Abstract
An aqueous control liquid is provided that contains glucose at a known concentration and cyclodextrin. A method is also provided that binds a wetting agent from a region of a test element that comes into contact with a sample. The method includes contacting the region with a control liquid that has a substance selected from the group of cyclodextrin derivatives and dispersed materials having a specific surface of 100 m /g to over 1000 m /g. A method for controlling the function of a measuring system having test strips and a measuring instrument for the determination of glucose in liquid samples is provided that includes contacting the test strip with a control liquid containing glucose at a known concentration and at least one substance selected from the group consisting of cyclodextrins and cyclodextrin derivatives and detecting a signal caused by the glucose contained in the control liquid.
