Screening for the detection of Cryptosporidium and Giardia antigens present in stool
Negative (no detectable Cryptosporidium or Giardia antigen)
This test is approved for stool specimens only.
- Parasite Antigen, Giardia lamblia
- Parasite Antigen, Cryptosporidium
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 https://mlabs.umich.edu/media/175 for patient instructions.
Gastrointestinal panel (GIPAN) should be considered at additional cost, when multiple stool tests are desired . GIPAN is performed by real time PCR and identifies 21 stool pathogens.
Specimen received in PVA or other alcohol containing transport.
Patient In-house > 3 days
More than 1 specimen/day
Rectal swabs and diapers
Note: The Gastrointestinal panel (GIPAN) by PCR for Cryptosporidium and Giardia lamblia is more sensitive than the Cryptosporidium and Giardia Antigen enzyme immunoassay (CRGAG). Also, the Cryptosporidium and Giardia Antigen enzyme immunoassay (CRGAG) is more sensitive than Ova and Parasite Exam (OPE) for detection of Cryptosporidium and Giardia infection. If both CRGAG and GIPAN are ordered on the same sample, the CRGAG will be cancelled.
