Starter reagents are added, and a light signal is produced from a flash chemiluminescence reaction if antitreponemal antibodies are present. We conclude that the LIAISON CLIA demonstrated excellent sensitivity and specificity when evaluated as a confirmatory test and as a screening test for syphilis among various patient populations, including specific populations with reportedly increased rates of false-positive nontreponemal test results. Sexually transmitted disease surveillance, Phone: The spirochete Treponema pallidum subsp.

  • Evaluation of the LIAISON Chemiluminescence Immunoassay for Diagnosis of Syphilis
  • Treponema DiaSorin

  • Addition of the DiaSorin LIAISON® Treponema Assay to the LIAISON® technology for the qualitative detection of total antibodies of any class (IgG/IgM). The LIAISON® Treponema Assay uses chemiluminescent immunoassay (CLIA) technology on the LIAISON® Analyzer family for the qualitative.

    Treponemal tests, such as the LIAISON® assay, EIAs, FTA-ABS and TP-PA, detect antibodies to Treponema pallidum and therefore indicate the specific cause of.
    Public Health 3 : The overarching goal of the work described herein is to investigate strategies for improving the detection and surveillance of multidrug-resistant Neisseria gonorrhoeae MDRNG and syphilis, two important sexually transmitted infections. More Information Less Information.

    Clin Vaccine Immunol.

    When the results for all samples in this study were combined, sensitivity and specificity were calculated for the entire group of 2, samples. Unbound components are again washed away, and tetramethylbenzidine enzyme substrate is added.

    pallidum-specific assay (Diasorin, Stillwater.
    The CLIA, like other treponemal assays, does not differentiate recent versus remote or previously treated infections, and therefore, clinical history is important in determining the significance of the test result.

    Syphilis progresses through multiple clinical stages, with characteristic features including the painless and indurated chancre of primary syphilis, followed by spirochetemia with systemic symptoms and a rash in secondary syphilis.

    Hooper, N. Based on the algorithm outlined in Fig. This explanation is a possibility for seven of nine samples sent for routine testing, two of seven samples from apparently healthy adults, and two of five samples from HIV-positive patients that were positive by the CLIA and negative by the algorithm, as they were also positive by the T.

    Sexually transmitted disease surveillance, We also thank Carolyn Chaffin for her administrative expertise.

    Thus, the index value for a patient's specimen is calculated by comparing the patient's light signal RLU to a working curve from the light signals RLU obtained from calibrators.

    The rate of primary and secondary syphilis reported in the United States decreased during the s, with the rate reported in being the lowest since reporting began in 1.

    Results between 0. Storni, and R. With the result according to the testing algorithm as the standard for comparison, the overall relative sensitivity of the assay was The CLIA was evaluated as a screening test for various patient populations and was also evaluated as a confirmatory test for sera which were RPR positive.

    Fax: However, this group of samples seems to include too few samples negative for syphilis, that is, samples with false-positive RPR test results, to thoroughly evaluate the ability of the assay to resolve false-positive nontreponemal test results.

    As with all other tests for syphilis, its interpretation must be combined with clinical findings and results from other tests for optimal use.
