Swab and Go

A simple point-of-care swab of the infected area. No messy solutions to measure or storage requirements. Results available while your patient waits.

A must have diagnostic in every veterinary practice!

Peace of mind
Antibiotic Stewardship


The OTTER will give the opportunity to test for bacterial infections directly using a point-of-care device approximately the size of your standard television remote control. The device pairs with a disposable cartridge based sensor, on which you simply swab your sample of interest. Results are available in under 2 minutes and can even be tracked over time to follow infection treatment. This process is really fast. While we say the result is ready in under 2 minutes, the actual scan only takes seconds.

The OTTER has been built from the ground up to focus on ease of use, speed and accuracy. New users will love the space saving form factor and the convenience of cartridges. All of our products are covered by an industry leading warranty and a “here to help” service mentality.
