Gonochek® for Neisseria spp

Gonochek®-II Neisseria Identification Test

Gonochek®-II is a rapid biochemical test for the confirmation and identification of clinically important Neisseria species. Using a single tube and a single test, Gonochek®-II enables laboratories to differentiate Neisseria gonorrhoeae, Neisseria meningitidis and Neisseria lactamica in just 30 minutes.

Designed for clinical microbiology laboratories, Gonochek®-II offers a simple, reliable and cost-effective solution for routine Neisseria identification, helping reduce laboratory workload while maintaining confidence in results.

Why Choose Gonochek®-II?

Unlike traditional carbohydrate utilisation methods, Gonochek®-II utilises chromogenic substrates to identify pathogenic Neisseria species through specific enzymatic reactions.
