Abstract
A method of detecting antibodies to syphilis antigens includes providing a syphilis detection kit having a screening solid-phase platform with a screening portion coated with non-treponemal syphilis antigens. The screening portion is fabricated by initially dissolving cholesterol in an organic solvent and further diluting the dissolved cholesterol in an ethanol solution comprising cardiolipin and lecithin to form an antigen solution, permitting the antigen solution to evaporate at the screening portion and at least partially coating the screening portion with an antigen coating, and stabilizing the antigen coating into a syphilis antigen complex by overcoating the antigen coating with an overcoat solution comprising an inert protein.
