A Study to Evaluate Performance, Usability, and Contrived Result Interpretation of TruPlex HIV/HepB/Syphilis Rapid Test

The objectives of this study are as follows: To evaluate the clinical performance of the TruPlex test using capillary blood, EDTA whole blood, EDTA plasma, and SST serum samples collected by trained operators in point-of-care settings To evaluate the usability of the TruPlex test through: Structured usability assessments, via a questionnaire, completed by trained operators in point-of-care settings. To assess user interpretation accuracy through a contrived result interpretation questionnaire, where intended users evaluate a set of pre-defined test results (e.g., strong/weak positives, negatives, invalids). To monitor test system reliability, including invalid rates.
