CalScope: methodology and lessons learned for conducting a remote statewide SARS-CoV-2 seroprevalence study in California using an at-home dried blood spot collection kit and online survey

In a pilot mixed-methods study of youth with HIV, mailed HemaSpot-HF kits enabled home-based dried blood spot collection that participants found feasible and acceptable, supporting remote viral load monitoring and a self-management model for decentralised care.

This narrative review surveys remote biospecimen collection products for sexual health research, including dried blood spots and volumetric absorptive microsampling, and concludes that successful implementation needs a multidisciplinary, participant-centred team with sufficient time allocated to the complexities of collection procedures and processes.

A study of older rural US patients found that 96 to 98 per cent of self-collected dried blood spot specimens were successfully analysed for HIV viral load, with high acceptability. However, concordance between self-reported and measured viral load was only 69 to 82 per cent, highlighting the value of objective decentralised microsampling over self-reporting.

Self-collected dried blood spots were used to assess HIV status at 12 months in 1168 participants. Integration of sexual and reproductive health services increased linkage to HIV prevention care within 60 days (adjusted odds ratio 1·68) compared with standard referral, whereas peer support had no effect.

This protocol paper describes a decentralised HIV self-testing trial that enrolled 2093 Black and Hispanic men who have sex with men across 11 US states. The study incorporates laboratory analysis of participant-returned dried blood spot cards to verify self-reported HIV status, illustrating how patient-centric microsampling can be integrated into remote serology screening for underserved populations.
