Claim:
1. A test element for determining at least one analyte concentration in a sample having at least one interfering variable, the test element comprising: at least one test chemistry on a test support of the test element, wherein the at least one test chemistry is configured to carry out at least one detectable reaction with at least one analyte, wherein the test chemistry is completely or partly contained in at least one first region of the test support of the test element; and at least one diffusable label in the at least one first region of the test element, wherein the at least one diffusable label is configured to diffuse at least partly from the at least one first region of the test element into at least one second region of the test element, wherein the at least one test chemistry and the at least one diffusable label provide at least one piece of correction information from a detected diffusion of the at least one diffusable label, the at least one piece of correction information accounting for an influence of the at least one interfering variable and accounting for a general relationship between the at least one interfering variable and diffusion of the at least one diffusable label, wherein the at least one interfering variable is one or more of a temperature of the sample, a temperature of a testing environment, and hematocrit of the sample, and wherein the general relationship is obtained from at least one, predetermined calibration measurement.
