Clinical laboratories primarily use the reverse algorithm to screen for syphilis; however, the Centers for Disease Control and Prevention recommend the traditional algorithm....
Screening is performed on a blood sample using the standard or reverse syphilis testing algorithm. Overview of syphilis screening [6][28] Indications for initial screening Indications and frequency of repeat screening Screening for adolescents and adults Individuals with risk factors for syphilis inf...
labor, and costs. Reverse screening test sera first by automatable treponemal enzyme and chemiluminescence immunoassays (EIA/CIA), followed by testing of reactive sera with a nontreponemal test. Results of the first direct comparison of traditional and reverse screening suggest reverse screening may not...
Context: -Syphilis serology screening in laboratory practice is evolving. Traditionally, the syphilis screening algorithm begins with a nontreponemal immunoassay, which is manually performed by a laboratory technologist. In contrast, the reverse algorithm begins with a treponemal immunoassay, which can be...
reverse syphilis diagnostic algorithms during general health checkups. In total, 1000 blood specimens were obtained from 908 men and 92 women. As a result, the reverse screening algorithm could detect the subjects with possible latent syphilis who were not detected by the traditional algorithm [71]...
n Two different algorithms, which combine a treponemal with a nontreponemal test, are used to aid in the diagnosis of syphilis. In recent years, the reverse algorithm has become increasingly utilized compared to the traditional algorithm due to reduced screening labor costs and improved ...
Darkfield microscopy is considered a point of care test for early syphilis, especially primary syphilis [1].(LE: 1a) Serology Two-step algorithm preferred over 1-step algorithm.(LE: 1a) The reverse screening algorithm is more sensitive and ensures better detection of late syphilis, but has more...

Second, the review did not address the comparative screening accuracy of traditional vs reverse sequence algorithm testing; however, to our knowledge, no studies have compared these 2 testing algorithms in prenatal care. Third, the benefit of penicillin G for the treatment of syphilis is well ...
