The normal range for magnesium in the blood is 1.7 to 2.3 mg/dL. Normal values might slightly differ among the varied laboratories. That’s because some laboratories use varied test samples and measurements. You need to consult your doctor about the meaning of the test report.
Magnesium blood test results can vary based on health history, gender, age, the method used for testing, and other things. However, the test results do not always mean that you have a certain problem.
The results of a magnesium blood test are provided in mEq/L or milliequivalents per litre. Normal test results are basically in a range of:
- 1.4 to 1.7 mEq/L for children
- 1.6 to 2.6 mEq/L for adults
- 1.4 to 2 mEq/L for new-borns
Abnormal levels of magnesium in the blood can have different possible causes. Increased levels can be associated with kidney diseases because the kidneys excrete magnesium. Low magnesium levels can be a sign of digestive issues, long-term alcoholism, and malnourishment.
