Preferred Specimen(s)

1 vaginal swab in Aptima® Transport Tube or
1 endocervical or urethral swab in Aptima® Transport Tube or
2 mL urine in Aptima® Transport Tube or
1 mL liquid cytology ThinPrep® PreservCyt® in Aptima® Transfer Tube or
0.5 mL SurePath™ Preservative Fluid in Aptima® Transfer Tube

Minimum Volume

1 vaginal swab in Aptima Transport • 1 endocervical or urethral swab in Aptima Transport Tube • 2 mL urine in Aptima Transport Tube • 1 mL ThinPrep PreservCyt in Aptima Transfer Tube • 0.5 mL SurePath fluid in Aptima Transfer Tube

Collection Instructions

Vaginal swab: Follow instructions in the Aptima Multitest Collection Kit (orange label).

Endocervical or urethral swab: Follow instructions in the Aptima Unisex Swab Specimen Collection Kit (white label). In females, to ensure collection of cells infected with N. gonorrhoeae/C. trachomatis, columnar epithelial cells lining the endocervix should be obtained. Excess mucus should be removed prior to sampling.

Urine: Direct patient to provide a first-catch urine (a maximum of 20-30 mL of the initial urine stream) into a urine collection cup free of any preservatives. 2 mL of urine specimen must be transferred into the Aptima Specimen Transport Tube within 24 hours of collection and before being assayed. Use the tube provided in the urine specimen collection kit. The fluid (urine plus transport media) level in the urine transport tube must fall within the clear pane of the tube label.

Labs performing cytology: Aliquot ThinPrep® PreservCyt® solution before performance of liquid-based cytology testing.

ThinPrep PreservCyt : Transfer 1 mL ThinPrep PreservCyt solution into Aptima Specimen Transfer Tube (green label) or Aptima Multitest Collection Tube (orange label) or Unisex Swab Specimen Collection Tube (white label).

SurePath: SurePath fluid must be transferred to Aptima® tube within 4 days of collection. Transfer 0.5 mL SurePath solution into Aptima® Specimen Transfer Tube (green label) or Aptima Multitest Collection Tube (orange label) or Unisex Swab Specimen Collection Kit (white label).

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.
