Suitability and Sufficiency of Telehealth Clinician-Observed, Participant-Collected Samples for SARS-CoV-2 Testing: The iCollect Cohort Pilot Study
Guest et al.
The finding, in our words
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.

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.

The study validated a semi-quantitative protocol for Epstein-Barr virus serology using dried blood spots, demonstrating 98.8% sensitivity and 96.5% specificity compared to paired venous serum samples. The successful validation in a self-sampling cohort confirms the suitability of this patient-centric microsampling approach for large-scale seroprevalence studies and decentralised trials.
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 review establishes that microsampling across blood, saliva, urine and stool matrices offers validated workflows and regulatory recognition for human biomonitoring comparable to conventional methods. It finds that these decentralised approaches enhance participant acceptability and enable screening in remote or low-resource settings.
In a study of 46 perinatal nicotine users, dried blood spots and saliva were used weekly to measure reproductive hormones, finding that lower postpartum estradiol and greater peripartum declines in oxytocin were associated with increased nicotine craving and use. This demonstrates the feasibility of decentralised microsampling and remote surveys for longitudinal hormone tracking in vulnerable populations.
