The above detection operation needs to be completed in a short time, and is easy to leak, the biological safety cannot be guaranteed, and there is a possibility of mutual infection. Therefore, the utility model patent CN220861507U discloses a self-detection sample reagent tube, which comprises a tube body and a swab assembly. A separation cavity is arranged in the tube wall of the tube body, and a detection test paper is arranged in the separation cavity.
