METHODS OF DETECTING TEST ELEMENTS HAVING DEGRADED TEST CHEMICALS AS WELL AS APPARATUSES INCORPORATING THE SAME

摘要

An analytical apparatus is disclosed for detecting at least one analyte in a sample, where in an analyte measurement at least an electrical or optical property changeable by presence of the analyte at least one test chemical of a test element is recorded, and where the analytical apparatus also can perform at least one quality measurement on the at least one test chemical such as an intrinsic luminescence, which is recorded and from the intrinsic luminescence a conclusion is drawn on a quality of the test chemical and thus the test element. Methods also are disclosed for detecting at least one analyte in a sample that include a quality measurement of the at least one test chemical of the test strip.
