Specimen Type Describes the specimen type needed for testing


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.

Forms: If not ordering electronically, submit a Microbiology Request Form (Supply T244) with the specimen.


Patient should avoid use of anti-diarrheal medication (ie, loperamide or Pepto-Bismol).


The presence of barium will interfere with this test.

Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space.

In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
