Abstract

The present invention relates to the field of biological sample testing technology, and in particular, to a testing system. The testing system includes a reagent reaction vessel and a test device. A reagent storage portion and a push rod movable relative to the reagent storage portion are packaged in the reagent reaction vessel, the reagent storage portion comprises at least one reagent containing cavity, and the reagent containing cavity is sealed by a sealing element; and the push rod is connected to the sealing element, and the push rod is used for cooperation with the test device to separate the sealing element from the reagent storage portion. The test device includes a test cassette, wherein an ejection rod is arranged in the test cassette, and the ejection rod cooperates with the push rod to separate the sealing element from the reagent storage portion. According to the present invention, when the reagent storage portion is inserted, the ejection rod can be quickly pushed to operate, and one operation completes multiple functions such as releasing the reagent, fixing the reagent reaction vessel, and focusing on a test area at the same time, thereby simplifying the reaction steps.
