Syphilis by DBS
To screen for or diagnose an infection with the bacterium Treponema pallidum, which causes syphilis, a sexually transmitted disease (STD).
Syphilis is an infection caused by the bacterium Treponema pallidum that is most often spread by sexual contact, such as through direct contact with a syphilis sore (chancre), a firm, raised, painless sore. The most common syphilis tests detect antibodies in the blood that are produced in response to a T. pallidum infection. Some methods that are used less commonly directly detect the bacterium or its genetic material (DNA).
