[Urine samples for screening of asymptomatic Chlamydia trachomatis infection in young male recruits].

A prevalence rate of asymptomatic Chlamydia trachomatis infection among young Danish male military conscripts of 7.8% in 1989 and of 10.8% in 1992 is presented. A urine sample seems to be as valid a specimen type as a conventional urethral swab for demonstrating presence of Chlamydia trachomatis antigen by either ELISA (Enzyme-linked immunosorbent assay) or DFM (Direct Fluorescent Microscopy). The method is noninvasive and very suitable for screening young men in order to control urogenital Chlamydia trachomatis infection.
