Abstract: We compared the performance of cobas 4800 PCR for Neisseria gonorrhoeae with culture and found an association between pipetting errors and positive culture, caused by mucopurulent discharge. The problem may be resolved by pretreating samples with Sputasol, thus improving detection of both Chlamydia trachomatis and Neisseria gonorrhoeae.
