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.

Menstrual blood offers a noninvasive, patient-centric matrix for detecting endometriosis, cervical cancer, and hormonal disorders through self-collected samples. Wearable in-pad biosensors enabling real-time monitoring and long-term tracking could transform fertility evaluation and early disease detection, though standardisation and large-scale validation remain critical gaps.

In a Phase 1 crossover study of etrasimod, self-collected blood microsamples yielded pharmacokinetic exposures comparable to conventional venous sampling, both with and without participant practice sessions. Continuous wearable sensors concurrently enabled real-time remote monitoring of safety vital signs and electrocardiograms, demonstrating the viability of hybrid decentralised designs in early-phase clinical trials.

Microsampling enables less invasive, patient-centric self-collection of capillary blood for remote monitoring of metabolites and lipids, overcoming conventional venipuncture constraints. Recent device innovations address dried blood spot limitations, particularly haematocrit and volume variations, expanding decentralised applications in population health, drug discovery and multi-omics research.

In a 14-day study of youth with neurodevelopmental conditions and chronic pain, multimodal in-home monitoring achieved good accelerometer wear compliance (77% wore devices for at least 7 days) and moderate survey engagement, but adherence to salivary cortisol sampling was low at 28% after excluding protocol violations and dry swabs. Families reported high overall satisfaction and willingness to participate again, highlighting that remote sampling protocols in pediatric populations require iterative tailoring to improve biospecimen collection adherence.

An intensive protocol combining daily at-home saliva collection for ovarian hormones with smartphone-based ecological momentary assessment achieved 85% compliance in 50 female smokers, revealing substantial within- and between-subject heterogeneity in hormone levels, anxiety and nicotine craving.

The study found that smartwatch-based adherence monitoring showed consistent concordance over time and may be more reliable than app or pill count methods in measuring treatment adherence in a decentralised setting. This supports the use of wearable devices as objective tools in patient-centric monitoring for decentralised clinical trials.

Thirty-eight patients with rheumatic diseases showed high engagement with twice-daily smartphone symptom reporting (95% completion) and remote dried blood spot collection (84% returned samples, all viable for C-reactive protein analysis). Although symptoms varied considerably, clinically meaningful CRP changes were rare, confirming the feasibility of integrating microsampling with patient-generated health data in decentralised rheumatology research.

Self-collected saliva sampling in military technicians produced stable post-awakening cortisol parameters across two days, showing the expected rise thirty minutes after waking followed by recovery. Using actigraphy to verify compliance confirms that unsupervised saliva collection in free-living settings delivers reliable data for operational health surveillance of chronically stressed personnel.

The authors implemented a fully remote outpatient trial of hydroxychloroquine prophylaxis in 54 household COVID-19 contacts using self-collected saliva for SARS-CoV-2 RNA PCR testing and a smartphone-based six-lead ECG system for remote cardiac monitoring, with 42 participants completing the study and no serious treatment-related adverse events. The trial numbers were too small to assess prophylactic efficacy, but the experience demonstrates that decentralised enrolment, home diagnostic sampling and remote monitoring can be rapidly deployed in a community health system, while noting that lack of internet access excluded some potential participants.

This study found that higher pre-sleep physiological stress, measured via self-collected saliva, was linked to increased cortical arousal during sleep and more consolidated rapid eye movement sleep in adolescents. The results support the use of decentralised sampling and in-home monitoring to investigate physiological interactions in natural sleep environments.

In youth aged 8–16 years, first-waking saliva cortisol, IL-6 and IL-1β collected at home associate with prior-night actigraphy sleep metrics. Sleep quality confounds interpretation of salivary stress and immune biomarkers in decentralised paediatric microsampling, so protocols must account for it.

Male fire and emergency service workers showed a lower cortisol awakening response and post-awakening cortisol levels the day after a night on-call with a call, likely due to noise, exertion and stress during callouts. This supports the use of decentralised saliva sampling to assess real-world physiological stress responses in working populations.
