Chlamydia trachomatis (C. trachomatis) is one of the most prevalent preventable sexually transmitted diseases (STDs) in the world. In women, C. trachomatis infection can lead to long-term complications such as pelvic inflammatory disease (PID), and other related conditions such as ectopic pregnancies and even tubal factor infertility. These complications are preventable given early detection and clinical intervention, but these efforts are often hampered by asymptomatic silent infections, and non-compliance to screenings for STDs. Some women do not get tested out of concerns for violation of privacy, and fear of discomfort. Clinicians often use a multitude of tests to determine if a patient is infected by C. trachomatis, including a Polymerase Chain Reaction (PCR) test of First catch urine (FCU) samples. However, these tend to be inconvenient to store and transport, as they carry risk of spillage and have stringent refrigeration requirements. Moreover, given the gold-standard recommendations set forth by the Centres for Disease Control (CDC), the current technique can be inconvenient in remote areas where refrigeration and transport may not always be reliable. The current study therefore looks at the potential of a self-collected vaginal swab device that relies on Nucleic Acid Amplification Tests (NAATs), is dry-stored, and does not require refrigeration, to detect the presence of C. trachomatis in women. The study found evidence to suggest that the self-collection device has the potential to aid clinicians in the diagnosis of C. trachomatis in women when compared to doctor-collected vaginal discharge samples as the designated standard, FCU, and blood serology. Moreover, as a self-collection device it has the potential to break down some of the barriers to STD screening especially in young women, such as violation of privacy. The device therefore has a potential to encourage screening and therefore a potentially effective tool in the fight against the spread of preventable sexually transmitted diseases.
