A Study to Evaluate Performance, Usability, and Contrived Result Interpretation of TruPlex HIV/HepB/Syphilis Rapid Test
A Study to Evaluate the Performance, Usability, and Contrived Result Interpretation of TruPlex HIV/HepB/Syphilis Rapid Test by Trained Personnel at Near-Patient and Point-of-Care Settings
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.

Detaljerad beskrivning
The study is designed to evaluate TruPlex Test when used by trained users.
Non-invasive samples (fingerstick, EDTA whole blood, EDTA-plasma, and SST-serum) will be collected and tested on TruPlex tests by on-site trained operators. Capillary (fingerstick) whole blood and EDTA whole blood samples will be collected by healthcare professionals. The collected capillary and EDTA whole blood samples will be tested on the TruPlex tests. Subsequently, the EDTA whole blood and SST whole blood samples will be further processed to obtain EDTA plasma and SST serum, respectively, for testing on the TruPlex. Blood samples will be collected and sent to the central laboratory for confirmatory testing (HIV, Syphilis and HBsAg) using approved on-the-market assays. Any remaining samples will be stored for further discrepancy testing or future research use.
A minimum of two TruPlex Test lots will be used for the study.
The following studies will also be performed:
Usability evaluation to assess user experience and success in label comprehension of the TruPlex test via a questionnaire.
Contrived result interpretation with a minimum of 15 intended users across a minimum of 3 clinical sites. Participants will be trained healthcare professionals that are paid employees of the study sites. Participants will have prior experience using rapid tests. Participants will evaluate a set of contrived tests to determine and document if intended users can successfully interpret various TruPlex Test results that include - strong positive, weak positive, negative, and a range of invalid results.

Usability Evaluation
Tidsram: 6 months
|
Usability will be determined via a questionnaire completed by trained personnel who used the device during testing.
The usability questionnaire will use a scale of one (1) to 5 (1 - very difficult/very unlikely to 5 - very easy/very likely), with a rating of 3 being satisfactory.

Contrived result interpretation evaluation
Tidsram: 6 months
|
Trained operators will evaluate a panel of contrived (mock) TruPlexdevices.
These devices are designed to represent a comprehensive range of test outcomes, including strong positives, weak positives, negatives and invalid results.
Operators will interpret the results of the mock devices and record their interpretations which will be compared to the correct interpretation of the device.
