Performance evaluation of a new rapid urine test for chlamydia in men: prospective cohort study.

Objective: To evaluate the performance of a rapid test for chlamydia with first void male urine samples as a potential tool for diagnosis and screening of chlamydial infection in men.

Design: Evaluation of test performance in prospective cohort study. Settings A young people's sexual health centre (site 1) and a genitourinary medicine clinic (site 2) in the United Kingdom.

Sample preparation: a challenge in the development of point-of-care nucleic acid-based assays for resource-limited settings.

Currently available nucleic acid testing (NAT)-based assays are complex and time-consuming, and they require expensive instrumentation and dedicated laboratory spaces for sample preparation as well as for amplification and detection of the nucleic acid target. Reagents required for these tests are also expensive and must be transported and stored refrigerated or frozen. These characteristics have limited the use of such assays for point-of-care (POC) testing, especially in resource-poor settings.

Optimal method of collection of first-void urine for diagnosis of Chlamydia trachomatis infection in men.

First-void urine (FVU) is the preferred specimen for the diagnosis of urogenital Chlamydia trachomatis infection in men. We have developed FirstBurst, a urine collection device that collects the first 4 to 5 ml of FVU and yields a specimen with a sixfold higher C. trachomatis organism load than the regular urine cup by quantitative PCR (32,533 versus 5,271 plasmids/ml; P < 0.

New point of care Chlamydia Rapid Test--bridging the gap between diagnosis and treatment: performance evaluation study.

Objective: To evaluate the performance of a new Chlamydia Rapid Test with vaginal swab specimens as a potential tool for chlamydia diagnosis and screening.

Design: Performance evaluation study. Settings A young people's sexual health centre (site 1) and two genitourinary medicine clinics (sites 2 and 3) in the United Kingdom.

Prevalence of Chlamydia trachomatis infection among low- and high-risk Filipino women and performance of Chlamydia rapid tests in resource-limited settings.

The prevalence of urogenital Chlamydia trachomatis infection was determined with a PCR-based test of women from low- and high-risk populations in Iloilo City, Philippines, between August 2002 and March 2006. Two rapid tests for C. trachomatis, Clearview Chlamydia MF and the Chlamydia Rapid Test (CRT), were also evaluated in these resource-limited settings.
