Magnesium is an essential mineral, which not only promotes the function of hundreds of enzymes, but also plays an essential role in the build-up of bones and teeth in addition to calcium. It also contributes greatly to the proper functioning of the nervous system and keeping blood pressure in a healthy range.
What is the goal of the test?
The purpose of the test is to determine the level of magnesium in blood.
In which cases is it recommended to have the test performed?
The test is recommended in case of weakness, nausea, diarrhoea or arrhythmia, as well as in case of abnormal calcium or potassium levels.
What sample is needed for the test?
A blood sample taken from a vein is necessary for the test.
What can the result indicate?
Low magnesium levels
Low levels of the mineral can occur if the patient’s magnesium intake is insufficient or not absorbed or excreted in excessive amounts.
Deficiency may also occur in case of prolonged diarrhoea, gastrointestinal diseases, hypoparathyroidism, uncontrolled diabetes, after surgery, or gestational toxaemia.
High magnesium levels
If the mineral is present in the body in higher-than-normal amounts, it may indicate a problem with kidney excretion or excessive magnesium supplementation.
Increased mineral levels may occur in case of hypothyroidism, hyperparathyroidism, renal failure, diabetic acidosis, dehydration, or taking magnesium-containing medications (laxatives, stomach acid reducers).
What to do after the test?
In all cases, please consult the specialist who ordered the test with the result, as the results of further tests may be required for an accurate diagnosis.
