IDEXX Water Testing

IDEXX is a global leader in water microbiology testing, providing innovative, easy-to-use solutions for detecting microbial contamination in water. The company is best known for its presence/absence (P/A) and quantification tests for coliforms, E. coli, Enterococci, and Legionella, widely used in drinking water, wastewater, recreational water, and industrial systems. IDEXX products are trusted by water utilities, environmental labs, and health agencies worldwide due to their accuracy, reliability, and compliance with international standards.

One of IDEXX’s most recognized products is Colilert, which simultaneously detects total coliforms and E. coli in water within 24 hours. This test uses Defined Substrate Technology (DST), where enzymes produced by target bacteria cause a distinct color or fluorescence change, allowing for simple visual interpretation or automated reading. Colilert is U.S. EPA-approved and widely accepted in regulatory frameworks across the globe.

Other popular IDEXX tests include Enterolert for detecting Enterococci in marine and freshwater samples, and Legiolert, a highly sensitive method for identifying Legionella pneumophila in building water systems. All tests are designed for minimal hands-on time, room temperature incubation, and straightforward results, reducing labour and increasing throughput in the lab.

IDEXX also offers a range of equipment and accessories, such as Quanti-Tray® systems, sealers, and incubators, all tailored to streamline the testing process. Their digital platforms help labs manage and document results efficiently, ensuring traceability and compliance.

In summary, IDEXX has revolutionized water testing with its rapid, accurate, and user-friendly methods for microbial detection. Its solutions help protect public health by ensuring early detection of waterborne pathogens, meeting regulatory requirements, and supporting safe water management across various sectors.
