Detection of Neisseria gonorrhoeae relies increasingly on nucleic acid amplification tests ( NAAT s). The specificity of many gonococcal NAAT s has been suboptimal and supplementary testing remains recommended in Europe and several additional countries. The novel dual‐target GeneProof Neisseria gonorrhoeae PCR kit, targeting porA pseudogene and 16S rRNA gene, showed a high specificity and sensitivity when isolates of non‐gonococcal Neisseria and related species (n = 144), and gonococci (n = 104) were tested. However, rare gonococcal porA mutants were only detected in the 16S rRNA gene target and two non‐gonococcal isolates showed a low‐level cross‐reactivity in the 16S rRNA gene target. The detection limit for both targets was 1.5 copies per reaction.
