The study enrolled young adult participants who self-presented at the clinic. A health-care professional demonstrated use of HIVST (directly-assisted approach) and then participants completed the self-test in the presence of the health-care professional (observed testing) who rated the participant's accuracy. After self-testing, participants provided feedback on acceptability and usability of the product.
Summary of findings
Overall, fidelity was high; 216 (96.4%) participants correctly completed the test and read and interpreted the HIV test result. There were eight (3.6%) user errors; six participants failed to prick their finger even though the lancet fired correctly. These participants correctly completed the test and read their results correctly on a second attempt. There were two user errors where participants failed to use the device correctly by breaking the device capillary tube and not filling the capillary tube. Participants rated acceptability and usability highly, with debut testers giving significantly higher ratings for both. Younger participants gave significantly higher ratings of acceptability.
