Supporting Health and Empowerment Through Contingency Management and Affect Regulation (SHE CARES)

The goal of the SHE CARES study is to better understand factors that influence engagement in HIV prevention and substance use services among women who use stimulants in North Carolina. This part of the SHE CARES study will assess agreement between a remotely completed, participant-administered urine-based test for PrEP use and an in-person laboratory reference test.

Detailed Description

Validation study to evaluate the real-world performance of remotely completed, participant-administered urine-based self-tests (index test) compared with clinic-based laboratory reference testing among stimulant-using women who inject drugs in North Carolina. The reference standard will be plasma tenofovir concentrations measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS).

Intervention / Treatment
Experimental: SHE CARES Validation Cohort

Women who use stimulants who are currently using oral PrEP or are not currently using PrEP will complete a participant-administered urine-based tenofovir self-test (index test) and clinic-based laboratory reference testing. The reference standard will be plasma tenofovir concentrations measured using liquid chromatography-tandem mass spectrometry (LC-MS/MS).
Diagnostic test: urine-based self-test

participant-administered urine-based self-tests (index test)

Diagnostic test: urine-based clinic test

plasma tenofovir concentrations measured by liquid chromatography-tandem mass spectrometry in the clinic (gold standard)
