Abstract
A biological diagnostic device and process for efficiently and accurately analyzing a sample of a biological fluid for in analyte of interest. The device, which is a preferred embodiment utilized for the analysis of whole blood samples, comprises a diagnostic test element and a sample application unit comprising a fluid delivery element and means for providing sample fluid to the fluid delivery element. The fluid delivery element comprises a layer having a plurality of grooves, or channels, in the surface thereof which is adjacent the test element. The fluid which is provided to the grooves is subsequently delivered to the test element.
