MeasureTime frameDescription
Intracellular Level of Tenofovir Diphosphate Levels Via Dried Blood Spot at 6-month Follow-up6 monthsTenofovir diphosphate levels will be quantified using a validated dried blood spot (DBS) assay. The outcome will be reported as the mean intracellular concentration (fmol/punch) at the 6-month follow-up visit. This measure reflects intracellular drug exposure and adherence.

Outcome results

Primary

Intracellular Level of Tenofovir Diphosphate Levels Via Dried Blood Spot at 6-month Follow-up

Tenofovir diphosphate levels will be quantified using a validated dried blood spot (DBS) assay. The outcome will be reported as the mean intracellular concentration (fmol/punch) at the 6-month follow-up visit. This measure reflects intracellular drug exposure and adherence.

Time frame: 6 months

Population: Specimens were collected but none met laboratory acceptance criteria (insufficient punch volume and degradation). Therefore, no valid concentrations could be calculated. All values are reported as Not Analyzable.

Time to PrEP Initiation Post Negative HIV Rapid Test

Number of days between receiving negative test result and initiating PrEP via self-report

Time frame: up to 12 months

Population: All participants-initiated PrEP immediately following their negative test result. Because initiation occurred on the same day as the negative test (day 0), the calculated value for every participant was zero days
