Magnesium (Mg)
The test determines the blood magnesium level — an important trace element involved in nervous system, muscle, heart function, and metabolism. Magnesium is necessary for normal muscle contraction, nerve impulse transmission, maintaining heart rhythm, and energy metabolism.
Decreased magnesium is possible with: insufficient dietary intake, intestinal absorption disorder, chronic stress, alcoholism, diabetes mellitus, kidney diseases, prolonged diuretic use.
Elevated magnesium is possible with: renal failure, magnesium supplement overdose, dehydration.
Recommended for testing:
- people with cramps and muscle weakness
- patients with cardiovascular diseases
- with chronic stress and sleep disorders
- pregnant women (as prescribed by a doctor)
- people with GI diseases
- with long-term use of medications affecting electrolyte balance
