About this study
Official title: ALPCO Syphilis-T (Treponema Pallidum) CLIA Kit and ALPCO Syphilis-NT (Non-Treponemal Lipoidal Antigen) CLIA Kit Blood Donation Protocol
This prospective, single-center study will collect blood from approximately 50 adult volunteers aged 22 years or older. Participants will provide informed consent, complete an eligibility review, and undergo one blood draw of approximately 20-50 mL.
The blood will be processed into serum and labeled with a study identification number. The serum may be used to prepare laboratory samples with defined antibody levels to support the development and performance evaluation of the ALPCO Syphilis-T and Syphilis-NT assays. All testing is for research purposes only. Individual test results will not be provided to participants or used for diagnosis or treatment.
Read the detailed description
Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. Laboratory diagnosis commonly includes treponemal tests, which detect antibodies specific to T. pallidum, and non-treponemal tests, which detect antibodies associated with cellular damage and may help assess disease activity.
Serum collected under this study will serve as a human serum matrix for preparing contrived specimens. These specimens may be created by adding characterized reactive serum or other appropriately characterized materials to produce predefined levels of treponemal or non-treponemal reactivity. Before use, the serum may be evaluated using appropriate reference or comparator methods to confirm its suitability.
The resulting specimens will support analytical and, when scientifically and regulatorily appropriate, clinical performance evaluations of the ALPCO Syphilis-T and Syphilis-NT assays. The specific preparation procedures, target reactivity levels, testing methods, and acceptance criteria will be defined in the applicable performance-study protocols.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ALPCO Syphilis-TDevice
Approximately 20-50 mL of whole blood will be collected during one study visit by qualified personnel using standard venipuncture procedures. The blood will be processed to obtain serum for research use in developing and evaluating the ALPCO Syphilis-T and Syphilis-NT assays.
ALPCO Syphilis-NT CLIA KitsDevice
Detection of antibodies to lipoidal antigens in human serum and plasma
| Study group | Role | What they receive |
|---|---|---|
| Adult Volunteer Blood Donors | Adult volunteers aged 22 years or older who provide one blood sample for serum collection and research use. Receives: Device: ALPCO Syphilis-T; Device: ALPCO Syphilis-NT CLIA Kits |
What is being measured
The primary outcome is the main question the study is designed to answer.
Number of Blood Specimens Successfully Processed Into Serum
The number of enrolled participants from whom approximately 20-50 mL of whole blood is successfully collected and processed into serum suitable for research use in the development and performance evaluation of the ALPCO Syphilis-T and Syphilis-NT assays.
Measured: Day 1, following the single study visit and serum processing
