Gonochek - II
A diagnostic test kit for the confirmation of Neisseria organisms.
Gonochek®-II is the only test that uses a single tube and a single test to confirm and identify Neisseria spp. The test requires only a 2 minute set up and a 30 minute incubation time to confirm N. gonorrhoeae, N. meningitidis and N. lactamica.
Gonochek®-II is growth and pH independent. Hydrolysis of chromogenic substrates by enzymes within the test produces specific colour changes which confirm pathogenic Neisseria species.
