Specimen Requirements:

Vaginal swab in 2.0 mL APTIMA® Vaginal Swab Collection Kit (orange label)

Collection Instructions:

Follow the instructions provided in the APTIMA® Vaginal Swab Collection Kit.

Remove the swab from the packaging and insert the swab into the vagina about two inches inside the opening. Gently rotate for 10 to 30 seconds, making sure that the swab touches the wall of the vagina so that moisture is absorbed by the swab. Withdraw the swab without touching the skin. Immediately place the swab into the transport tube so that the tip of the swab is visible below the tube label. Carefully break the swab shaft at the score line against the side of the tube and discard the top portion of the swab shaft. Tightly screw the cap onto the tube.

Methodology: Multiple
Clinical Significance: C. trachomatis infections are the leading cause of sexually transmitted diseases in the United States. C. trachomatis is known to cause cervicitis, pelvic inflammatory disease (PID), epididymitis and proctitis. It is also the most frequent cause of non-gonococcal urethritis in men. Among women, the consequences of Chlamydial infections are severe if left untreated. Approximately half of Chlamydial infections are asymptomatic.
Neisseria gonorrhoeae (gonococci) is the causative agent of gonorrhea. In men, this disease generally results in anterior urethritis accompanied by purulent exudate. In women, the disease is most often found in the cervix, but the vagina and uterus may also be infected.
