| Collection: |
Random stool in clean, dry plastic container or in any of the following preservatives: 10% formalin, sodium acetate acetic acid formalin (SAF), or C & S medium. |
| Stability: |
Unpreserved specimen stable 48 hours refrigerated or 7 days frozen ≤ -20° C. Formalin and SAF specimens stable 2 months ambient or refrigerated. C & S medium stable 7 days refrigerated or frozen ≤ -20° C. |
| Standard Volume: |
5 gm solid stool or 5 mL liquid stool. |
| Minimum Volume: |
2 gm solid stool or 2 mL liquid stool. |
| Transport: |
Unpreserved specimen or C&S specimen refrigerated, or frozen on dry ice. Formalin or SAF specimen ambient or refrigerated. |
| Comments: |
As this test detects Giardia-specific antigen, it is more sensitive than the Ova and Parasite Exam (67000). However, this immunoassay is not a substitute for the Ova and Parasite Exam if parasites other than Giardia lamblia are suspected. |
| Rejection Criteria: |
Delayed transport, or specimen not transported at correct temperature. |
