Test strip cassette, monitoring device and method for fabricating a test strip cassette

A method for fabricating a test strip cassette, comprising:

• providing a carrier comprising at least one photodetector;
• providing a test strip comprising a sample pad and at least one active area;
• providing a housing defining a first opening being configured to receive a sample liquid, the housing further defining a second opening configured to provide an optical path into the housing, and comprising a spacer structure;
• and
• assembling the housing, the test strip and the carrier such that the housing encloses the carrier and the test strip, the test strip being spaced from the carrier by the spacer structure and arranged between the second opening and the carrier, wherein the at least one photodetector, the at least one active area and the second opening are aligned to each other, and wherein the sample pad is aligned with the first opening of the housing.
