Enzyme Immunoassay (EIA) - Use:
Detection of Trichomas vaginalis antigen as an indicator of trichomonal infection
Intended for use in patients with symptoms of vaginosis/vaginitis or suspected exposure to the Trichomonas pathogen - Clinical Significance:
Trichomonas infection is responsible for the most common, non-viral sexually transmitted disease (vaginitis or trichomoniasis) worldwide. Trichomoniasis is a significant cause of morbidity among all infected patients. Effective diagnosis and treatment of Trichomonas infections have been shown to eliminate symptoms. Conventional identification procedures for Trichomonas from vaginal swabs or vaginal washes involve the isolation and subsequent identification of viable pathogens by wet mount microscopy or by culture, a process that can take 24-120 hours. Wet mount microscopy has a reported sensitivity of 58% versus culture. The OSOM® Trichomonas Rapid Test is available for the qualitative detection of Trichomonas vaginalis antigens from vaginal swabs or from the saline suspension submitted for direct wet mount examination. This antigen assay is more sensitive than a wet mount and is less costly than a molecular assay for trichomonas.
