test used for?
Your doctor may recommend this test if you show symptoms of magnesium overdose/poisoning (hypermagnesemia), which are:
- Slow heart rate
- Low blood pressure
- Extreme fatigue, muscle fatigue
- Body ache
- Difficulty in breathing
If not treated timely, it can lead to abnormal heart rhythm, resulting in cardiac arrest or death. Additionally, your healthcare provider may order this test periodically if you have a kidney disorder (kidney failure), hypothyroidism, disease of adrenal glands, depression or if you are on certain antipsychotic medications like lithium therapy. It helps to monitor if you are retaining or excreting excessive quantities of magnesium.
Another purpose of this test is to check if you suffer from hypomagnesemia or magnesium deficiency.
In this, you may experience symptoms such as
- Loss of appetite
- Personality changes
If the deficiency continues, you may suffer from seizures, irregular heart rhythms, muscle cramps, and numbness. Other problems for which doctors use this test are:
- Chronic low calcium and potassium levels
- Malnutrition or malabsorption problems
Kidney problems, diabetes, or chronic diarrhoea
What is included in a Magnesium Test?
Magnesium has a close association with the calcium content in your body. Also, other elements like phosphate and potassium may influence the test results. Hence, your doctor may also advise calcium and electrolyte tests, along with the magnesium test.
Procedure for a Magnesium Test
A magnesium test takes only a few minutes, and the procedure involves the following steps:
- In the first step, the site from where the blood sample is collected is cleaned using an antiseptic solution
- Then, a plastic band is tied and tightened so that the veins are visible clearly
- After locating the vein, the lab technician inserts the needle and withdraws the blood. You may feel a quick sting.
- This blood sample is stored in a test tube and sent to the laboratory for further evaluation
- Laboratory experts use advanced examination techniques to analyze the blood sample and prepare the report
How to prepare for a Magnesium Test?
Before a magnesium test:
- You may not require fasting for magnesium tests unless your doctor has also scheduled other tests that need fasting.
- Inform your doctor about all the medications and supplements that you take regularly. Your doctor may recommend stopping the intake of these medications.
- Also, let your doctor know if you are pregnant.
- Make sure that you wear loose and comfortable clothing with sleeves, which you can roll up quickly, or preferably wear a half sleeve.
- If you are tense about the test, try listening to your favourite music, or you can do some breathing exercises.
Things to consider after a Magnesium Test is complete
After the test is completed, the technician removes the needle and the elastic band. The site is then covered with a bandage or cotton to stop the bleeding. You may feel the pain that usually subsides in a few days. There are no restrictions after the test. You can resume your routine activities.
After your reports are ready, you must meet the doctor to discuss the results. If your results show you have a magnesium deficiency, your doctor may prescribe you magnesium supplements to increase the level.
In case of elevated magnesium levels, you will be treated at the hospital with appropriate medications depending on the severity of cardiac or respiratory effects.

- The urine magnesium test
- RBC magnesium test
- Ionized magnesium test
How to read the Magnesium Test report?
The magnesium normal range is: 0.85 to 1.10 mmol/L (1.7 to 2.2 mg/dL approx.). The age-wise range is as follows:
- Below 0.85 mmol/L (Less than 1.7 mg/dL approx.) is considered hypomagnesemia (deficiency of magnesium)
- Hypermagnesemia (magnesium deficiency) is when your magnesium level is above 1.10 mmol/L (Above 2.2 mg/dL approx.)
Sometimes the reference values may vary depending on your body type, overall health condition, age, gender, and the laboratory where the test is performed.
Remember that your doctor is the best person who can explain the results accurately. So, a visit to the doctor is highly advisable once you receive your test reports.
