Instructions Aptima (Gen-probe) Endocx/ureth swab - cobas(R) PCR Female Swab Sample Kit
Collection: Collecting an endocervical swab specimen for use in NAAT testing procedures involves the use of a speculum and includes the use of two swabs one for initial cleaning of the cervix to remove excess mucus from the cervical os and surround mucosa (this swab should be discarded), and a second for specimen collection. 1) Use one of the swabs in the collection kit to clean the mucous from the cervix. 2) Discard the cleaning swab. 3) Use a second swab to collect the specimen by insertion of the swab into the endocervical canal followed by gentle rotation of the swab. 4) Withdraw the collection swab while avoiding contact with the vaginal mucosa. 5) Place the swab into the PCR media tube and break the shaft at the score line. 6) Do not submit both swabs. 7) Tightly and securely seal the PCR media tube. 8) Mixed to ensure the collected specimen has been thoroughly exposed to the transport media which contains nucleic acid stabilizing agents.
