ABSTRACT
to determine the prevalence of Chlamydia trachomatis and to compare the abilities of three different techniques of collecting specimens [urine, vaginal swab, and endoeervical swab] to identify a positive specimen. Cross-sectional. Setting:
Al Zahraa University Hospital a total of 70 women were enrolled in the study, the women provided first-void urine and self-collected vaginal swabs. The overall prevalence of genital C. trachomatis infection was 20.0% and 70% in women consulting without [G0] and with [G1] genital symptoms, respectively [Table 2]. The rate of detection of Chiamydia using PCR in urine samples did not differ significantly between the 2 groups although it showed a higher detection rate in the other sympyomatizing cases. The detection rate in vaginal introital swabs and endocervical swabs were significantly higher in cases than control, p=0.045 and 0.031 respectively. When both vaginal and endocervical swabs are combined together the difference was extremely significant [p=0.0016]. Self-collected vaginal swabs identified the highest number of positive test results among single specimens, with the combined cervix-vagina results identifying the highest number of positiveresults:
