Proteomic Profiles from At-Home Dried Blood Samples for 16 Individuals

Dried blood samples from 16 individuals, collected using Tasso M20 devices, were analyzed via the SomaScan Assay and compared to plasma and serum from the same donors. The dataset, authored by Weston J. Smith and last updated in May 2026, includes measurements for over 800 proteins and models predicting complete blood counts from proteomic data.

Use Cases

• Comparing protein measurement consistency between dried blood samples and plasma/serum based on the described cross-sectional analysis.
• Developing predictive models for complete blood counts (CBCs) based on SomaScan Assay measurements mentioned in the description.
• Identifying cell-secreted or surface proteins measurable in dried blood samples based on the over 800 proteins reported.
• Evaluating the clinical utility of at-home, patient-centric blood collection methods for affinity proteomics applications.

Strengths

• Includes matched data from three sample types (dried blood, plasma, serum) for 16 individuals, enabling direct comparison.
• Identifies over 800 proteins that can be measured in both plasma and dried blood samples.
• Models generated from dried blood sample data reportedly predict complete blood counts more accurately than those from plasma.

Limitations

• Row count is unknown, which may limit suitability assessment for machine learning tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• Dataset is very small at 12.5 KB, indicating limited scope and sample size.
