The 24-hour urine magnesium test measures the amount of magnesium excreted over a 24-hour period, which is crucial for evaluating magnesium metabolism and kidney function. We use automated spectrophotometry to ensure accurate and reliable results.
Collect all urine passed over a 24-hour period in a suitable container. At the end of the period, mix well and take a 10 mL aliquot for analysis. It is important to indicate the total volume of urine collected.
