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)
