Magnesium - 24 hours Urine

This test is usually ordered when a healthcare provider suspects that you may have an imbalance of magnesium in your body. Symptoms of a magnesium imbalance can include muscle weakness, cramps, irregular heart rhythms, or changes in mental status such as confusion or seizures.

The test requires you to collect all urine passed in a 24-hour period. This collection is started after you empty your bladder in the morning and continues for the next 24 hours. The collected urine is then sent to a laboratory for analysis.

Increased levels of magnesium in the urine can suggest excessive intake of magnesium, either through diet or supplements, or that your kidneys are not reabsorbing magnesium properly. Decreased levels can suggest inadequate intake or absorption of magnesium, or that your body is losing too much magnesium through the gastrointestinal tract.

The use of certain medications and supplements, kidney function, and the amount of magnesium in your diet can all influence the test results.

Your healthcare provider will give you a special container to collect the urine, and specific instructions on how to collect and store the samples. It is crucial to collect all urine passed during the 24 hours for accurate results.

Treatment will depend on whether your magnesium levels are too high or too low, and on the underlying cause. Treatment options can include changes in diet, supplements, medications, or treating any underlying medical condition that is causing the imbalance.
