How is magnesium deficiency diagnosed?
If a doctor suspects abnormal magnesium levels, they may recommend the patient undergoes a magnesium test.
The NHS website explains: “Abnormal magnesium levels can occur in conditions that affect the functioning of your kidneys or intestines.
“A magnesium test may be recommended as part of a series of tests if you have symptoms such as nausea, weakness or cardiac arrhythmia (irregular heartbeat).
“You may have abnormal levels of magnesium, calcium or potassium in your blood.”
