WHO GEL Kit Report
The World Health Organization (WHO) engaged KWR Laboratory in The Netherlands to evaluate the Aquagenx® GEL EC CFU Kit. This initiative was partly driven by the UNICEF Rapid Water Quality Testing Project. Our test was evaluated against reference method IDEXX Colilert Quanti-Tray 2000, a lab-dependent test designed for testing wastewater and surface waters. Colilert Quanti-Tray 2000 has 96 wells that can quantify up to 2419 MPN of E. coli/100 mL.
Despite the difference in sensitivity between the two tests for very high concentrations of bacteria, our GEL EC CFU Kit performs extremely well and compares favorably against Colilert Quanti-Tray 2000 in lower ranges of bacteria levels relevant to drinking water testing and quality. Our GEL test provides precise colony counts of E. coli in 100 mL samples.
The GEL EC CFU Kit also receives high marks for usability.
