The infection is systemic and the disease is characterized by periods of latency. From Wikipedia, the free encyclopedia. The sensitivity of syphilis assays in detecting different stages of early syphilis. Therefore, detection of antibodies to nontreponemal antigens, such as cardiolipin a lipoidal antigen released by host cells damaged by T pallidum may help to differentiate between active and past syphilis infection. Reference Values Negative. Specimen Type Serum. In the test, gelatin particles are sensitized with T.

    In the setting of a positive syphilis IgG screening result and a negative RPR, a positive TP-PA result is consistent with either 1) past, successfully treated syphilis. treated for syphilis, TPA+/RPR-/TP-PA+ results together suggest a late latent infection and pallidum antibody test (TPPA), suggests exposure to syphilis.

New York Churchill Livingstone,pp Syphilis is categorized by an early primary infection in which patients may have non-specific symptoms, and potentially, genital lesions. Useful For An aid to resolve discrepant results between screening treponemal eg, enzyme immunoassay [EIA], multiplex flow immunoassay and nontreponemal eg, rapid plasma regain assays.

    The results of TP-PA assist in determining whether the results of a screening treponemal test are truly or falsely positive.

    In Principles and Practice of Infectious Diseases. Sex Transm Dis. Specimen Type Serum. Recently, the Centers for Disease Control and Prevention recommended that specimens testing positive by a screening treponemal assay and negative by RPR be tested by a second treponemal test eg, TP-PA. Syphilis screening at Mayo Clinic is performed by using the reverse algorithm, which first tests sera for Treponema pallidum specific IgG antibodies using an automated multiplex flow immunoassay MFI.
