Test Catalog

Test Name

Test ID: ROTA    
Rotavirus Antigen, Feces

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

See Parasitic Investigation of Stool Specimens Algorithm in Special Instructions for other tests that may be useful in the evaluation of a patient with 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.

Supplies: Stool Collection Kit, Random (T635)


Preferred: Sterile stool container

Acceptable: Swab

Specimen Volume: 5-10 g

Additional Information: Place specimen in a tightly-sealing plastic bag.


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.

1 g

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








Grossly bloody (containing no visible stool) or very mucoid stool

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