Test ID: EFPO    
Electrolyte and Osmolality Panel, Feces

Specimen Type Describes the specimen type needed for testing

Fecal

Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.

Collection Container/Tube: Stool container (Supply T291)

Specimen Volume: 10 g

Collection Instructions: Collect a very liquid stool specimen.

Additional Information:

1. Do not send formed stool. In the event a formed stool is submitted, the test will not be performed. The report will indicate "A formed stool specimen was submitted for analysis. This test was not performed because it only has clinical value if performed on a watery stool specimen."

2. Osmolality results will be reported as mOsm/kg regardless of collection duration.

3. Sodium, chloride, and potassium will be reported as mmol/L

4. Magnesium and phosphorus will be reported as mg/dL

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
