In diagnosing suspected syphilis cases, the reverse algorithm and ECDC algorithms utilizing treponemal tests as the initial step were found to be superior to the traditional algorithm. Our study demonstrates that treponemal antibody tests are superior when employed as the initial step in diagnosing syphilis in patients with latent syphilis among suspected cases. Nontreponemal tests should be used solely to evaluate disease activity and response to therapy.
