Abstract:
An analyte test element for determining the concentration of at least one analyte in a physiological sample fluid having a first and a second surface in a predetermined distance opposite from each other, said both surfaces are provided with two substantially equivalent patterns forming areas of high and low surface energy which are aligned mostly congruent, whereby the areas with high surface energy create a sample distribution system with at least two detection areas, characterized in that the detection areas of first and second surface are also provided with two corresponding patterns of working and reference electrodes of electrochemical detection means. The sample distribution system contained in the inner part of the analyte test element has no mechanical and/or structural features resembling walls, groves, or channels to guide the physiological fluid to the detection areas which leads to an easy, cost efficient and reliable production process. Due to the integrated calibration procedure the analyte test system of the present invention provides reliable results regardless of the blood type, haematocrit level, temperature etc…
Abstract:
An integrated sample testing meter, for instance for measuring blood, comprising a lancing device, an electrochemical sensor and a test strip cartridge disposed in a single modular housing. The test strip cartridge includes a stack of test strips suitable for performing an electrochemical or photometric analysis of a blood sample. The integrated test system automatically dispenses and positions a test strip in proximity to a lancet puncture site, automatically transfers a blood sample to the test strip from the lancet puncture site and automatically analyzes the blood sample after the test strip collects the sample from the puncture site.
