METHOD AND DEVICE FOR DETERMINING AN ANALYTE CONCENTRATION IN BLOOD

摘要

A method is proposed for determining at least one concentration of at least one analyte in blood, in particular for determining a blood glucose concentration. In the process, use is made of a test element (114), which comprises at least one test chemical (124). The test chemical (124) is designed to carry out at least one optically detectable detection reaction if the analyte is present. The blood is applied onto the test element (114) and a time profile of at least one optical measurement variable of the test chemical (124) is detected. At least one disturbance variable in the blood, in particular a concentration of a disturbance component and preferably a haematocrit in the blood, is deduced from at least a first period of time (158) of the time profile of the optical measurement variable. The concentration of the analyte is deduced from at least a second period of time (164) of the time profile.
