IDEXX SNAP tests outperform Abaxis tests, peer-reviewed studies confirm

Performance and accuracy are paramount when testing for infectious diseases


Anaplasma*

Sensitivity

IDEXX SNAP
4Dx Plus Test

84.2%

Abaxis VetScan® Canine
Anaplasma Rapid Test

45.2%

More than 1 in 2 Anaplasma-positive results could be false negatives.1

Ehrlichia

Sensitivity

IDEXX SNAP
4Dx Plus Test

90.8%

Abaxis VetScan® Canine
Ehrlichia Rapid Test

69.2%

More than 1 in 4 Ehrlichia-positive results could be false negatives.2

Giardia

Sensitivity

IDEXX SNAP
Giardia Test

87.1%

Abaxis VetScan® Canine
Giardia Rapid Test

70%

More than 1 in 4 Giardia-positive results could be false negatives.3

In “high stakes” testing, accuracy could be life or death


With the current FeLV prevalence of 3%, you’d get three true positives if you tested 100 cats.

The Abaxis VetScan® Feline FeLV/FIV Rapid Test was only 85.7% specific in a third party, peer-reviewed study by Julie K. Levy, DVM, PhD, DACVIM4…thus a “positive” VetScan Rapid test result was much more likely wrong than right. The IDEXX SNAP FIV/FeLV Combo Test showed 100% specificity.

 

For 25 years, you’ve trusted IDEXX to deliver the most accurate point of care tests in veterinary medicine.
