Screening for the detection of Giardia antigens present in stool.
Negative (no detectable Giardia lamblia antigen)
This test is approved for stool specimens only.
- Parasite Antigen, Giardia
- Parasite Exam, Giardia lamblia
- GIARDIA ANTIGEN
Collect fresh random stool specimen. Add stool specimen to transport vial until liquid reaches fill line. Emulsify specimen thoroughly in transport fluid. If necessary, place a urine bag on the patient to prevent urine contamination.
Acceptable specimens are stool sent in Stool Culture transport (orange cap) (Cary Blair) stored refrigerated up to 48 hours. If an unacceptable specimen is received, the client will be notified before disposal of the original specimen. See MLabs Stool Specimen Collection Instructions available online at http://mlabs.umich.edu/files/pdfs/GL-Stool_Collection_Guidelines.pdf for patient instructions.
Specimen received in PVA or other alcohol containing transport.
Patient In-house > 3 days
More than 1 specimen/day
Rectal swabs and diapers
Specimens sent for Giardia Antigen in Cary Blair transports may be stored at room temperature (18-30 C) or refrigerated (2-8 C) for up to four days, or frozen for up to one week.
Note: The Gastrointestinal panel (GIPAN) by PCR for Giardia lamblia is more sensitive than the Giardia Antigen enzyme immunoassay (GAG). Also, the Giardia Antigen enzyme immunoassay (GAG) is more sensitive than Ova and Parasite Exam (OPE) for detection of Giardia infection.
