title: Evaluation of a new particle gel immunoassay for determination of antibodies against Treponema pallidum.
abstract: A new particle gel immunoassay (DiaMed AG, Cressier sur Morat, Switzerland) with three recombinant Treponema pallidum antigens was evaluated with serum samples from patients with syphilis (n = 124) and patients without syphilis (n = 490). It proved to be a simple, rapid (20 min), and useful test with sensitivity, specificity, and positive and negative predictive values of 91.9, 99.8, 99.2, and 98%, respectively.
