LOINC display name : Magnesium (12H U) [Moles/Vol];
LOINC long common name : Magnesium [Moles/volume] in 12 hour Urine;
LOINC short name : Magnesium 12h Ur-sCnc;
LOINC description : Urinary magnesium excretion controls the magnesium balance. Urinary magnesium analyses
may be helpful in assessing the cause of abnormal serum magnesium levels. Increased
retention of magnesium can be seen in conditions that interfere with glomerular filtration.
Poor diet, malabsorption, and hypoparathyroidism are some possible causes of a low
urine magnesium. Urine magnesium testing pre and post therapeutic magnesium administration,
may be necessary to understand the significance of a low serum magnesium.;
