SNAP® Giardia Test specifications

 

SNAP Giardia   The SNAP Giardia Test Kit is a rapid enzyme immunoassay for detection of Giardia antigen in canine and feline feces. The presence of this antigen in fecal samples indicates the animal has ingested Giardia cysts, may be actively infected, and may be shedding cysts in feces. Symptoms include diarrhea, vomiting and anorexia, and infections are particularly dangerous for immunocompromised animals.

Storage   SNAP devices and test reagents are stable until the expiration date when stored at 2°–7°C (36°–45°F).

All components must be at room temperature before running the test. This may take up to 30 minutes, depending upon the temperature in your laboratory. DO NOT HEAT.

Sample Information   Canine or feline feces can be used fresh, previously frozen, or stored at 2–7°C (36–45°F) for up to seven days.

Samples must be at room temperature before beginning the test procedure.
