Gono Gen coagglutination test for confirmation of Neisseria gonorrhoeae

Abstract

The Gono Gen (Micro-Media Systems, Inc., Potomac, Md.) coagglutination test was compared with the sugar utilization test and with a direct fluorescent antibody test for confirmation of Neisseria gonorrhoeae. Of 110 gonococcal clinical isolates, 109 were positive by the Gono Gen test. Of 57 nongonococcal gram-negative diplococci, all were negative by the Gono Gen test. We conclude that the Gono Gen test is sensitive and highly specific and provides a rapid method for the confirmation of N. gonorrhoeae.
