New Chlamydia Test Quicker and More Cost-effective Than Current Tests

Chlamydia trachomatis infection is the most common sexually transmitted bacterial infection in the world but often has no symptoms. Yet, if left undiagnosed and untreated, it can result in complications such as pelvic inflammatory disease, ectopic pregnancy, and infertility.
Developed countries, including the UK, have national screening programmes in place which tend to use nucleic acid amplification tests to diagnose infection. These tests are more sensitive than the currently available rapid tests, but require costly machines in addition to trained staff and results can take up to two weeks.
In contrast, screening programmes for Chlamydia are almost nonexistent in the developing world.
So researchers assessed the performance of a new Chlamydia Rapid Test compared to the currently available nucleic acid based tests (polymerase chain reaction and strand displacement amplification tests).
Over 1,300 women aged between 16 and 54 years attending one of three clinics in the UK were included in the study.
An information sheet was given to each participant explaining how to collect the vaginal swabs. Swabs and urine cups were then provided and each participant was surveyed about sample collection methods and preferences.
The new Chlamydia Rapid Test achieved relatively high diagnostic sensitivity (83.5%) compared with the more complicated nucleic acid based tests. It also provided results within 30 minutes, allowing all positive individuals to be offered treatment while still at the clinic.
