Chlamydia trachomatis and Neisseria gonorrhoeae by Nucleic Acid Amplification (GEN-PROBE)
Specimen Type 
Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Specimen source is required.
Submit only 1 of the following specimens:
Swab specimen must be collected using an APTIMA Collection Unisex Swab (Supply T583) or APTIMA Collection Vaginal Swab (Supply T584). These swabs are contained in the APTIMA Collection Kit.
Specimen Type: Endocervix
Container/Tube: APTIMA Collection Unisex Swab (Supply T583)
Specimen Volume: Swab
Collection Instructions:
1. Use cleaning swab (white shaft) to remove excess mucus from endocervix and discard.
2. Insert second swab (blue shaft) 1 to 1.5 cm into endocervical canal, and rotate swab gently for 30 seconds. Avoid touching vaginal wall when removing swab.
3. Place second swab into transport tube provided in collection kit. Snap off swab at score line so swab fits into closed tube.
4. Cap tube securely, and label tube with patient's entire name, and date and time of collection.
5. Transport and store swab container at 2 to 30 degrees C (refrigerate is preferred temperature) within 60 days of collection. If longer storage is needed, freeze at -20 to -70 degrees C for 12 months.
Specimen Type: Vaginal
Container/Tube: APTIMA Collection Vaginal Swab (Supply T584)
Specimen Volume: Swab
Collection Instructions:
1. Insert swab (pink shaft) about 5 cm past introitus and rotate gently for 30 seconds.
2. Place swab into transport tube provided in collection kit. Snap off swab at score line so swab fits into closed tube.
3. Cap tube securely, and label tube with patient's entire name, and date and time of collection.
4. Transport and store swab container at 2 to 30 degrees C (refrigerate is preferred temperature) within 60 days of collection. If longer storage is needed, freeze at -20 to -70 degrees C for 12 months.
Specimen Type: Urethra (Males Only)
Container/Tube: APTIMA Collection Unisex Swab (Supply T583)
Specimen Volume: Swab
Collection Instructions:
1. Patient should not have urinated for at least 1 hour prior to collection.
2. With a rotating movement, insert swab (blue shaft) 2 to 4 cm into urethra.
3. Once inserted, rotate swab gently at least 1 full rotation using sufficient pressure to ensure swab comes into contact with all urethral surfaces. Allow swab to remain inserted for 2 to 3 seconds.
4. Place swab in transport tube provided in collection kit. Snap off swab at score line so swab fits into closed tube.
5. Cap tube securely, and label tube with patient's entire name, and date and time of collection.
6. Transport and store swab container at 2 to 30 degrees C (refrigerate is preferred temperature) within 60 days of collection. If longer storage is needed, freeze at -20 to -70 degrees C for 12 months.
Specimen Type: Urine (Males and Females)
Container/Tube: APTIMA Urine Specimen Transport Tube (Supply T582)
Specimen Volume: 15-20 mL
Collection Instructions:
1. Patient should not have urinated for at least 1 hour prior to specimen collection.
2. Patient should collect first portion of random voided urine (first part of stream) into a sterile, plastic, preservative-free container.
3. Transfer 2 mL of urine into the urine specimen transport tube using the disposable pipette provided within 24 hours of collection. The correct volume of urine has been added when the fluid level is between the black fill lines on the urine transport tube.
4. Transport and store swab container at 2 to 30 degrees C (refrigerate is preferred temperature) within 60 days of collection. If longer storage is needed, freeze at -20 to -70 degrees C for 12 months.
Specimen Type: ThinPrep Specimen (Endocervix)
Container/Tube: ThinPrep (also called PreservCyt) Collection Kit
Specimen Volume: 1 mL
Collection Instructions:
1. Aliquot ThinPrep specimen for Chlamydia and/or Neisseria testing before processing for Pap smear. For each specimen, use a new pair of clean gloves.
2. Vortex ThinPrep/PreservCyt vial 3 to 10 seconds. Within 1 minute of vortexing:
a. Transfer 1 mL of specimen into the APTIMA Specimen Transfer Tube (Supply T652) using a disposable transfer pipette or a pipette tip containing a filter (aerosol barrier or hydrophobic plug).
b. Process only 1 ThinPrep and transfer tube set at a time.
c. Recap APTIMA Specimen Transfer Tube tightly and gently invert 3 times to mix.
3. Label APTIMA transfer tube with appropriate label.
4. Use remainder of ThinPrep specimen for Pap testing.
5. Transport and store swab container at 2 to 30 degrees C (refrigerate is preferred temperature) within 60 days of collection. If longer storage is needed, freeze at -20 to -70 degrees C for 12 months.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.
