Use

This assay is intended for the qualitative detection of Chlamydia trachomatis and Neisseria gonorrhoeae in ocular (conjunctival) specimens from patients suspected of having infectious conjunctivitis caused by C. trachomatis or N. gonorrhoeae. It does not detect Chlamydophila (Chlamydia) pneumoniae or other Chlamydia species. Newborns are especially at risk for C. trachomatis or N. gonorrhoeae conjunctivitis if born to a mother with a genital infection.

Special Instructions

Results from the Aptima Combo 2 Assay should be interpreted in conjunction with other laboratory and clinical data available to the clinician. The Aptima Combo 2 Assay is not intended for the evaluation of suspected sexual abuse or for other medico-legal indications.

Limitations

For a complete list of assay limitations review the manufacturer’s package insert. Repeat testing of the same positive sample using the same methodology is not recommended for most populations and does not improve positive predictive value. In rare circumstances confirmatory testing may be considered using alternate-target tests.
