A serum magnesium test measures the level of magnesium in the blood.
A blood test is the most common way to find out your magnesium level. You may hear the term “total serum magnesium test.” The magnesium blood test is like other blood tests you may have had. A nurse or other health worker will clean your skin, insert a needle into a vein in your arm or hand, and take a sample of blood.

You can test your magnesium levels by purchasing a simple at-home finger prick test kit which is then analysed at an accredited lab. Forth offers a number of blood tests which include magnesium such as our Nutri-check test and Menopause Health blood test.
Magnesium deficiency is frequently observed in conditions causing steatorrhoea or severe chronic diarrhoea such as Crohn's disease, ulcerative colitis, coeliac disease, Whipple's disease and short bowel syndrome.
Every organ in the body, especially the heart, muscles, and kidneys, needs the mineral magnesium. It also contributes to the makeup of teeth and bones.
Chronic magnesium deficiency is often associated with normal serum magnesium despite deficiency in cells and in bone; the response to oral supplementation is slow and may take up to 40 weeks to reach a steady state.
A magnesium blood test is used to check the level of magnesium in your blood. Levels that are too low are known as hypomagnesemia or magnesium deficiency. This is more common than levels that are too high, which is called hypermagnesemia.
Mg is essential in the metabolism of vitamin D, and taking large doses of vitamin D can induce severe depletion of Mg. Adequate magnesium supplementation should be considered as an important aspect of vitamin D therapy.
Doctors may order a magnesium test if a person has signs of low magnesium levels, such as weakness, muscle cramps or twitching, or an unusual heartbeat. The test also can be done if someone has a medical condition that makes abnormal magnesium levels more likely, such as a kidney problem.
Background. The normal plasma magnesium (Mg) concentration is maintained (primarily) by the kidney in the narrow range of 0.8 to 1.10 mmol/L.
Deficiencies due to poor absorption of magnesium from the gastrointestinal tract include: Diseases causing malabsorption such as celiac disease and inflammatory bowel disease. Gastric bypass surgery. Hereditary syndromes causing poor absorption of magnesium (primary intestinal hypomagnesemia).
It takes time to restore your magnesium levels fully. High-strength magnesium supplements can help to alleviate symptoms such as night-time leg cramps* and supply the body directly with enough magnesium.
One of the biggest factors is the presence of calcium in the diet, as high calcium foods can reduce your magnesium absorption (and vice versa). Foods containing sugar and caffeine may have similar effects.
As noted previously, magnesium deficiency reduces cardiac Na-K-ATPase, leading to higher levels of sodium and calcium and lower levels of magnesium and potassium in the heart. This increases vasoconstriction in the coronary arteries, which can induce coronary artery spasms, myocardial infarction and arrhythmias.
Hypomagnesemia associates with inflammation and risk of diabetes and hypertension, which may contribute to kidney function decline.
Diabetics or individuals with other blood sugar abnormalities, such as insulin resistance – because of increased urinary excretion, decreased dietary intake, and increased need. Individuals who consume a diet high in pastries and other junk foods – which are basically devoid of magnesium.
This overlap in the results suggests that stress could increase magnesium loss, causing a deficiency; and in turn, magnesium deficiency could enhance the body's susceptibility to stress, resulting in a magnesium and stress vicious circle.
If symptomatic and especially if the magnesium is <0.4 mmol/L recommend urgent admission. Magnesium may be given orally in a dose of up to 24 mmol Mg2+ daily in divided doses.
Fruit juices such as orange juice, cherry juice, and watermelon juice are all good sources of magnesium, potassium, and phosphorus. According to the FNDDS, the average school container (124 grams) of 100% orange juice provides : 13.6 mg of magnesium.
Bananas may be best known for being rich in heart-healthy and bone-strengthening potassium, but a medium-size banana also provides 32 mg of magnesium, in addition to 10.3 mg of vitamin C (a good source) and 3 g (a good source) of fiber, according to the USDA.
