Sample in-vitro detection method

The invention discloses a sample in-vitro detection method, which belongs to the technical field of in-vitro sample detection, and comprises the following steps: S1, sampling: providing a sampling assembly, a sample bin and a detection assembly, and collecting a sample for in-vitro detection by the sampling assembly; s2, sample treatment: feeding the sample into a sample bin by holding a sampling assembly, and dissolving and diluting the sample in the sample bin; s3, transferring the sample: arranging a reagent strip in the detection assembly, arranging a sample conveying channel between the sample bin and the detection assembly, pushing the sampling assembly to move downwards, opening the sample conveying channel, and enabling the diluted sample to be in contact with the reagent strip through the sample conveying channel; s4, sample detection: carrying out photoelectric identification on the reagent strip filled with the sample by a detection assembly, and identifying the color change of the reagent strip; a
