Magnesium:
Magnesium concentrations in stool water above the normal levels of 0.7-1.2 mg/mL have been indicative of surreptitious abuse of magnesium containing laxatives.
NMS Labs calculated normal:
Approximately 0.5-10 mg/g (based on the reported range of magnesium eliminated per day in stool and the range of stool mass per day in adults).
Not for clinical diagnostic purposes.
Phosphorus:
Phosphorus concentrations in stool water averaged 1.8 +/- 0.3 mg/mL (ranged from 0.3-4.2 mg/mL) following administration of 105 mmol of sodium phosphate.
NMS Labs calculated normal:
Approximately 1.4-2.2 mg/g (based on the reported range of phosphorus eliminated per day in stool and the range of stool mass per day in adults).
Not for clinical diagnostic purposes.
