A method for manufacturing a test element for detecting at least one analyte in a body fluid, a test element for detecting at least one analyte in a body fluid, a method for detecting at least one analyte in a body fluid, a system for detecting at least one analyte in a body fluid and a method for manufacturing a test element for detecting at least one analyte in a body fluid are disclosed. The method for manufacturing a test element for detecting at least one analyte in a body fluid comprises the following steps: wherein at least one hydrophilic material is applied in a manner that at least one surface section of the channel surface is covered with the hydrophilic material, wherein the surface section is adjacent to the test chemical.

Method for manufacturing a test element for detecting an analyte in a body fluid

Methods are disclosed for manufacture of test elements for detecting at least one analyte in a body fluid, where the test elements include a housing having at least one base element and at least one cover element. The methods include providing the base element, and mounting the cover element to the base element with an adhesive, wherein the adhesive contacts at least one test field of the cover element such that the adhesive is interposed between the test field and the base element and at least partially covers the test field. The test elements also include at least one fluid channel formed within the housing, where the the fluid channel includes a capillary region and a measurement region. The capillary region and the measurement region have differing aspect ratios. The at least one test field has at least one test chemical, where the test chemical is adapted to change at least one optically measurable property in the presence of the analyte.
