Test Catalog

Test ID: GIAR    
Giardia Antigen, Feces

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

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

Fecal

Advisory Information

Duodenal and small bowel aspirates are not acceptable for this test. If sprue is suspected, order test OAP / Parasitic Examination.

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.

Submit only 1 of the following specimens:

 

Preferred Specimen Type: Preserved stool

Supplies: Formalin - Meridian 10% Buffered Neutral (T466) or Stool Collection Kit, Random (T635)

Container/Tube:

Preferred: Stool container with 10% buffered formalin preservative (T466)

Acceptable: SAF (sodium acetate formalin)

Specimen Volume: 5 g

Specimen Stability Information: Ambient (preferred)/Refrigerated

 

Acceptable Specimen Type: Unpreserved stool

Supplies: Stool container, Small (Random), 4 oz (T288) or Stool Collection Kit, Random (T635)

Container/Tube: Stool container (T288)

Specimen Volume: 5 g

Specimen Stability Information: Frozen

Forms

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.

2 g

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

Hemolysis

NA

Lipemia

NA

Icterus

NA

Other

Grossly bloody stool (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.
