Blood Sample Collection Study to Compare Fingerstick and Venous Blood for Laboratory Research Includes At-Home and Clinic-Based Collection for Adults 18 and Older

What this Trial Is About

Researchers are studying how blood samples collected through fingerstick capillary compare to traditional venous blood samples for lab testing. This observational study aims to understand the stability of capillary blood samples under different environmental conditions and over time to support the development of lab procedures. The study addresses the need for easier, less distressing blood collection methods to expand diagnostic access and improve disease monitoring remotely. Participants may collect capillary blood themselves or have venous blood drawn by healthcare professionals at designated facilities or their homes. Capillary samples are collected via fingerstick using a lancet, with up to four samples per visit, while venous samples are collected through standard venipuncture methods. Samples are then processed and analyzed under various conditions such as temperature, humidity, light exposure, and freeze-thaw cycles to evaluate specimen stability and assay reliability. Participants provide blood samples either during a single visit or multiple visits over time until withdrawal or study end. The study includes collection of health information and consent, with compensation upon sample submission. Researchers will assess the correlation between capillary and venous samples and monitor sample stability over several days. The study is designed with minimal risk, involving routine procedures and safety monitoring, continuing until study closure or participant withdrawal.
