Test Catalog

Test ID: CYCL    
Cyclospora Stain

Testing Algorithm Delineates situation(s) when tests are added to the initial order. This includes reflex and additional tests.

For other diagnostic tests that may be of value in evaluating patients with diarrhea; the following algorithms are available in Special Instructions:

-Parasitic Investigation of Stool Specimens Algorithm

-Laboratory Testing for Infectious Causes of Diarrhea

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, complete, print, and send a Microbiology Test Request Form (T244) with the specimen (


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

The presence of barium will interfere with this test.


Submit only 1 of the following specimens:



Specimen Type: Preserved stool


Preferred: ECOFIX preservative (Supply T219)

Acceptable: Container with 10% formalin

Specimen Volume: 10 g

Specimen Stability Information: Ambient (preferred)/Refrigerated


Specimen Type: Unpreserved stool

Container/Tube: Stool container (Supply T288)

Specimen Volume: 5 g

Specimen Stability Information: Refrigerated 3 days (preferred)/Frozen



Specimen Type: Duodenal aspirate

Container/Tube: Sterile container or placed in Ecofix preservative (Supply T219)

Specimen Volume: Entire collection

Specimen Stability Information: Refrigerated <72 hours in sterile container/Ambient in Ecofix preservative

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.

Preserved stool: 1 g/Unpreserved stool: 2 g

Reject Due To Identifies specimen types and conditions that may cause the specimen to be rejected









Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
