Negative
Interpretation
A positive result indicates the presence of nucleic acid from Neisseria gonorrhoeae and strongly supports the diagnosis of gonorrheal infection.
A negative result indicates the absence of N gonorrhoeae nucleic acid. A negative result does not exclude the possibility of infection. If clinical indications strongly suggest gonococcal or chlamydial infection, additional specimens should be collected for testing.
A result of inconclusive indicates that a new specimen should be collected.
The predictive value of an assay depends on the prevalence of the disease in any specific population. In settings with a high prevalence of sexually transmitted infections, positive assay results have a high likelihood of being true-positive results. In settings with a low prevalence of sexually transmitted infections, or in any settings in which a patient's clinical signs and symptoms or risk factors are inconsistent with gonococcal urogenital infection, positive results should be carefully assessed, and the patient retested by other methods (eg, culture for N gonorrhoeae) if appropriate.
