The United States Food and Drug Administration (FDA) granted marketing authorization for the first home-based, nonprescription diagnostic test for chlamydia, gonorrhea, and trichomoniasis in women. This announcement came on Friday. This means that women with or without symbols can now use this test for these three sexually transmitted infections (STIs). The results are delivered in about 30 minutes.It is a single-use, at-home test which includes a self-collected vaginal swab and a powered testing device. It provides a secure communication with an app it is connected to. Once the swab collection is completed, the test results are displayed on the app.This has come after the first at-home syphilis test which had come last year and authorization of the first diagnostic test for chlamydia and gonorrhea with at-home sample collection in 2023. It was also the first FDA-authorized test with at-home sample collection for an STI other than HIV.How was it approved?The approval was based on the data that showed on Visby Medical Women's Sexual Health Test. It has correctly identified 98.8 and 97.2 percent of negative and positive Chlamydia trachomatis samples; 99.1 and 100 percent of negative and positive Neisseria vaginalis samples, and 98.5 and 97.8 percent of negative and positive Trichomonas vaginalis samples.The FDA also noted that women who get positive results must consult with a physician. FDA also notes that those with symptoms or recent STI exposure or just concerned should go for additional testing, if required. The main risk of using this device could be the possibility of false negative results, which could delay treatments, or the possibility of false positive results which could lead to unnecessary treatment."Expanding access to tests for sexually transmitted infections is an important step toward earlier and increased diagnosis, which can result in increased treatment and reduced spread of infection," said Courtney Lias, Ph.D., director of the Office of In Vitro Diagnostic Devices in the FDA Center for Devices and Radiological Health.What Is Chlamydia?As per the World Health Organization (WHO), it is a preventable and curable STI which is caused by bacterium Chlamydia trachomatis. This is primarily transmitted through vaginal, oral, and anal sex. In 2020, there were around 128.5 million new chlamydia infections, especially among adults, around the age of 15 to 29, globally.The major cause of concern is that it is often asymptomatic. However, there are symptoms, which mainly includes unusual urethral and vaginal discharge. If left untreated, it could lead to serious health problems, including pelvic inflammatory disease and infertility in women. It can also increase the risk of HIV infection.What Is Gonorrhoea?As per the National Health Service (NHS), UK, gonorrhoea is an STI, passe don through unprotected sex. It could be treated with antibiotics. Here too, symptoms usually do not appear. However, if they do, it starts around 2 weeks after the infection. In some cases it may take months for symptoms to appear.What Is Trichomoniasis?It is also a common STI among women of reproductive age, notes WHO. It is caused by protozoan Trichomonas vaginalis. It is treatable and curable.
