Normal magnesium levels in humans fall between 1.5 - 2.5 mg/dL. Usually a serum level less than 0.7 mmol/L is used as reference for hypomagnesemia. Between 1.5 - 2.5 mg/dL.
Testing magnesium levels to find if they are normal requires a simple blood draw. Levels are considered normal in the range of 1.7 to 2.2 mg/dL. Your doctor might choose to test your magnesium levels if you have tested low for potassium and calcium or if you have a history of kidney disease. Sometimes your body will released store magnesium from your bones to make up for a deficiency. A magnesium test is used to measure the level of magnesium in the blood (or sometimes urine). Abnormal levels of magnesium are most frequently seen in conditions or diseases that cause impaired or excessive excretion of magnesium by the kidneys or that cause impaired absorption in the intestines. When magnesium and/or calcium supplementation is necessary, the level of magnesium in the blood may be checked at intervals to monitor the effectiveness of treatment. Normal Serum Magnesium Test Results. Serum magnesium is measured in milligrams per deciliter (mg/dL). A normal range is 1.7 to 2.3 milligrams per deciliter. The exact standards for normal results may vary depending on your age, health, body type, and sex, as well as the lab performing the test. You may also take them if you have low potassium and calcium levels in your blood. If your doctor suspects that your magnesium level is too low or too high, he or she may order a serum magnesium test. All this test involves on your part is a basic blood draw. For this reason, blood levels of magnesium are not an adequate means of establishing the total amount of available magnesium. In terms of serum magnesium, the majority is bound to chelators, including ATP, ADP, proteins and citrate. Roughly 33% is bound to proteins, and 5–10% is not bound. This free magnesium is essential in regulating intracellular magnesium. Normal plasma Mg is 1.7–2.3 mg/dl (0.69–0.94 mmol/l). The kidneys regulate the serum magnesium. About 2400 mg of magnesium passes through the kidneys daily, of which 5% (120 mg) is excreted through urine. For an adult, 1.3-2.1 milliequivalents of magnesium per liter of blood is the normal magnesium amount. However, magnesium levels can normally be low for women in the second and third trimesters of their pregnancy.  Hypomagnesemia is an electrolyte imbalance and is indicated by a low level of magnesium in the blood. The normal adult value for magnesium is 1.5-2.5 mEq/L. Magnesium is one of many electrolytes in your body and normal levels of magnesium are important for the maintenance of heart and nervous system function. Normal magnesium levels in humans fall between 1.5 - 2.5 mg/dL. Usually a serum level less than 0.7 mmol/L is used as reference for hypomagnesemia (not hypomagnesia which refers to low magnesium content in food/supplement sources). This free magnesium is essential in regulating intracellular magnesium. Normal plasma Mg is 1.7–2.3 mg/dl (0.69–0.94 mmol/l). The kidneys regulate the serum magnesium. About 2400 mg of magnesium passes through the kidneys daily, of which 5% (120 mg) is excreted through urine. The normal range of Magnesium Blood Tests on Laboratory evaluations is from approximately 1.5 to 2.5 mEq/liter-although this will vary slightly depending upon each individual laboratory-but having a 'normal' level simply is worthless information if you are having problems. You don't need a test, and testing is really not very good because magnesium needs and levels change minute by minute and hour by hour. A normal level of magnesium in the doctor's office could be significantly lower after a stressful drive home in terrible traffic or an emotional phone call with your mother. Magnesium (Mg). Guide. A magnesium test checks the level of magnesium in the blood. Magnesium is an important electrolyte needed for proper muscle, nerve, and enzyme function. It also helps the body use energy and is needed to move other electrolytes (potassium and sodium) into and out of cells. Most of the magnesium in the body is found in the bones and inside the cells. Only a tiny amount of magnesium is normally present in the blood. Tests for other electrolytes, such as calcium, potassium, sodium, and phosphorus, may be done along with a test for magnesium. Guide.
