Collecting blood samples for lab analysis

Blood Specimen Collection For Laboratory Assay Research

Observational Roman Health Ventures Inc. · NCT06046651

This study is testing whether blood samples taken from a finger prick can be just as good as traditional blood draws from a vein for helping with medical tests, making it easier and less stressful for patients.

What this trial studies

This observational study aims to collect capillary and venous blood specimens to support the development and validation of laboratory procedures. It focuses on the viability of capillary blood samples for diagnostic testing, addressing the challenges of traditional venipuncture methods that can cause patient distress. By comparing the results from capillary samples to the gold standard venous samples, the study seeks to enhance remote health monitoring and improve patient compliance. The research will also explore the stability of these samples under various conditions.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older in good general health who can provide both capillary and venous blood samples.

Not a fit: Patients unable to provide blood samples due to illness or those with acute or chronic medical conditions may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accessibility and comfort of blood testing for patients.

How similar studies have performed: While there is limited data on the stability of capillary samples, the approach of using capillary blood for diagnostics is gaining traction and has shown promise in preliminary studies.
