What this trial studies

This observational study involves participants self-collecting capillary blood samples using the Tasso+SST device at two visits spaced at least 14 days apart. Healthcare providers will also collect capillary and venous serum samples for comparison. The collected samples will be analyzed for various serum analytes to assess the accuracy and reliability of the Tasso+ device against traditional venous samples. The study aims to determine if self-collected samples can provide comparable results to those obtained by healthcare professionals.

Who should consider this trial

Good fit: Ideal candidates are healthy adults aged 18 to 85 who can provide informed consent and have analyte values within clinical reference ranges.

Not a fit: Patients with abnormal skin integrity near the collection sites or those with mental or physical impairments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enable easier and more accessible blood sample collection for patients.

How similar studies have performed: While similar approaches have been explored, this specific evaluation of the Tasso+SST device is relatively novel.
