Patient centric blood sampling and analysis for diagnostics and laboratory medicine.

Blood sampling and diagnostic laboratory analysis are important aspects of our healthcare systems and patient management. However, the process by which the majority of blood specimens are currently collected, venipuncture, does not put the needs of the patient at the center of the process. This article explores the potential utilization of patient centric sampling (PCS) for the collection of smaller blood volumes using technologies that can enable this sampling to take place at a time and location that is more comfortable and convenient for the patient, including self-sampling at home. We discuss the benefits of these technologies, where they are currently used (including case studies), what to consider when contemplating their use and the current regulatory environment. We then explore why the routine adoption of these technologies has been relatively slow and how this impasse may be overcome for the benefit of all patients. This article describes a viable alternative approach for the collection of diagnostic specimens that puts the requirements of the patient at the center. It provides an invaluable resource for those interested in learning about and potentially implementing this approach into their workflows and addresses the concerns that individuals and organizations may have when doing so.
