    Abstract: PROBLEM TO BE SOLVED: To provide a method for measuring an analyte in a liquid sample by means of an examination system which includes two compartments. SOLUTION: A detection reaction, necessary for measuring the analyte in the liquid sample, is carried out in the inside of a first compartment, and analytical measurement of an index substance, which is at least one substance concerned with the detective reaction and different from the analyte, is carried out inside side a second compartment. Two compartments allow the index substance to enter the second compartment, and separation is carried out, while at least partially preventing entrance of another substance, capable of disturbing the analytical measurement of the index substance in the second compartment. As a captured substance, at least another substance capable of selectively condensing the index substance in the inside of the second compartment is fixed inside the second compartment. The analyte can be measured by using this examination system. COPYRIGHT: (C)2005,JPO&NCIPI

    Abstract translation: 要解决的问题：提供一种通过包括两个隔室的检查系统来测量液体样品中的分析物的方法。 解决方案：测量液体样品中的分析物所需的检测反应在第一隔室的内部进行，并且分析测量作为与检测反应有关的至少一种物质的指示物质，以及 与分析物不同，在第二隔室内侧进行。 两个隔间允许指示物质进入第二隔室，并进行分离，同时至少部分地防止能够扰乱第二隔室中指示物质的分析测量的另一物质的入口。 作为捕获物质，至少能够将第二隔室内部的指示物质选择性冷凝的另一物质固定在第二隔室内。 可以通过使用该检查系统来测量分析物。 版权所有（C）2005，JPO＆NCIPI

    Abstract: 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).

    Abstract: The invention concerns a method for determining an analyte in a liquid sampl e by means of a test system consisting of at least two compartments wherein the detection reactions necessary to determine the analyte in the liquid sample are carrie d out in a first compartment and an analytical determination of at least one substance which participates in the detection reactions and is different from the analyte, t he indicator substance, takes place in a second compartment characterized in that the two compartments are separated in a manner which allows the indicator substance to pass into the second compartment and at least partially prevents passage of other substances that could interfere with the analytical determination of the indicator substance in the second compartment and that at least one other substance which, as a capture substance, can selectively enrich the indicator substance in the second compartment, is present in an immobilized form in the second compartment. Other subject matters of the invention are test systems for carrying out such methods and the use of these test systems for the determination of analytes according to the invention.
