Reference Values
Reporting limit determined each analysis
Magnesium (mg/g)
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 (mg/g)
Phosphorus concentration 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 1.4-22 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.
