Preferred Specimen
Urine or Vaginal, Urethral, Endocervical swab, Rectal, Pharyngeal and Eye


Minimum Volume
Urine specimens must be filled between the black lines on the collection tube.


Instructions
URINE: Urine MUST be submitted in Aptima(TM) Combo 2 Assay Urine Specimen Collection tube within 24 hours of collection.

URINE SPECIMEN INSTRUCTIONS:
Remove the cap of the Aptima(TM) Combo 2 Assay Urine Specimen Collection tube and transfer 2mL 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 INSTRUCTIONS:

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.
