Abstract
A microfluidic device comprising a flow channel that utilizes various principles of fluid dynamics to simplify the processes of preparing a sample prior to in vitro diagnostic analysis. A flow channel wherein flow conditions result in a Reynolds number no greater than about 2000, preferably no greater than about 1000, provides enhanced separation of blood cells from a liquid medium, i.e., serum or plasma.
