Improving Clinical Decisions Via Remote Blood Sampling

ABSTRACT

3 An important component for the provision of patient-centric healthcare is the ability to collect blood samples remotely in a manner that delivers samples of a quality comparable to that of current standard phlebotomy collection, enabling routine clinical testing, monitoring disease progression and testing drug concentrations.2-4-г, This blood sampling could be performed at the patient's home, at a nearby pharmacy, or at a local clinic, rather than a centralized facility. Examples of commercially available devices include the Neoteryx Mitra,13 Tasso-M20, SST and Tasso+,14 SeventhSense TAP and TAP II,15 Trajan hemaPEN,16 Labcorp Pixel,17 Capitainer qDBS,1" HemaXis DB10 and DX,19 and Drawbridge OneDraw.20 These devices are capable of collecting from as little as 20 microliters (approximately half a drop) to several hundred microliters of blood and have been widely used to determine clinical parameters,21 drug concentrations,5'22 therapeutic drug monitoring,23 and, more recently, COVID antibody levels.24,25 Some of these devices enable the collection of a fixed volume of blood, collected as dried blood, which can then be shipped and handled at room temperatures-avoiding the need for freezers and dry ice for storing and shipping samples-enabling its adoption even in remote areas with limited infrastructure. Patient-centric blood sampling techniques have been gaining popularity for use in pharmaceutical drug development;however, to date they have not been broadly accessible to the general public.26 This can be partially attributed to the "cliniccentric" healthcare model, where reimbursement is dependent on in-person visits and sample collection. [...]the status quo remains and anyone who needs a blood test is required to go to the doctor's office or clinic. [...]studies have demonstrated that the overall cost to society will be lower, by improving health outcomes and allowing broader access and patient convenience.27 The availability and adoption of patient-centric approaches can provide access and treatment options to clinical trial participants not geographically co-located with the investigative sites and improving access in rural or lesser developed communities, globally, potentially improving the health of the general population.
