1 conjunctival swab in Aptima® transport tube or UTM

1 swab

Specimens must be collected using an Aptima Multi-Test collection kit (orange label), Aptima Unisex Swab specimen collection kit (white label), or UTM. To ensure collection of an adequate specimen, epithelial cells lining the conjunctiva should be obtained. To that effect, a cleaning swab should be used to remove and discard excess mucus prior to specimen collection. Submit one swab per collection tube.

Note: 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.

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.

C. trachomatis and N. gonorrhoeae are two of the most common causes of sexually transmitted infections, and both organisms can cause infectious conjunctivitis. Newborns are especially at risk for C. trachomatis or N. gonorrhoeae conjunctivitis if born to a mother with a genital infection.

Symptoms of C. trachomatis or N. gonorrhoeae conjunctivitis may include eye redness, eye lid swelling, and discharge. Symptoms in newborns infected at birth typically appear within two weeks.

A Not Detected (negative) result means that C. trachomatis or N. gonorrhoeae RNA was not present in the specimen above the limit of detection. A negative result does not rule out the possibility of infection and should not be used as the sole basis for patient management decisions.
