title: [Detection of Chlamydia trachomatis from urine sediment by PCR diagnostic reagent kit].
abstract: Chlamydia trachomatis detection by both swab CHLAMYDIAZYME and urine sediment AMPLICOR were performed on 61 males and 54 females who were suspected to have C. trachomatis genital infection (CTGI). Positive agreement between swab CHLAMYDIAZYME and urine sediment AMPLICOR was good, 96.9% in males and 96.6% in females. Negative agreement was 100% in males and 84.0% in females. "Swab CHLAMYDIAZYME positive-Urine sediment AMPLICOR negative specimen" were not obtained. "Swab CHLAMYDIAZYME negative-urine sediment AMPLICOR positive" resulted in four females who were finally diagnosed to have CTGI by repeated specimens on CHLAMYDIAZYME. Positive result by AMPLICOR was obtained on un-spun urine specimen that was in agreement with the laboratory result that the sensitivity of AMPLICOR reaches one thousand fold of CHLAMYDIAZYME. Detection on every separately collected urine specimen of one urination showed AMPLICOR positive all through the last cup specimen in both male and female. Those results seem to certify the reliability of C. trachomatis detection by urine sediment AMPLICOR. False negative by interference substance in urine and false positive by contamination were not experienced. On asymptomatic young male and female, positive rates of urine sediment AMPLICOR were 7.5% in male and 12.1% in female which are far more than the positive rate obtained by CHLAMYDIAZYME. Non invasive C. trachomatis detection method applicable to asymptomatic female is needed for control of CTGI. C. trachomatis detection could be facilitated by non invasive urine sediment AMPLICOR.
