AB  - OBJECTIVE: We aimed to assess the performance of NAATs using vaginal specimens in comparison to other urogenital specimens in their ability to detect chlamydia and gonorrhea infection in women.DESIGN: Systematic review.DATA SOURCES: EMBASE and Ovid MEDLINE databases through 3 October 2017.ELIGIBILITY CRITERIA FOR SELECTING STUDIES: We included studies that tested samples from the vagina and ≥1 other site (cervix and/or urine) with ≥2 NAATs for chlamydia and ≥2 NAATs or 1 NAAT and culture for gonorrhoea for each site.DATA EXTRACTION AND SYNTHESIS: We compared the performance of NAATs on specimens taken from the vagina to those from the cervix or urine in diagnosing chlamydia and gonorrhoea infection in women based on patient infection status (PIS). We analysed the performance using vaginal specimens compared to PIS. Performance is defined as the sensitivity of a NAAT using a specimen site and PIS status of the patient. We assessed risk of bias using modified QUADAS-2.RESULTS: Nine publications met the inclusion criteria (eight for chlamydia; six for gonorrhoea) and were narratively reviewed. Pooled summary estimates were not calculated due to the variable methodology and PIS definitions. Tests performed on vaginal specimens accomplished similar performance to cervical and urine specimens for chlamydia (range of performance estimates: vaginal 65-100%, cervical 59-97%, urine 57-100%) and gonorrhoea (vaginal 64-100%, cervical 85-100%, urine 67-94%). Vaginal specimens were estimated to have a performance >80% for chlamydia and gonorrhoea infections in all but one study.CONCLUSIONS: Performance of the NAATs for chlamydia and gonorrhea detection using vaginal specimens was similar to that of cervical and urine specimens relativeto PIS. As vaginal samples have a higher acceptability and lower cost, the study can support clinical testing guidelines by providing evidence that vaginal samples are a suitable alternative to traditional test sites.
