Magnesium

Magnesium is a mineral essential for muscle function, energy production, and nerve signaling. A 24-hour urine magnesium test measures how much magnesium your body excretes, helping assess magnesium status and kidney function. Low urinary magnesium may indicate deficiency or malabsorption, while high levels could suggest excessive losses or dietary overload. This test is useful for evaluating muscle weakness, irregular heartbeat, and metabolic concerns.
