# Magnesium, Urine

> This test measures the amount of magnesium being removed from your body through your urine. It helps show whether your kidneys are holding onto enough magnesium or if you are losing too much due to medications or other factors. This comparison helps doctors determine if low magnesium levels are caused by kidney issues rather than poor dietary intake. However, this test alone cannot diagnose a specific disease or determine the exact amount of magnesium stored in your body.
