Medium riskHealth Canada

An official Health Canada notice concerns Xpert® ct ng. Cepheid has become aware of a rare genetic mutation event between Neisseria gonorrhoeae and Neisseria meningitidis that caused some Neisseria gonorrhoeae strains to lack target sites for the Cepheid Xpert® CT/NG test, leading to false negative results. Cepheid recommends that laboratories and clinics using the Xpert® CT/NG test as their molecular method for the detection of N. Gonorrhoeae monitor for decreases in the positivity rate and ensure that discordant laboratory results (e.g. Testing negative on the Xpert® CT/NG test but positive for NG by culture/microscopy or testing negative on Xpert® CT/NG test but positive for NG using another NAAT) be investigated further and reported to cepheid. Published 2025-10-24.
