Abstract
A reagent test strip for measuring an analyte concentration in a biological fluid has a spreading mesh sandwiched between a support and a reagent matrix. The support has a through hole that is covered by the mesh. In use, a sample of the fluid is applied through the hole in the support to the spreading mesh. The sample then passes through the mesh to the matrix, which contains a reagent that indicates the analyte concentration by causing a corresponding change in reflectance at its free surface. Optionally, an adhesive layer attaches the mesh, and optionally the matrix as well, to the support.

Method and apparatus for obtaining blood for diagnostic tests

TL;DR: In this article, a method and apparatus for obtaining a sample of blood from a patient for subsequent diagnostic tests, e.g., glucose monitoring, is described. But the method comprises the steps of: (a) forming an unobstructed opening in the area of the skin from which the sample is to be extracted; and (b) extracting the sample of the blood from the unobstructed open in the skin, with the aid of a vacuum and a stretching of skin.
