Phosphorus, Stool (Sendout)

Interpretation

Method

Inductively Coupled Plasma/Optical Emission Spectrometry (ICP/OES)

Reference Range

Ref. Range Notes

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 - 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)

Interferences and Limitations

Specimens for elemental testing should be collected in certified metal-free containers. Elevated results for elemental testing may be caused by environmental contamination at the time of specimen collection and should be interpreted accordingly. It is recommended that unexpected elevated results be verified by testing another specimen in a trace metal free container.
