Patent ID: 7901875

Claim:
An analyte test element for determining the concentration of at least one analyte in a physiological or aqueous sample fluid having a first surface ( 2 a ) and a second surface ( 4 a ) 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 to create a sample distribution system ( 6 ) with at least two detection areas ( 6 a ), wherein the applied physiological or aqueous fluid is substantially constrained to the areas with high surface energy, and wherein n predetermined detection areas ( 6 ′ a ) of said first surface ( 2 a ) are coated with a catalytic formulation promoting the detection of an analyte in a physiological or aqueous fluid, and n predetermined detection areas ( 6 a ) of said second surface ( 4 a ) are coated with n calibration formulations made up of m blank formulations and n-m formulations with different levels of calibration compound, whereby n is an integer number larger than 2, m is an integer number equal or larger than 1, and n>m.
