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

To evaluate the clinical performance of each analyte (HIV, HBsAg, and Syphilis) on the TruPlex HIV/HepB/Syphilis Rapid Test (TruPlex Test) using capillary blood (fingerstick), EDTA whole blood, EDTA-plasma, and SST-serum samples collected by trained operators at point-of-care settings. Additionally, to evaluate the usability of the TruPlex test through: structured usability assessments, via a questionnaire, completed by trained operators in point-of-care settings.

About this study

A prospective study 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 healthcare professionals. The collected capillary and EDTA whole blood samples will be tested on TruPlex Tests. Subsequently, EDTA whole blood and SST whole blood samples will be further processed to obtain plasma and serum, respectively, for testing on the TruPlex. Additional venous whole blood samples will be collected and sent to the National Serology Reference Laboratory (NSRL) 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.

  • Subject is able to speak/read/write English or a translator is available
  • Subject is getting tested for HIV, and/or Syphilis, and/or Hepatitis B for one or more of the following reasons:
  • At risk for any one of the target diseases
  • Having signs or symptoms indicative of the target diseases
  • Routine testing
  • Note: Subjects who are pregnant and re-infected are eligible to participate
  • Unknown HIV or known HIV positive status with less than 12 months of Anti-Retroviral Treatment (ART).
  • Subject is willing to provide the fingerstick blood sample(s) and whole blood samples collected through venous blood draw (approximately 16 ml) required for the study.
  • Subject willing to participate in the study site's standard of care counselling and testing program and receive the study site's standard of care test results

Exclusion criteria

  • Subject has a bleeding disorder
  • Subject is currently undergoing Syphilis treatment
  • Subject has received any experimental HIV vaccine
  • Subject received HBV vaccine within the last 7 days
  • Known HIV positive subjects and currently on ART for 12 months or longer

Treatment and study plan

TruPlex HIV/HepB/Syphilis Rapid Test

Device

A rapid in vitro diagnostic device designed to determine HIV, Syphilis and Hep B infection status.

Primary outcomes

  1. Performance Evaluation

    Time frame: 6 months

    The study will assess the sensitivity and specificity of the TruPlex Test for detecting:

    • HIV-1 and HIV-2 antibodies
    • Syphilis antibodies
    • Hepatitis B surface antigen (HBsAg)

    Capillary blood, EDTA whole blood, EDTA-plasma and SST-serum samples will be tested using the TruPlex Test. Performance will be compared against approved, current on-market assays for the detection of HIV 1/2 antibodies, Syphilis antibodies, and HBsAg.

Secondary outcomes

  1. Usability Evaluation

    Time frame: 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.
