  2. Insert specimen collection swab (blue shaft swab in package with green printing) into endocervical canal.
  3. Gently rotate swab clockwise for 10 to 30 seconds in endocervical canal to ensure adequate sampling.
  4. Withdraw swab carefully; avoid any contact with vaginal mucosa.
  5. Remove the cap from swab specimen transport tube and immediately place specimen collection swab into specimen transport tube.
  6. Carefully break swab shaft at score line and discard the top portion of the swab shaft; use care to avoid splashing contents.
  7. Tightly re-cap the specimen transport tube tightly.

Female vaginal specimens

Option when a pelvic exam is not otherwise indicated for clinician or patient-collected specimen. Not for home use. Patient collection is limited to health care facilities where support/counseling is available to explain procedures and precautions.

Use Aptima Multitest swab collection kit

  1. Partially peel open the swab package and remove the swab. Do not touch the soft tip or lay the swab down. If the soft tip is touched, the swab is laid down, or the swab is dropped, use a new collection kit.
  2. Hold the swab, placing your thumb and forefinger in the middle of the swab shaft covering the score line. Do not hold the swab shaft below the score line.
  3. Carefully insert the swab into the vagina about 2 inches past the introitus and gently rotate the swab for 10 to 30 seconds. Make sure the swab touches the walls of the vagina so that moisture is absorbed by the swab and then withdraw the swab without touching the skin.
  4. While holding the swab in the same hand, unscrew the cap from the tube, taking care not to spill the contents of the tube. If the contents of the tube are spilled, use a new collection kit.
  5. Immediately place the swab into the transport tube so that the score line is at the top of the tube.
  6. Carefully break the swab shaft at the score line against the side of the tube.
  7. Immediately discard the top portion of the swab shaft.
  8. Tightly screw the cap onto the tube.

Male urethral swab specimens:

  1. Insert specimen collection swab (blue shaft swab in package with green printing) 2 to 4 cm into urethra.

Urine sample collection

  

Male and female urine specimens:

  1. Direct patient to provide first-catch urine (approximately 20 to 30 ml of initial urine stream) into urine collection cup free of any preservatives.
    • The cup should be removed from the urine stream when 20-30 ml of urine is in the cup. Collection of larger volumes of urine may result in specimen dilution that may reduce test sensitivity and should not be sent for testing.
  

Urine specimens must be transferred to an Aptima specimen transport tube by the collecting site, within 24 hours of collection, and prior to specimen transport.

  1. Remove cap from urine specimen transport tube and transfer 2ml of urine into urine specimen transport tube using disposable pipette provided. The correct volume of urine has been added when fluid level is between black fill lines on urine specimen transport tube label.
  2. If refrigerated, urine may be transferred to the transport tube at the collection site within 24 hours.
  3. Tightly screw the cap onto the tube.
  • Place each Aptima swab or urine transport tube in an individual small zip lock bag supplied with the kit.
