# Magnesium

> This test measures the level of magnesium in your blood, a mineral essential for proper muscle, nerve, and heart function. It helps determine if abnormal levels are contributing to symptoms like muscle weakness, tremors, or irregular heartbeats. Doctors often use these results to evaluate kidney health and to check for nutritional imbalances or problems absorbing minerals. However, this test alone cannot diagnose the specific medical condition causing the mineral imbalance.
