Immunoassay for the qualitative determination of total antibodies against Treponema pallidum
Intended to aid in the diagnosis of syphilis infection in conjunction with nontreponemal tests and clinical signs and symptoms
Syphilis is caused by the intracellular Gram-negative spirochete bacterium Treponema pallidum subspecies pallidum.1 In 2023, over 200,000 new cases were reported in the US, the greatest number of cases since 1950.2
Most people with syphilis are asymptomatic, but if untreated the infection can cause significant complications.3 Although syphilis is usually transmitted sexually, it can also be transmitted from mother to fetus with over 3,700 pregnancies affected in the US each year.4 However, if diagnosed in the early stages, syphilis can be successfully treated and congenital syphilis prevented.5,6
Serologic tests like the Elecsys® Syphilis assay are the method of choice for the reliable detection of total antibodies against Treponema pallidum in clinical routine samples.7
