Magnesium (24 hour urine test)

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Measurement of magnesium in 24-hour urine allows assessment of magnesium metabolism and renal excretion. Magnesium is an essential macroelement involved in nervous system function, muscle contraction, energy metabolism, and cardiac rhythm regulation.

The test is used to diagnose magnesium metabolism disorders, evaluate urinary magnesium loss, and identify causes of hypomagnesemia or hypermagnesuria.

Indications

• suspected magnesium deficiency or excess
• muscle cramps, weakness, fatigue
• cardiac rhythm disturbances
• chronic kidney disease
• endocrine and metabolic disorders
• monitoring magnesium therapy
• assessment of electrolyte balance

Procedure

The test requires urine collected over a 24-hour period in a dedicated container. After collection is completed, the total urine volume is measured, and a portion of the sample is sent to the laboratory for quantitative magnesium determination.

IMPORTANT!

It is crucial to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any discomfort or exacerbation of symptoms, it is essential to consult a healthcare professional for proper diagnostic testing and treatment recommendations. Only a qualified specialist can make an accurate diagnosis and determine the appropriate treatment plan. For the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
