A test strip kit use for storing a test strip and a testing device. The test strip kit comprises a first cover plate (2) and a second cover plate (3). When in use, the first cover plate (2) and the second cover plate (3) are assembled together, and a test strip (100) is mounted therein. A volume-controlled sample adding channel (5) is provided on the first cover plate (2). The volume-controlled sample adding channel (5) comprises a section of capillary channel in proximity to a sample adding opening. By utilizing the capillary principle, the volume-controlled sample adding channel (5) automatically draws therein a liquid sample (102) in contact with the sample adding opening (4). The test strip kit used for storing the test strip and the testing device not only implement automatic collection of the liquid sample, but also allow effective control of the volume of a liquid being added and prompting of whether same satisfies the minimum amount for testing, are applicable in multiple testing fields such as physio
