Magnesium (Urine)
The Magnesium (Urine) test measures the amount of magnesium excreted in the urine over a 24-hour period. This test helps assess how the kidneys handle magnesium and can provide insight into magnesium balance.
Urinary magnesium testing is useful when investigating unexplained magnesium deficiency, kidney disorders, or electrolyte imbalances.
High urinary magnesium levels may indicate excessive losses through the kidneys, while low levels may suggest inadequate intake or gastrointestinal absorption issues.
This test is often interpreted alongside blood magnesium tests to provide a more complete picture of magnesium metabolism.
