WHO CBT MPN Kit Report
The World Health Organization (WHO) engaged KWR Laboratory to evaluate the Aquagenx® CBT EC+TC MPN 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.
Despite the difference in sensitivity between the two tests for very high concentrations of bacteria, our CBT EC+TC MPN Kit is an effective test that performs extremely well and compares favorably against Colilert Quanti-Tray 2000 in lower ranges of bacteria levels relevant to drinking water testing and quality. The CBT EC+TC MPN Kit also receives high marks for usability.
