Serologic Testing for Syphilis

Syphilis — Incidence

April 2011

The incidence of disease is of particular importance when selecting an assay or testing algorithm, as the positive predictive value of a laboratory method is impacted by how prevalent the disease is in the population. As you can see on this slide, the incidence of syphilis has declined significantly over the past 60 years.
