A Narrative Review of Remote Biospecimen Collection Product and Implementation Considerations for Sexual Health Clinical Research
Horvath et al.
The finding, in our words
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.

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.
Most telehealth-supervised, participant-collected saliva, oropharyngeal swab, and dried blood spot specimens were judged suitable and biologically sufficient for SARS-CoV-2 RNA and serology testing in a pilot cohort. This validates decentralised, patient-centric microsampling for infectious disease screening.

In AML and CLL, 91% of VAMS venetoclax results fell within 20% of plasma after individualised haematocrit correction; in home sampling, 18 of 21 patients self-sampled independently and 76% of returned samples were analysable, which shows home microsampling is workable, though the authors ask for multicentre validation.

This review found that volumetric microsampling devices, such as Mitra, HemaPEN, HemaXis DB10, and Tasso-M20, overcome haematocrit bias, whilst Telimmune plasma separation cards enable direct plasma collection without centrifugation. These technologies support patient-centric, decentralised sampling, though the authors note that clinical validation remains limited across different drugs and patient populations.
