    The rapid plasma reagin test (RPR test or RPR titer) is a type of rapid diagnostic test that looks for non-specific antibodies in the blood of the patient that may indicate an infection by syphilis or related non-venereal treponematoses. It is one of several nontreponemal tests for syphilis (along with the Wassermann test and the VDRL test).

    For primary syphilis, TPPA has a sensitivity of 85% to 100%, and a specificity of 98% to 100%. [2] In secondary and late-latent syphilis, TPPA has a sensitivity of 98% to 100%. [2] Antibodies against other treponemal organisms, such as the T. pallidum subspecies endemicum, pertenue, or carateum, can cause false positive results.

    The Venereal Disease Research Laboratory test (VDRL) is a blood test for syphilis and related non-venereal treponematoses that was developed by the eponymous US laboratory. The VDRL test is used to screen for syphilis (it has high sensitivity ), whereas other, more specific tests are used to diagnose the disease.

    With nontreponemal tests, false-positive reactions can occur for a large number of reasons, the most common of which is other infections, both viral and bacterial. Additionally these tests may show false-negative when the patient's antibody titer is very high due to a hook effect (also called a prozone effect).

    Syphilis is typically spread through direct contact with a syphilis sore, known as a chancre, during vaginal, anal or oral sex. It can also be passed from a pregnant person to a child during birth.

  8. Fluorescent treponemal antibody absorption test - Wikipedia

    en.wikipedia.org/wiki/Fluorescent_treponemal...

    The fluorescent treponemal antibody absorption (FTA-ABS) test is a diagnostic test for syphilis.Using antibodies specific for the Treponema pallidum species, such tests would be assumed to be more specific than non-treponemal testing such as VDRL but have been shown repeatedly to be sensitive but not specific for the diagnosis of neurosyphilis in cerebrospinal fluid (CSF).

  9. Treponema pallidum - Wikipedia

    en.wikipedia.org/wiki/Treponema_pallidum

    Treponema pallidum, formerly known as Spirochaeta pallida, is a microaerophilic, gram-negative, spirochaete bacterium with subspecies that cause the diseases syphilis, bejel (also known as endemic syphilis), and yaws. [1] It is known to be transmitted only among humans and baboons. [2]
