Magnesium (Mg)

Magnesium is an important mineral majorly found in bones and tissues of the human body. Magnesium supports the functioning of muscles, building proteins and strong bones and helps with the absorption of potassium and calcium. The deficiency of magnesium is linked to health issues such as deteriorating bone health, migraines, depression, cardiovascular disease and type 2 diabetes. Magnesium (Serum) blood test can detect the level of magnesium and help you identify if you need to increase your intake of foods rich in Magnesium.

Have you been feeling any of these symptoms lately?

The Magnesium (Serum) blood test is suitable for individuals experiencing one or more of the following symptoms: 

1. Nausea 

2. Weakness 

3. Muscle twitches and cramps

4. Neurological issues such as epilepsy, depression 

5. Weak Bones

6. Rapid Heartbeat

7. Abnormally High Blood Pressure

Additional Information

If you have low levels of magnesium, you may experience symptoms such as:




-Muscle cramps

-Problems with heart rhythm

Your doctor may order a magnesium blood test if they are concerned about your magnesium levels. The test can help determine if you need treatment for low magnesium levels.

Additional Insight from Dr Sameer Nakedar, MBBS, MRCGP, PGCert

Low magnesium levels may result from gut and kidney loss or certain medications. Symptoms can include muscle weakness, cramps, pins and needles, irregular heartbeats, raised blood pressure, weakness, seizures, drowsiness, or confusion. Fibre-rich foods contain magnesium, such as green leafy vegetables, bananas, wholemeal bread, brown rice, avocados, and some fish and meat. 

High magnesium levels may be caused by over-supplementation or by using too much of certain medications, such as antacids. Symptoms can include stomach upset, breathing problems and eye irritation, heart arrhythmias, weakness, nausea, and vomiting.

Why take the test?

The Magnesium (Serum) Blood Test screens for the deficiency of Magnesium in your blood. The blood test sample will detect the presence of Mg and identify if you need treatment for Hypomagnesemia. Along with the report, we also provide our Certified Doctors comments. Magnesium can be harmful either way, meaning excessive and reduced levels in the blood can cause health problems. Magnesium deficiency is often characterized by weakness, irritability, cardiac arrhythmia and vomiting. It has been linked to neurological issues such as depression and migraines. The human body regulates the level of magnesium in the body to prevent deficiency and eliminate excess of the element. However, individuals with type 2 diabetes and those with alcohol abuse disorder have a higher risk of reduced levels of Magnesium in their blood. If you or anyone you know is feeling any of these symptoms described above, they may be experiencing a lower level of Magnesium in their blood.

Expert’s Opinion

Experts Opinion on Magnesium Tests

"Magnesium is a common mineral found in every cell of the human body. It is essential for over 300 vital enzyme processes, which contribute to the body's muscle and nerve function, energy production, blood pressure control, and bone maintenance.

This test can help you check if your magnesium levels are normal, too high (also called hypermagnesemia) or too low (known as hypomagnesaemia)."
