[Ligase chain reaction testing of pooled urine specimens to diagnose Chlamydia trachomatis infection].

Objective: The purpose of this study was to assess the utility and validity of pooling urine samples for molecular diagnosis of Chlamydia trachomatis infection.

Material And Methods: Of 1,220 urine samples collected from Mexican female and male adolescents, 305 pools were composed of fourth individual samples each, based on a calculation of optimal pool size. These were processed by ligase chain reaction (LCR) for the detection of C.
