Elecsys® Syphilis


Confidence in all stages of treponemal infection

  • Syphilis is caused by the intracellular Gram-negative spirochete bacterium Treponema pallidum subspecies pallidum
  • In 2012, approximately 12 million new cases of infection were reported.
  • Most people with syphilis are asymptomatic, but if untreated the infection can cause significant complications.
  • Although syphilis is usually transmitted sexually, it can also be transmitted from mother to fetus with an estimated 1.5 million pregnancies affected globally each year. However, if diagnosed in the early stages, syphilis can be successfully treated and congenital syphilis prevented.
  • Syphilis can be transmitted through blood transfusions.
  • Serological tests like the Elecsys Syphilis assay are the method of choice for the reliable detection of Treponema palladium infections.
