At-home dried blood spot (DBS) collection to increase population heterogeneity representation in pediatric research: An ECHO study
Green et al.
The finding, in our words
Self-collection of dried blood spots in the home was feasible for healthy youth, with 82% consenting to provide a sample in the lab and 75% of those willing to self-collect at home, and DNA extraction quality was high across demographic groups.

Dried blood spot collection proved feasible during parabolic flight, with seventeen of twenty volunteers successfully providing samples for caffeine pharmacokinetic profiling. The method yielded stable metabolic ratios between ground and weightless conditions, and participants reported high satisfaction, suggesting DBS could support therapeutic drug monitoring in remote or extreme environments such as long-term spaceflight.

This study demonstrated that a fully remote genome sequencing study using self-collected dried blood spots and buccal swabs is feasible for individuals with Prader-Willi syndrome, with all participants completing the study and reporting the process was easy despite being lengthy. The design successfully returned actionable genetic findings, including those related to blood clot formation, to participants.

Dried blood spot sampling matched venous serum performance for islet autoantibody detection and was considered minimally invasive and convenient by parents and stakeholders, supporting its use for decentralised screening in home or community settings.

Whole-genome sequencing of dried blood spots from 1,000 newborns identified 16 infants with high-chance results, most missed by standard screening. The 13-day turnaround and high parental acceptability show a feasible, scalable model for decentralised genomic screening.
Primary caregivers of children with metabolic disorders found at-home dried blood spot collection acceptable after training, which could enable more timely and cost-effective monitoring. This supports the feasibility of decentralised, patient-centric sampling for long-term condition management.
