Feasibility and Acceptability of Home-Collected Samples for Human Immunodeficiency Virus Preexposure Prophylaxis and Severe Acute Respiratory Syndrome Coronavirus 2 Laboratory Tests in San Francisco Primary Care Clinics

The study found that self-collection of dried blood spots and other samples using at-home kits was a useful and cost-effective method for screening a large cohort for sexually transmitted infections outside a clinic. This demonstrates the feasibility of decentralised, patient-centric sampling for population-level infectious disease surveillance.

This pilot study demonstrated that a fully remote web-based testing programme for sexually transmitted and blood-borne infections was feasible and acceptable overall, although participants encountered specific collection challenges with the dried blood spot component.

The study found that DBS testing showed high specificity for HIV, HBV and HCV and perfect sensitivity for HIV and HBV, but lower sensitivity for syphilis and HCV, with creatinine measurements slightly higher than venous samples. Despite challenges in sample adequacy, DBS was acceptable to participants and could support decentralised STI and renal monitoring in men who have sex with men.

Dried blood spot testing achieved high acceptability among Métis community members in a culturally tailored pilot. Participants valued the ease of self-collection, the reduction of logistical barriers and stigma through event-based delivery, and the provision of Métis-specific services, suggesting that community-centred microsampling can expand HIV and sexually transmitted infection screening in decentralised diagnostics.

Most men who have sex with men could self-administer HIV rapid tests and correctly interpret results, but 27% of dried blood spot cards were of poor quality and interpretation was difficult when control lines were absent, suggesting instructions need refinement before decentralised deployment.
