How does the SNAP Giardia Test's sensitivity and specificity compare to other techniques?

Groat R. Survey of clinic practice and testing for diagnosis of Giardia infections in dogs and cats. Presented at: 2003 ACVIM Forum; June 4–8; Charlotte, NC. SNAP® Giardia Test and in-clinic microscopy test results are shown as percentages of samples that were identified as Giardia-positive by laboratory ELISA and DIFM methods.

The SNAP Giardia Test provides near-reference laboratory accuracy and is far superior to the poor performance of traditional in-clinic methods.

What type of Giardia does your test detect?

We identify Giardia lamblia, otherwise known as Giardia intestinalis or Giardia duodenalis, the primary species in mammals.

This refers to antigen that is not associated with a Giardia cyst wall or trophozoite. Our test detects a "free-floating" antigen that is dispersed in the fecal matter. This is why our sensitivity is much higher that microscopic techniques. (See Technology.)

How should a sample be saved?

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

Can this test be used for avian samples?

The SNAP Giardia Test is approved for canine and feline use only. Any use other than in canine and feline is off-label, and IDEXX has no data to support non-canine/feline application.

How should the SNAP Giardia Test Kit be stored?

SNAP devices and test reagents are stable until the expiration date when stored at 2°–7°C (36°–45°F). Please see the package insert for additional information. (642 KB)
