Products containing carbomers, including vaginal lubricants, creams and gels may interfere with the test and should not be used during or prior to collecting urogenital specimens.
Ordering Recommendations
This test is not recommended for evaluation of suspected sexual abuse or for other medico-legal indications.
Female patients: cobas PCR media Uni Swab - vaginal (preferred) or cervical
cobas PCR media Dual Swab - endocervical
NOTE: The woven swab is for cleaning. Discard it after use. Submit ONLY the flocked swab for testing. Samples including both swabs will be rejected.
cobas PCR Media Urine Kit - first catch urine
NOTE: The urine/media level should be between the two black lines on the cobas PCR Media urine tube label window (combined urine/media volume, about 4.3 mL)
Also acceptable: ThinPrep PreservCyt - vaginal, cervical or endocervical or 5 mL first catch urine in a sterile, leak-proof container (e.g., Power Cup) or in urine preservative tubes (e.g., grey-topped C&S Preservative Plus urine tube w/ Boric Acid preservative)
Male patients: cobas PCR Media Urine Kit - first catch urine
NOTE: The urine/media level should be between the two black lines on the cobas PCR Media urine tube label window (combined urine/media volume, about 4.3 mL)
Also acceptable: 5 mL first catch urine in a sterile, leak-proof container (e.g., Power Cup) or in urine preservative tubes (e.g., grey-topped C&S Preservative Plus urine tube w/ Boric Acid preservative)
Specimen Preparation, Minimum Volume
Urine in a sterile container must be transferred to a cobas PCR media urine tube within 24 hours of collection if kept at room temperature, or within 7 days if refrigerated.
For urine volumes less than about 4.3 mL, add a 1:1 ratio of urine to cobas PCR media in a clean tube. Write "1:1" on tube label, and initial.
