Collection Information
Specimen Required
1 Vaginal, endocervical or urethral swab collected in an APTIMA Vaginal Swab Specimen Collection kit or Multi-Test Collection kit, or Unisex Swab Specimen Collection Kit, 2 mL Urine with no preservative transferred into an APTIMA Urine Collection kit or 1 mL PreservCyt (ThinPrep) transferred into an APTIMA Specimen Transfer Tube (green label) or APTIMA Vaginal Swab Specimen Collection kit or Multi-Test Collection kit Collection Tube (orange label)
Container Type
APTIMA Unisex Swab or Urine Transport Tube
Collection Instructions
Swabs: Swab MUST be submitted in APTIMA Vaginal Swab Specimen Collection kit or Multi-Test Collection kit, or Unisex Swab Specimen Collection tube. Follow instructions in the APTIMA Swab Specimen Collection Kits for Vaginal, Endocervical and Urethral Swab Specimens package insert. In females, to ensure collection of an adequate specimen, columnar epithelial cells lining the endocervix should be obtained. To that effect, excess mucus should be removed prior to sampling by using the white shaft cleaning swab which is discarded after use. Collection Container: APTIMA Vaginal Swab Specimen Collection kit or Multi-Test Collection kit, or Unisex Swab Specimen Collection Kit. Urine: Urine MUST be submitted in APTIMA Urine Specimen Collection tube within 24 hours of collection. The patient should not have urinated for at least one hour prior to specimen collection. Direct patient to provide a first-catch urine (approximately 20-30 mL of the initial urine stream) into a urine collection cup free of any preservatives. Collection of larger volumes of urine may result in specimen dilution that may reduce test sensitivity. Female patients should not cleanse the labial area prior to providing the specimen. Thus, a urine sample collected from a female for Chlamydia/GC TMA cannot be collected at the same voiding event as that urine which would be intended for bacterial culture. Remove the cap of the APTIMA Urine Specimen Collection tube and transfer 2 mL of urine into the urine specimen transport tube using the disposable pipette provided. The correct volume of urine has been added when the fluid level is between the black lines within the clear pane on the urine specimen transport tube label. Collection Container: APTIMA Urine Specimen Collection Kit. PreservCyt (ThinPrep): Transfer 1 mL of PreservCyt (ThinPrep solution) into APTIMA Specimen Transfer tube (green label) or APTIMA Vaginal Swab Specimen Collection kit or Multi-Test Collection kit Collection tube (orange label).
