Magnesium Test measures the level of Magnesium in the blood.
Magnesium is an essential mineral in the body, it helps muscles function properly and is important in blood sugar regulation, it is needed for your nervous, gastrointestinal and cardiovascular systems to work properly.
Magnesium deficiency (hypomagnesemia) may be linked to malnutrition causing poor absorption by the kidneys. Magnesium excess (Hypermagnesemia) may be caused by antacids (which contain magnesium) causing a decreased ability of the kidneys to excrete it.
Preparation: If possible, have your test early in the morning or shortly after waking.
