Specimen Requirements:

Vaginal or Endocervical 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.
