Trichomonas vaginalis infection is the most prevalent treatable sexually transmitted infection (STI) in the world. An accurate point-of-care (PoC) molecular test would enable patients to be tested and treated for T vaginalis in a single visit to the genitourinary medicine clinic, community STI clinic, pharmacy or doctor's office. In this report, we describe a rapid prototype assay for T vaginalis designed for use in conjunction with the Atlas io PoC platform, and initial verification of its performance using 90 clinical samples.
