A test element analysis system for the analytical examination of a sample is disclosed. The test element analysis system comprises: at least one evaluation device with at least one test element holder for positioning a test element containing the sample and at least one measuring device for measuring a change in a measuring zone of the test element, the change being characteristic for the analyte; at least one electrical heating element configured for electrically heating the test element; at least one electrical power supply for supplying electrical energy to the electrical heating element; at least one temperature sensor connected to the test element holder for detecting a temperature of the test element holder; at least one gap detection device configured for monitoring the electrical energy Esupplied by the electrical power supply to the electrical heating element for reaching a predetermined target temperature measured by the temperature sensor.

Test element analysis system for the analytical examination of a sample

Methods for detecting an analyte in a body fluid are described as well as devices and systems adapted for performing such methods. In embodiments of the method, a sample of body fluid is applied to a test element having at least one test field including at least one test material that is adapted to change at least one measurable property in the presence of the analyte. The test element further includes a capillary to guide the sample across said test field in a flow direction. The test element also includes first and second measurement locations offset from each other in the flow direction. The measurable property is measured in at least one first measurement location, providing at least one first measurement value, and it is measured in at least one second measurement location, providing at least one second measurement value. The analyte is detected by using an evaluation algorithm having at least two input variables, wherein at least one first input variable of the at least two input variables includes a difference between the first measurement value and the second measurement value, and at least one second input variable of the at least two input variables includes information relating to an analyte-induced change of the measurable property of the test material in at least part of the test field.
