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.
