A urine self-test may verify PrEP adherence, aiding HIV prevention
NCT ID NCT07792161
First seen Aug 28, 2026 · Last updated Aug 28, 2026
Summary
Researchers are testing whether a urine-based self-test can accurately detect tenofovir, a drug used in PrEP for HIV prevention. The study enrolls HIV-negative women in North Carolina who use stimulants and are either on PrEP or eligible for it. Participants will complete the self-test remotely, and researchers will compare those results with a lab reference test to measure the self-test's sensitivity and specificity. If accurate, this approach could make it easier to monitor PrEP adherence without clinic visits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- urine-based self-test for tenofovir (PrEP adherence)
- What this could lead to
- If the self-test proves accurate, it could offer a simple, remote way to monitor PrEP adherence, supporting HIV prevention efforts in women who use stimulants.
- What could go wrong
- This is a small, early-stage diagnostic study. The self-test may not match lab accuracy, and results may not apply beyond this specific group.
