bUse of a new collection kit for vaginal and cervical sampling was reported as easy by the majority of 692 women and not uncomfortable (by 87.4% of those >25 years old and 78.8% of those <25 years old). By Aptima testing, patient-and physician-collected samples agreed strongly for Chlamydia trachomatis (99.6% to 99.3%; â«Ű⏠0.93 to 0.89) and T. vaginalis (99.6% to 98.9%; â«Ű⏠0.97 to 0.78).
Chlamydia trachomatis and Trichomonas vaginalis are common sexually transmitted infections (STI) of the lower genital tract. Control programs require screening to detect and treat asymptomatic infections to prevent upper tract complications due to C. trachomatis and persistent T. vaginalis infections and related sequelae.Detection of infections requires the collection of endocervical or vaginal samples during a pelvic examination or selfcollection of first-void urine or vaginal samples. If self-swabbing is to be used for screening, the procedure and collection device will be more acceptable if the device is easy to use and is not uncomfortable.A new specimen collection and transportation (SCT) kit (Hologic/Gen-Probe Incorporated) was developed for sampling the cervix and vagina for STIs and transporting the specimens to the laboratory to be tested by Aptima transcription-mediated amplification assays. The collection device is a tapered brush similar in appearance to collection brushes used for collecting cervical cells for human papillomavirus testing (1, 2). The objective was to determine the ease and comfort of using the SCT when women selfcollected a vaginal sample and to compare the new SCT kit for detection of C. trachomatis and T. vaginalis from self-collected vaginal SCT (S-VSCT) and physician-collected vaginal and cervical samples.A total of 708 women (580 attending a gynecology clinic and 128 attending a street youth health clinic) signed consent for the collection of 2 vaginal and 3 cervical samples as outlined in the consent form, which was approved by St. Joseph's Healthcare and Juravinski Hospital Research Ethics Boards in Hamilton, Ontario, Canada. Each patient self-collected a vaginal sample and then answered a questionnaire concerning ease and comfort of collection using the new SCT kit. The physician then collected a vaginal sample (P-VSCT) and, after insertion of a speculum, collected PreservCyt (PC) L-Pap, cervical SCT (CSCT), and SurePath (SP) L-Pap endocervical samples. The PC L-Pap sample was always collected first as the standard of care for cervical cytology. L-Pap samples were collected with a cervix broom placed into the manufacturer's medium. The PC L-Pap sample was processed for cytology, and the remainder of the sample was sent with the other samples to the Infections Research Laboratory (IRL) at St. Joseph's Healthcare, where they were tested within 72 h by Aptima Combo 2 (AC2) for C. trachomatis and Aptima T. vaginalis (ATV) for T. vaginalis on a TIGRIS DTS instrument (Hologic/Gen-Probe Incorporated).Each patient was asked to complete a 5-point Likert scale questionnaire indicating whether it w...
