Science
How the Enterolert-E Test works
The Enterolert-E Test uses IDEXX's proprietary Defined Substrate Technology (DST) nutrient indicator to detect enterococci. This nutrient indicator fluoresces when metabolised by enterococci. DST improves accuracy and avoids the need for hazardous sodium azide suppressants used in traditional media.
