Serological testing is more commonly carried out on the mother and the infant to diagnose maternal and congenital syphilis. In the mother, a serologic diagnosis of syphilis is made using a nontreponemal test for syphilis such as the Venereal Disease Research Laboratory test or Rapid plasma reagin (RPR) followed by a treponemal test, such as the ...
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%.
