Urinary leukocyte esterase screening for asymptomatic sexually transmitted disease in adolescent males.

The objective of this study was to evaluate the effectiveness of urinary leukocyte esterase on random urine specimens as a screening test for chlamydial and gonococcal urethral infections in asymptomatic males. Random urine specimens were obtained on 106 consecutive asymptomatic adolescent males during intake physical examination at a residential vocational training program. Results of urinary leukocyte esterase were compared to those of urethral cultures for Chlamydia trachomatis and Neisseria gonorrhoeae. Five subjects had positive chlamydia cultures, three subjects had positive gonococcal cultures, and one patient had positive cultures for both organisms. Sixteen subjects had leukocyte esterase tests reported as "trace" or greater. When compare to positive culture results for either Chlamydia or gonorrhea, urinary leukocyte esterase activity had a sensitivity of 78%, specificity of 91%, and positive predictive value of 44%. A random urine specimen for urinary leukocyte esterase activity is a cost-effective screening method for chlamydial and gonococcal urethral infections in asymptomatic adolescent males.[1]
