Patent ID: 10900957

Abstract:
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.
