Includes
Chlamydia trachomatis, Neisseria gonorrhoeae, and Trichomonas vaginalis
Preferred Specimen
1 vaginal swab in Aptima® Transport Tube or
1 endocervical swab in Aptima® Transport Tube or
2 mL female urine in Aptima Transport Tube
1 endocervical swab in Aptima® Transport Tube or
2 mL female urine in Aptima Transport Tube
Minimum Volume
1 vaginal swab • 1 endocervical swab • 2 mL urine
Other Acceptable Specimens
Female or male Urine (no preservatives): 2 mL of urine, specimen must be transferred into the Aptima® Urine Transport Medium within 24 hours of collection and before being assayed.
Instructions
Vaginal swab: Follow instructions in the Aptima® Multitest Collection Kit (orange label).
Endocervical 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.
Endocervical 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.
