RECRUITING

NCT07089836

This Study Evaluates the ALPCO Syphilis-T and Syphilis-NT CLIA Kits for Detecting Syphilis Antibodies in Serum and Plasma. Samples From At-risk, HIV-positive, Pregnant, and Healthy Individuals Will Assess Assay Performance Versus Established Comparator Tests.

This study will evaluate the clinical performance of two investigational diagnostic kits developed by ALPCO: the Syphilis-T CLIA Kit and the Syphilis-NT CLIA Kit. These kits are designed to detect antibodies to Treponema pallidum and non-treponemal lipoidal antigens, respectively, in human serum and plasma using the automated KleeYa platform. The study will collect and analyze blood samples from individuals suspected of having syphilis, those at high risk, HIV-positive patients, pregnant individuals, and healthy controls. The aim is to determine the kits' Positive Percent Agreement (PPA) and Negative Percent Agreement (NPA) compared to established reference assays.

Neutralizing Power of Serum Antibodies - 2

Severe forms of COVID-19 and Monkeypox affect immunocompromised and comorbid individuals. Vaccination and monoclonal antibody therapies induce neutralizing antibodies. This neutralizing power is recognized as a correlate of protection against a new infection. This study aims to describe the neutralizing power of serum and nasal antibodies over time, in relation to SARS-CoV-2 and MPXV vaccines or treatments received.
