Ordering Recommendations

This test is not recommended for evaluation of suspected sexual abuse or for other medico-legal indications

Forms & Information

Clinicians: specimen collection instructions
     Clinician collect: Anorectal
     Clinician collect: Endocervical
     Clinician collect: Vaginal

Patient Preparation

The presence of mucus in endocervical specimens may cause false negative test results

Collect

Preferred:
   cobas PCR Media Uni Swab - vaginal, cervical, oropharyngeal (throat) or anorectal








Also preferred:

    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.

Also preferred:
   ThinPrep PreservCyt - vaginal, cervical or endocervical

Acceptable but not preferred:
