Key facts

  • Deprecated PhenX measure - assay for syphilis
  • PhenX measure - assay for syphilis
  • This is a bioassay to measure past or current infection with Treponema pallidum, the bacterium that causes syphilis. The measure determines whether a participant has been infected with Treponema pallidum, the bacterium that causes syphilis. The primary and secondary stages of syphilis are infectious and associated with fetal wastage and the congenital syphilis syndrome. They also increase the risk of human immunodeficiency virus (HIV) acquisition and transmission, while latent disease may be associated with the progression of HIV disease to acquired immune deficiency syndrome (AIDS) and more prominent neurologic disease in HIV-infected persons. The tertiary stage is associated with a vasculitis that may cause neurologic and cardiovascular manifestations and other chronic problems (National Health and Nutrition Examination Survey [NHANES] 2003-2004 Data Documentation).
