What does Magnesium - Serum measure?
This test measures the level of magnesium in the blood. Magnesium is an important mineral involved in muscle and nerve function, heart rhythm, bone health, and energy production. A healthcare professional may order this test to help assess suspected magnesium imbalance, monitor certain medical conditions or medicines, or investigate symptoms such as muscle cramps, weakness, irregular heartbeat, or seizures. Results are interpreted along with symptoms and other laboratory findings.
