Web-Delivered Multimedia Training Materials for the Self-Collection of Dried Blood Spots: A Formative Project
Allen et al.
The finding, in our words
Web-delivered multimedia training for self-collection of dried blood spots was acceptable to 98% of participants and produced usable samples in 96% of attempts, indicating that remote instruction can enable reliable patient-centric microsampling, though response rates to recruitment need improvement.

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.

The study found that although participants preferred patient-centric microsampling devices for home use, the agreement with venous plasma for measuring CRP and cytokines was inconsistent, indicating that further validation is required before these methods replace standard venipuncture.
In a 20-person proof-of-concept pilot among veterans with HIV, remote self-collection of dried blood spots for phosphatidylethanol monitoring was feasible and acceptable, with high return and analysis rates and positive feedback; a small first step toward decentralised alcohol biomarker monitoring rather than proof of it.

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.

The study found that quantitative dried blood spot sampling provided high clinical agreement for tacrolimus and creatinine monitoring, with patients rating the self-collection devices as user-friendly. These results support the feasibility of decentralised therapeutic drug monitoring for immunosuppressants.
