简要总结
This study is designed to compare the performance of the NOWDx Syphilis Test to a currently marketed device. The intent is to show the rapid test device is comparable to the currently marketed device. The NOWDx Syphilis Test is intended for qualitatively detecting the presence or absence of human antibodies to syphilis in human whole blood to aid in the diagnosis of infection caused by Treponema pallidum.
详细描述
The objective of this study is to establish the performance characteristics of the NOWDx Syphilis Test based on comparison to the BioRad Bioplex 2200 series Syphilis Total (IgG/IgM), Wampole Impact RPR Test Kit, and to the Serodia Treponema pallidum particle agglutination assay (TP-PA).
The external clinical study along with in-house analytical studies will demonstrate the efficacy of the NOWDx Syphilis Test as an aid in the diagnosis of syphilis infection for at home testing and point of care testing sites. Participants will self test and be tested by Clinical Laboratory Improvement Amendments (CLIA) Waived operators with the NOWDx Syphilis Test at independent sites in WA, AZ, and NV. Two sample types will be tested with the NOWDx Syphilis Test for each participant: fingerstick whole blood and venous whole blood. Sera from each participant will be tested at an independent reference laboratory.
The NOWDx Syphilis Test will be evaluated in diverse populations of sexually active persons who self-select for syphilis testing and expectant mothers.

结局指标
主要结局
Compare serological status to comparator method
时间窗: through study completion, an average of 6 months
The comparator method used in this study is an algorithm comprised of results from three different commercially available syphilis assays: an FDA-cleared treponemal immunoassay, an FDA-cleared non-treponemal assay (RPR assay) and a second treponemal assay (TP-PA).
Evaluate test reproducibility by lay users
时间窗: through study completion, an average of 6 months
Test lay user reproducibility using prepared samples for % agreement with expected results.
