METHOD AND SYSTEM FOR DETECTING AN ANALYTE IN A BODY FLUID |
摘要 |
A method for detecting at least one analyte in a body fluid (112) is disclosed. The method comprises the following steps: a) performing an optical measurement, wherein at least one test chemical (120) is contacted with the body fluid (112), wherein the test chemical (120) is an optical test chemical (120) and is adapted to perform at least one detection reaction in the presence of the analyte, wherein at least one optically detectable property of at least one of the body fluid (112) and the test chemical (120) is changed due to the detection reaction, wherein at least one optical measurement value is generated; b) performing at least one impedance measurement, wherein at least two impedance measurement electrodes (130) are used, wherein at least one alternating electrical signal is applied to the body fluid (112) via the impedance measurement electrodes (130) and wherein at least one answer signal is recorded, wherein at least one impedance measurement value is generated; c) performing at least one evaluation step, wherein, in the evaluation step, at least one evaluation algorithm is used, wherein the optical measurement value and the impedance measurement value are used for determining a concentration of the analyte in the body fluid (112). |
