    摘要： A method for detecting an analyte in a body fluid is disclosed. The method has the following steps: a) applying a sample (122) of the body fluid to a test element (120), said test element (120) comprising at least (i) a test field (128) comprising at least one test material (130) adapted to change at least one measurable property in the presence of the analyte, (ii) a capillary element (126) adapted to guide the sample (122) across said test field (128) in a flow direction (146), (iii) a first and a second measurement location (158, 160) within said test field (128), wherein the second measurement location (160) is offset from the first measurement location (158) in the flow direction (146); b) measuring the measurable property in said at least one first measurement location (158), thereby generating at least one first measurement value; c) measuring the measurable property in said at least one second measurement location (160), thereby generating at least one second measurement value; d) detecting the analyte by using an evaluation algorithm having at least two input variables, wherein (i) at least one first input variable of the at least two input variables includes an information on a difference between the first measurement value and the second measurement value, and (ii) at least one second input variable of the at least two input variables includes a measurement information on an analyte-induced change of the measurable property of the test material (130) in at least part of the test field (128).

    摘要： A test element analysis system (130) for the analytical examination of a sample, in particular of a body fluid, is disclosed. The test element analysis system (130) comprises: - at least one evaluation device (158) with at least one test element holder (142) for positioning a test element (110) containing the sample and at least one measuring device (160) for measuring a change in a measuring zone (118) of the test element (110), the change being characteristic for the analyte; - at least one electrical heating element (132) configured for electrically heating the test element (110); - at least one electrical power supply (148) for supplying electrical energy to the electrical heating element (132); - at least one temperature sensor (140) connected to the test element holder (142) for detecting a temperature of the test element holder (142); - at least one gap detection device (150) configured for monitoring the electrical energy E spez supplied by the electrical power supply (148) to the electrical heating element (132) for reaching a predetermined target temperature measured by the temperature sensor (140).
